schwit1 shares a report from NPR: When you first approach this bridge over Interstate 66 in northern Virginia, it may feel like you're driving on the wrong side of the road. Because, in a way, you are. "There were a lot of people who looked at me like I was a little nuts," says traffic engineer Gilbert Chlewicki, the inventor of this unconventional interchange. "Like, why are you putting me on the other side of the road?" Chlewicki agreed to meet at this intersection 35 miles west of Washington, D.C. to explain the workings of the diverging diamond interchange, as it's known. He was easy to spot, wearing a neon yellow vest for safety. As you enter the interchange, the right and left sides of the road cross over each other at a stop light. You are, in fact, driving on the left side of the road at this point. From there, left turns become a lot easier, because there's no oncoming traffic in the way. Instead of waiting for a signal, you get a free left turn. "When we do the cross-over to the left side of the road, that's when the left turns happen, so the left is very easy," says Chlewicki. That means diverging diamond interchanges can be both more efficient and safer than conventional intersections with left turn lanes. There are now more than 200 of them across the U.S., in more than 30 states. But at first, it wasn't easy to convince other traffic engineers. "Anything different is a hard sell," Chlewicki said. "Safety was the big question." In 2009, Missouri became the first state to install a diverging diamond interchange (DDI) at a congested intersection in Springfield. This new design quickly reduced traffic congestion and significantly improved safety, with crashes decreasing by 40-50%. However, drivers have mixed feelings about the design. Some, like school bus driver Logan Wilcox, feel it can be confusing and potentially dangerous for unfamiliar drivers. Others, like local driver Greg Peterson, praise it for improving traffic flow and reducing accidents.

Sales of SUVs hit a new record in 2023, making up half of all new cars sold globally, data has revealed. Experts warned that the rising sales of the large, heavy vehicles is pushing up the carbon emissions that drive global heating. From a report: The analysis, by the International Energy Agency, found that the rising emissions from SUVs in 2023 made up 20% of the global increase in CO2, making the vehicles a major cause of the intensifying climate crisis. If SUVs were a country, the IEA said, they would be the world's fifth-largest emitter of CO2, ahead of the national emissions of both Japan and Germany. Climate-fuelled extreme weather is increasing, with urgent cuts in emissions needed. But emissions from the global transport sector have risen fast in recent years, outside of the Covid pandemic. SUV sales rose 15% in 2023, compared with a 3% rise for conventional cars. There were more than 360m SUVs on the roads worldwide in 2023, producing 1bn tonnes of CO2 emissions, up about 10% on 2022. As a result, global oil consumption rose by 600,000 barrels a day, more than a quarter of total growth in oil demand, the IEA said. SUVs weigh 200-300kg more than an average medium-sized car and emit about 20% more CO2. In rich countries, almost 20m new SUVs were sold in 2023, surpassing a market share of 50% for the first time. Globally, 48% of new cars were SUVs and, including older cars, one in four cars on the road today are SUVs, according to the IEA.

Nashville-based Yoshi Mobility launched in 2015 to deliver gasoline to vehicle owners, reports Forbes. But this week the company announced they'll begin converting GM electric delivery vans into "mobile EV superchargers" — fast, battery-powered 240 kw DC chargers — for corporate fleets of electric cars. "There's kind of this critical grid problem and so we think that we can accelerate towards an EV future and this is a unique way that we can do it," said [cofounder/CEO Bryan] Frist in an interview. "The mobile charger can charge and then it can multiplex all the spots. So we tell people, it can electrify every spot in your parking lot." Each mobile supercharger can service between five and seven vehicles according to Frist. With perhaps two superchargers operating on a fleet operator's lot, one would service a vehicle while the other supercharger would replenish its own charge off the grid and they would alternate, according to Frist. "What we say is we can do that same charge instead of three and a half hours, we can do in 10 minutes, and we can move around your lot," Frist says. "You don't have to put in all the infrastructure. You don't have to build it out. You just contract with us." The company plans to begin with a "handful" of mobile superchargers in [GM's] BrightDrop vans but expects to ramp up production and begin commercializing more widely during the first quarter of 2025... The mobile superchargers will complement Yoshi Mobility's existing offering of high-capacity mobile generators that sit on a fleet operator's lot putting out as much as a megawatt of power and can service a larger number of vehicles than the mobile units.

"64% of Americans live within 2 miles of a public charging station," Pew Research reported this week, citing a survey paired with an analysis of U.S. Energy Department data that found over 61,000 publicly accessible charging stations. And those who live closest to public chargers "view EVs more positively." The vast majority of EV charging occurs at home, but access to public infrastructure is tightly linked with Americans' opinions of electric vehicles themselves. Our analysis finds that Americans who live close to public chargers view EVs more positively than those who are farther away. Even when accounting for factors like partisan identification and community type, Americans who live close to EV chargers are more likely to say they: - Already own an electric or hybrid vehicle - Would consider buying an EV for their next vehicle - Favor phasing out production of new gasoline cars and trucks by 2035 - Are confident that the U.S. will build the necessary infrastructure to support large numbers of EVs on the roads The number of EV charging stations has more than doubled since 2020. In December 2020, the Department of Energy reported that there were nearly 29,000 public charging stations nationwide. By February 2024, that number had increased to more than 61,000 stations. Over 95% of the American public now lives in a county that has at least one public EV charging station. EV charging stations are most accessible to residents of urban areas: 60% of urban residents live less than a mile from the nearest public EV charger, compared with 41% of those in the suburbs and just 17% of rural Americans. California is home to about 25% of all of America's charging stations, according to the report. But this means EV-owning Californians "might also have a harder time than residents of many states when it comes to the actual experience of finding and using a charger." Despite having the most charging stations of any state, California's 43,780 individual public charging ports must provide service for the more than 1.2 million electric vehicles registered to its residents. That works out to one public port for every 29 EVs, a ratio that ranks California 49th across all 50 states and the District of Columbia. At the other end of the spectrum, Wyoming (one-to-six), North Dakota (one-to-six) and West Virginia (one-to-eight) have the most ports relative to the much smaller number of EVs registered in their respective states. Another interesting finding? "Attitudes toward EVs don't differ that much based on how often people take long car trips. "In fact, those who regularly drive more than 100 miles are slightly more likely to say they currently own an electric vehicle or hybrid — and also to say they'd consider purchasing an EV in the future — when compared with those who make these trips less often."

Malaysia Airlines Flight 370 vanished in 2014 — and efforts continue to find it. In 2018 a UK-based video producer claimed to have discovered the crashed aircraft on Google Maps — but Newsweek pointed out the same wreckage "is visible in imagery dating back to January 1, 2004 — more than a decade before MH370 disappeared." Marine robotics company Ocean Infinity also failed to find the aircraft after a five-month search in 2018 — but has returned to the headlines this March, writes the Independent, "claiming that they have scientific evidence" for the flight's final resting place. (The company's CEO says the last six years they've been "innovating with technology and robotics to further advance our ocean search capabilities.") And this week Indian Express reported that researchers from the UK's Cardiff University investigating the mystery "have come up with a novel plan to unravel it — sea explosions." More from the Economic Times: Scientists have said that airplanes crashing over oceans create unique acoustic signatures that can travel more than 3,000km through water. These acoustic signatures can be recorded by a network of 11 hydroacoustic stations worldwide that are dotted along the seabed. Researchers at Cardiff University have said that a series of controlled underwater explosions or air gunfire along the 7th arc [where the plane last communicated] can be done to see whether they can isolate a more precise location for MH370. More details from NDTV: "[W]ithin the time frame and location suggested by the official search, only a single, relatively weak signal was identified,'' Dr Kadri said... ''Similar exercises were performed in the search and rescue mission for the ARA San Juan, a submarine that vanished off the coast of Argentina in 2017. This shows us that it is relatively straightforward and feasible and could provide a means to determine the signal's relevance to MH370, prior to resuming with another extensive search. If found to be related, this would significantly narrow down, almost pinpoint, the aircraft's location,'' Dr Kadri added... Despite the largest search in aviation history, the plane has never been found. An announcement from Cardiff University adds that "The experiments would also help develop the use of hydroacoustic technology as a tool for authorities to draw upon when narrowing down potential crash locations for airplanes in the future."

Nine more accidents have been discovered by federal safety regulators during their safety investigation of Waymo's self-driving vehicles in Phoenix and San Francisco. TechCrunch reports: The National Highway Traffic Safety Administration Office of Defects Investigation (ODI) opened an investigation earlier this month into Waymo's autonomous vehicle software after receiving 22 reports of robotaxis making unexpected moves that led to crashes and potentially violated traffic safety laws. The investigation, which has been designated a "preliminary evaluation," is examining the software and its ability to avoid collisions with stationary objects and how well it detects and responds to "traffic safety control devices" like cones. The agency said Friday it has added (PDF) another nine incidents since the investigation was opened. Waymo reported some of these incidents. The others were discovered by regulators via public postings on social media and forums like Reddit, YouTube and X. The additional nine incidents include reports of Waymo robotaxis colliding with gates, utility poles, and parked vehicles, driving in the wrong lane with nearby oncoming traffic and into construction zones. The ODI said it's concerned the robotaxis "exhibiting such unexpected driving behaviors may increase the risk of crash, property damage, and injury." The agency said that while it's not aware of any injuries from these incidents, several involved collisions with visible objects that "a competent driver would be expected to avoid." The agency also expressed concern that some of these occurred near pedestrians. NHTSA has given Waymo until June 11 to respond to a series of questions regarding the investigation.

An anonymous reader quotes a report from The Guardian: Hopes that replacement fuels for airplanes will slash carbon pollution are misguided and support for these alternatives could even worsen the climate crisis, a new report has warned. There is currently "no realistic or scalable alternative" to standard kerosene-based jet fuels, and touted "sustainable aviation fuels" are well off track to replace them in a timeframe needed to avert dangerous climate change, despite public subsidies, the report by the Institute for Policy Studies, a progressive thinktank, found. "While there are kernels of possibility, we should bring a high level of skepticism to the claims that alternative fuels will be a timely substitute for kerosene-based jet fuels," the report said. [...] In the U.S., Joe Biden's administration has set a goal for 3 billion gallons of sustainable aviation fuel, which is made from non-petroleum sources such as food waste, woody biomass and other feedstocks, to be produced by 2030, which it said will cut aviation's planet-heating emissions by 20%. [...] Burning sustainable aviation fuels still emits some carbon dioxide, while the land use changes needed to produce the fuels can also lead to increased pollution. Ethanol biofuel, made from corn, is used in these fuels, and meeting the Biden administration's production goal, the report found, would require 114m acres of corn in the U.S., about a 20% increase in current land area given over to to the crop. In the UK, meanwhile, 50% of all agricultural land will have to be given up to sustain current flight passenger levels if jet fuel was entirely replaced. "Agricultural land use changes could threaten global food security as well as nature-based carbon sequestration solutions such as the preservation of forests and wetlands," the report states. "As such, SAF production may actively undermine the Paris agreement goal of achieving greatly reduced emissions by 2050." Chuck Collins, co-author of the report, said: "To bring these fuels to the scale needed would require massive subsidies, the trade-offs would be unacceptable and would take resources aware from more urgent decarbonization priorities." "It's a huge greenwashing exercise by the aviation industry. It's magical thinking that they will be able to do this." Phil Ansell, director of the Center for Sustainable Aviation at the University of Illinois, added: "There's an underappreciation of how big the energy problem is for aviation. We are still many years away from zero pollution flights. But it's true that the industry has been slow to pick things up. We are now trying to find solutions, but we are working at this problem and realizing it's a lot harder than we thought. We are late to the game. We are in the dark ages in terms of sustainability, compared to other sectors."

Hybrid and electric cars are more likely to hit pedestrians than petrol or diesel vehicles, due to their quieter engines that make them harder for pedestrians to hear. Other contributing factors include the tendency for drivers of electric cars to be younger and less experienced, and the vehicles' heavier weight and swift acceleration, increasing stopping distances. The Guardian reports: Data from 32 billion miles of battery-powered car travel and 3 trillion miles of petrol and diesel car trips showed that mile-for-mile electric and hybrid cars were twice as likely to hit pedestrians than fossil fuel-powered cars, and three times more likely to do so in urban areas. "Electric cars are a hazard to pedestrians because they are less likely to be heard than petrol or diesel cars," said Phil Edwards, first author on the study and professor of epidemiology and statistics at the London School of Hygiene & Tropical Medicine. "The government needs to mitigate these risks if they are going to phase out the sale of petrol and diesel cars." "If you're moving to an electric car, remember it's a new kind of vehicle," Edwards added. "They are much quieter than the old-fashioned cars, and pedestrians have learned to navigate roads by listening for traffic. Drivers of these vehicles need to be extra cautious." Most vehicles on the road are petrol or diesel and these were involved in three-quarters of pedestrian collisions. But for the same distance travelled, battery-powered cars were more dangerous. The average annual pedestrian casualty rate per 100m miles travelled was 5.16 for electric and hybrid cars compared with 2.4 for petrol and diesel cars, according to the study in the Journal of Epidemiology and Community Health. In rural settings, battery-powered cars were no more dangerous than petrol or diesel, but in towns and cities they were three times more likely to collide with pedestrians, the researchers found. Since July 2019, all new hybrid and electric vehicles sold in Europe have been required to have an acoustic vehicle alerting system that emits sound when the car is travelling slowly, but there are hundreds of thousands of electric cars on the road without the devices. "If government made sure these systems were installed in all electric vehicles and retrofitted them to older electric cars, that would be a good start," Edwards said, adding that the Green Cross Code also "probably needs updating."

"Last week, we reported on a customer who was charged $277 for gasoline his rented Tesla couldn't have possibly used," writes the automotive blog The Drive. "And now, we've heard from other Hertz customers who say they've been charged even more." Hertz caught attention last week for how it handled a customer whom it had charged a "Skip the Pump" fee, which allows renters to pay a premium for Hertz to refill the tank for them. But of course, this customer's rented Tesla Model 3 didn't use gas — it draws power from a battery — and Hertz has a separate, flat fee for EV recharges. Nevertheless, the customer was charged $277.39 despite returning the car with the exact same charge they left with, and Hertz refused to refund it until after our story ran. It's no isolated incident either, as other customers have written in to inform us that it happened to them, too.... Evan Froehlich returned the rental at 21 percent charge, expecting to pay a flat $25 recharge fee. (It's ordinarily $35, but Hertz's loyalty program discounts it.) To Froehlich's surprise, he was hit with a $340.97 "Skip the Pump" fee, which can be applied after returning a car if it's not requested beforehand. He says Hertz's customer service was difficult to reach, and that it took making a ruckus on social media to get Hertz's attention. In the end, a Hertz representative was able to review the charge and have it reversed.... A March 2023 Facebook post documenting a similar case indicates this has been happening for more than a year. After renting a Tesla Model 3, another customer even got a $475.19 "fuel charge," according to the article — in addition to a $25 charging fee: They also faced a $125.01 "rebill" for using the Supercharger network during their rental, which other Hertz customers have expressed surprise and frustration with. Charging costs can vary, but a 75-percent charge from a Supercharger will often cost in the region of just $15.

The thinktank InfluenceMap produces "data-driven analysis on how business and finance are impacting the climate crisis." Their web site says their newest report documents "How automaker lobbying threatens the global transition to electric vehicles." This report analyses the climate policy engagement strategies of fifteen of the largest global automakers in seven key regions (Australia, EU, Japan, India, South Korea, UK, US). It shows how even in countries where major climate legislation has recently passed, such as the US and Australia, the ambition of these policies has been weakened due to industry pressure. All fifteen automakers, except Tesla, have actively advocated against at least one policy promoting electric vehicles. Ten of the fifteen showed a particularly high intensity of negative engagement and scored a final grade of D or D+ by InfluenceMap's methodology. Toyota is the lowest-scoring company in this analysis, driving opposition to climate regulations promoting battery electric vehicles in multiple regions, including the US, Australia and UK. Of all automakers analyzed, only Tesla (scoring B) is found to have positive climate advocacy aligned with science-based policy. CleanTechnica writes that Toyota "led on hybrid vehicles (and still does), so it's actually not surprising that it has been opposed to the next stage of climate-cutting auto evolution — it's clinging on to its lead rather than continuing to innovate for a new era." More from InfluenceMap: Only three of fifteen companies — Tesla, Mercedes Benz and BMW — are forecast to produce enough electric vehicles by 2030 to meet the International Energy Agency's updated 1.5 degreesC pathway of 66% electric vehicle (battery electric, fuel cell and plug-in hybrids) sales according to InfluenceMap's independent analysis of industry-standard data from February 2024. Current industry forecasts analyzed for this report show automaker production will reach only 53% electric vehicles in 2030. Transport is the third-largest source of greenhouse gas emissions globally, and road transport is failing to decarbonize at anywhere near the rate of many other industries. InfluenceMap's report also finds that Japanese automakers are the least prepared for an electric vehicle transition and are engaging the hardest against it. "InfluenceMap highlights that these anti-EV efforts in the industry are often coming from industry associations rather than coming directly from automakers, shielding them a bit from inevitable public backlash," writes CleanTechnica. "Every automaker included in the study except Tesla remains a member of at least two of these groups," InfluenceMap reports, "with most automakers a member of at least five."

An anonymous reader shared this report from Automotive News: Automotive News recently reported that eight automakers sent vehicle location data to police without a court order or warrant. The eight companies told senators that they provide police with data when subpoenaed, getting a rise from several officials. BMW, Kia, Mazda, Mercedes-Benz, Nissan, Subaru, Toyota, and Volkswagen presented their responses to lawmakers. Senators Ron Wyden from Oregon and Ed Markey from Massachusetts penned a letter to the Federal Trade Commission, urging investigative action. "Automakers have not only kept consumers in the dark regarding their actual practices, but multiple companies misled consumers for over a decade by failing to honor the industry's own voluntary privacy principles," they wrote. Ten years ago, all of those companies agreed to the Consumer Privacy Protection Principles, a voluntary code that said automakers would only provide data with a warrant or order issued by a court. Subpoenas, on the other hand, only require approval from law enforcement. Though it wasn't part of the eight automakers' response, General Motors has a class-action suit on its hands, claiming that it shared data with LexisNexis Risk Solutions, a company that provides insurers with information to set rates. The article notes that the lawmakers praised Honda, Ford, GM, Tesla, and Stellantis for requiring warrants, "except in the case of emergencies or with customer consent."

Volkswagen has walked away from talks with Renault to jointly develop an affordable electric version of the Twingo car, Reuters reported Friday, citing sources familiar with the situation, in a setback for the EU carmakers' efforts to fend off Chinese rivals. From the report: The collapse of negotiations could mean the German carmaker may have to go it alone in developing its own affordable electric vehicle (EV). Renault will continue designing its electric Twingo, scheduled to hit the market in 2026. Both had hoped that sharing the work would cut costs that represent a key hurdle for European carmakers in the face of cheaper cars from China. Volkswagen broke off discussions mainly because Renault had wanted to build the car in one of its plants at a time when VW is seeking to fully utilise its European production network, one of the sources said.

An anonymous reader quotes a report from The Verge: Airbus Helicopters showcased an experimental half-plane, half-helicopter on Wednesday in a quest for speed as competition heats up to define the rotorcraft of the future. The $217 million Racer is a one-off demonstrator model combining traditional overhead rotors with two forward-facing propellors in a bid to combine stability and speed, shortening response times for critical missions like search-and-rescue. "There are missions where the quickest possible access to the zone is vital. We often talk about the 'golden hour'," Airbus Helicopters CEO Bruno Even told Reuters, referring to the window considered most critical for providing medical attention. Such designs could also be offered for military developments as NATO conducts a major study into next-generation helicraft, though much depends on how its planners define future needs. [...] Racer's public debut came months after Italy's Leonardo and U.S. manufacturer Bell agreed to co-operate on the next generation of tilt-rotor technology, which replaces a helicopter's trademark overhead blades altogether. Leonardo is also leading a separate project to develop the next generation of tilt-rotors for civil use. Its AW609 is the sole existing civil design, but has yet to be certified. Proponents of the tilt-rotor, which relies on swiveling side-mounted rotors 90 degrees to go up and then forwards, say it permits higher speed and range that are suited to military missions. Critics say the tilt mechanism reaches higher speeds only at the expense of higher complexity and maintenance costs. Airbus said the Racer will fly at 220 knots (400 km/hour) compared with traditional helicopter speeds closer to 140 knots. Bell says its V-280 Valor tilt-rotor design, recently picked by the Pentagon, will reach a cruise speed of 280 knots. Watch: Racer - Inside the high speed demonstrator (YouTube)

An anonymous reader quotes a report from Ars Technica: Crashing into parked cars, drifting over into oncoming traffic, intruding into construction zones -- all this "unexpected behavior" from Waymo's self-driving vehicles may be violating traffic laws, the US National Highway Traffic Safety Administration (NHTSA) said (PDF) Monday. To better understand Waymo's potential safety risks, NHTSA's Office of Defects Investigation (ODI) is now looking into 22 incident reports involving cars equipped with Waymo's fifth-generation automated driving system. Seventeen incidents involved collisions, but none involved injuries. Some of the reports came directly from Waymo, while others "were identified based on publicly available reports," NHTSA said. The reports document single-party crashes into "stationary and semi-stationary objects such as gates and chains" as well as instances in which Waymo cars "appeared to disobey traffic safety control devices." The ODI plans to compare notes between incidents to decide if Waymo cars pose a safety risk or require updates to prevent malfunctioning. There is already evidence from the ODI's initial evaluation showing that Waymo's automated driving systems (ADS) were either "engaged throughout the incident" or abruptly "disengaged in the moments just before an incident occurred," NHTSA said. The probe is the first step before NHTSA can issue a potential recall, Reuters reported. A Waymo spokesperson said the company currently serves "over 50,000 weekly trips for our riders in some of the most challenging and complex environments." When a collision occurs, Waymo reviews each case and continually updates the ADS software to enhance performance. "We are proud of our performance and safety record over tens of millions of autonomous miles driven, as well as our demonstrated commitment to safety transparency," Waymo's spokesperson said, confirming that Waymo would "continue to work" with the ODI to enhance ADS safety.

Cruise's autonomous vehicles have resumed operation in Phoenix, Arizona, following an incident in San Francisco last October where a driverless vehicle dragged a pedestrian. The Verge reports: Cruise spokesperson Tiffany Testo said the company is deploying only two autonomous vehicles with safety drivers behind the wheel. In addition, the company has eight manually driven vehicles in the city. Eventually, the service area will "gradually expand" to include Scottsdale, Paradise Valley, Tempe, Mesa, Gilbert, and Chandler -- "measured against predetermined safety benchmarks." Cruise's slow return to the road is noteworthy, given the huge hurdles facing the company in the wake of the October incident. Regulators accused the company of misleading them about the nature and severity of the incident, in which a pedestrian was dragged over 20 feet by a driverless Cruise after first being struck by a hit-and-run driver. Several top executives have since left the company, including founder and CEO Kyle Vogt, and around a quarter of employees were laid off. GM has said it will reduce its spending on Cruise. And an outside report found evidence that a culture of antagonism toward regulators contributed to many of the failings.

"Researchers are exploring ways to use features in modern cars, such as GPS, to make traffic safer and more efficient," reports the Associated Press. "Eventually, the upgrades could do away entirely with the red, yellow and green lights of today, ceding control to driverless cars." Among those reimagining traffic flows is a team at North Carolina State University led by Ali Hajbabaie, an associate engineering professor. Rather than doing away with today's traffic signals, Hajbabaie suggests adding a fourth light, perhaps a white one, to indicate when there are enough autonomous vehicles on the road to take charge and lead the way. "When we get to the intersection, we stop if it's red and we go if it's green," said Hajbabaie, whose team used model cars small enough to hold. "But if the white light is active, you just follow the vehicle in front of you." He points out that this approach could be years aways, since it requires self-driving capability in 40% to 50% of the cars on the road. But the article notes another approach which could happen sooner, talking to Henry Liu, a civil engineering professor who is leading ">a study through the University of Michigan: They conducted a pilot program in the Detroit suburb of Birmingham using insights from the speed and location data found in General Motors vehicles to alter the timing of that city's traffic lights. The researchers recently landed a U.S. Department of Transportation grant under the bipartisan infrastructure law to test how to make the changes in real time... Liu, who has been leading the Michigan research, said even with as little as 6% of the vehicles on Birmingham's streets connected to the GM system, they provide enough data to adjust the timing of the traffic lights to smooth the flow... "The beauty of this is you don't have to do anything to the infrastructure," Liu said. "The data is not coming from the infrastructure. It's coming from the car companies." Danielle Deneau, director of traffic safety at the Road Commission in Oakland County, Michigan, said the initial data in Birmingham only adjusted the timing of green lights by a few seconds, but it was still enough to reduce congestion. "Even bigger changes could be in store under the new grant-funded research, which would automate the traffic lights in a yet-to-be announced location in the county."

An anonymous reader shared this report from PetaPixel: A photographer and content creator has set the world record for the fastest drone flight after his custom-made aircraft achieved a staggering 298.47 miles per hour (480.2 kilometers per hour). Guinness confirmed the record noting that Luke Maximo Bell and his father Mike achieved the "fastest ground speed by a battery-powered remote-controlled (RC) quadcopter." Luke, who has previously turned his GoPro into a tennis ball, describes it as the most "frustrating and difficult project" he has ever worked on after months of working on prototypes that frequently caught fire. From the very first battery tests for the drone that Luke calls Peregrine 2, there were small fires as it struggled to cope with the massive amount of current which caused it to heat up to over 266 degrees Fahrenheit (130 degrees Celsius). The motor wires also burst into flames during full load testing causing Luke and Mike to use thicker ones so they didn't fail... After 3D-printing the final model and assembling all the parts, Luke took it for a maiden flight which immediately resulted in yet another fire. This setback made Bell almost quit the project but he decided to remake all the parts and try again — which also ended in fire. This second catastrophe prompted Luke and his Dad to "completely redesign the whole drone body." It meant weeks of work as the new prototype was once again tested, 3D-printed, and bolted together.

Thursday the BBC reported: Plane bodies made by Boeing's largest supplier regularly left the factory with serious defects, according to a former quality inspector at the firm. Santiago Paredes who worked for Spirit AeroSystems in Kansas, told the BBC he often found up to 200 defects on parts being readied for shipping to Boeing. He was nicknamed "showstopper" for slowing down production when he tried to tackle his concerns, he claimed. Spirit said it "strongly disagree[d]" with the allegations. "We are vigorously defending against his claims," said a spokesperson for Spirit, which remains Boeing's largest supplier. Mr Paredes made the allegations against Spirit in an exclusive interview with the BBC and the American network CBS, in which he described what he said he experienced while working at the firm between 2010 and 2022... "I was finding a lot of missing fasteners, a lot of bent parts, sometimes even missing parts...." Mr Paredes told the BBC that some of the defects he identified while at Spirit were minor — but others were more serious. He also claimed he was put under pressure to be less rigorous... He now maintains he would be reluctant to fly on a 737 Max, in case it still carried flaws that originated in the Wichita factory. "I'd never met a lot of people who were scared of flying until I worked at Spirit," he said. "And then, being at Spirit, I met a lot of people who were afraid of flying — because they saw how they were building the fuselages." "If quality mattered, I would still be at Spirit," Paredes told CBS News, speaking publicly for the first time. CBS News spoke with several current and former Spirit AeroSystems employees and reviewed photos of dented fuselages, missing fasteners and even a wrench they say was left behind in a supposedly ready-to-deliver component. Paredes said Boeing knew for years Spirit was delivering defective fuselages. It could be just a coincidence, but the same day, the Associated Press ran story with this headline. "Boeing plane carrying 85 people catches fire and skids off the runway in Senegal, injuring 10." It was the third incident involving a Boeing airplane this week. Also on Thursday, 190 people were safely evacuated from a plane in Turkey after one of its tires burst during landing at a southern airport, Turkey's transportation ministry said.

An anonymous reader quotes a report from Ars Technica: There's a fundamental flaw in current car safety tech: It's limited to line of sight. Or, perhaps, line of "sensing" is more accurate, because the way cameras and lidar work is to inspect the perimeter of a vehicle and use predictive algorithms to understand the motion of an object in relation to the motion of the vehicle itself. Which is good, because as carmakers have added elements such as pedestrian and cyclist detection, they're trying to prevent drivers from hurting the most vulnerable road users. And unfortunately this is necessary, because even though 2023 saw a slight reduction in drivers striking cyclists and pedestrians, according to the most recent data from the Governor's Highway Safety Association, since 2019 pedestrian fatalities are still up 14 percent -- and cyclist deaths are up 50 percent since 2010. That doesn't mean lidar and cameras have "failed," but because they rely on what the sensors can pick up, they cannot necessarily ID hazards (and alert drivers) as quickly as we need them to, particularly if that's a cyclist in your lane 300 feet down the road, just over the next rise. Yes, current sensing works well now with figuring out the pace of a traffic jam, and automatic emergency braking can step in to stop your car if you fail to. But for non-automotive obstacles, they're still limited. For that, we need better tech, which is emerging and is called Connected Vehicle to Everything (C-V2X). The idea isn't that complicated. Boiled down, it's a chipset that operates on a portion of the cellular bandwidth, and vehicles with this tech embedded (say in an e-bike or car) monitor anything with a C-V2X chip as well as broadcast their own location at a pulse of 10 times a second. This precision location system would then warn a driver of a cyclist on the road ahead, even beyond line of sight, and in an emergency -- possibly because a cyclist was right in a car's path -- could prevent a collision. [W]ith C-V2X, you don't need Verizon or ATT or anything like that," explains Audi's Kamal Kapadia. Because it isn't using the cellular network -- it's using a portion of cellular bandwidth to allow direct object, or vehicle-to-vehicle, communication. Audi has been working on C-V2X for nearly a decade, and it's part of a group in the US called the Coalition for Cyclist Safety, which also includes suppliers like Bosch, a tech startup in the space called Spoke Safety, and bike brands such as massive Trek, parts supplier Shimano, more niche bikemakers like Switzerland's Stromer, as well as mega telco suppliers and networks such as Qualcomm, Deutsche Telekom, and TELUS. [...] Mio Suzuki is Trek Bicycle's director of embedded systems, "and we are exploring all sorts of safety," she says. For instance, Trek recently introduced its own radar tail light, which warns riders of a car approaching rapidly -- Garmin has had similar systems for several years. But Suzuki is intrigued by C-V2X because it offers more advanced warning than rear-facing radar. "And unlike cars, we have a very vulnerable road user so we need to augment our senses and the rider's awareness of the riding environment, because we don't have a big metal shield around us." What Suzuki envisions this direct communication might enable is an e-bike where the rider has a display that would warn a rider "of an imminent danger that's approaching; a car might be coming from the side, but the view of the car is obstructed by a building, so the rider can't see." Franz Reindl is CTO of Stromer, a high-end Swiss brand that only makes e-bikes with very top tech, including ABS brakes. Reindl says they're also studying C-V2X. "Safety is one of our biggest promises, and we need to do everything we can with products and technologies to make it more safe for customers." Right now, only Audi and the VW Group have openly talked about using the tech. "Trek's Suzuki thinks that together, the Coalition and so many bike brands within it do have a strong voice," reports Ars. "She also envisions municipalities deploying the technology, especially around work crews and EMS, which should build broader momentum and pressure on automakers."
