An AI test pilot has successfully flown a jet fighter in dogfights against human opponents. It's the latest development for DARPA's Air Combat Evaluation program, which is trying to develop aerospace AI agents that can be trusted to perform safely.

Human test pilots have a bit of a reputation thanks to popular culture—from The Right Stuff to Top Gun: Maverick , the profession has been portrayed as a place for loose cannons with a desire to go fast and break the rules. The reality is pretty far from that these days, especially where DARPA is concerned.

The agency instead wants a machine learning agent that can safely fly a real aircraft autonomously, with no violations of training rules. After all, neural networks have their own reputation—at this point well-earned—for finding ways to exploit situations that hadn't occurred to humans, And the consequences when controlling a real jet fighter can be a lot more severe than just testing in silico .

On Monday, we learned that Tesla had suspended customer deliveries of its stainless steel-clad electric pickup truck. Now, the automaker has issued a recall for all the Cybertrucks in customer hands—nearly 4,000 of them—in order to fix a problem with the accelerator pedal. It has come at an inconvenient time for Tesla, which is laying off more than 10 percent of its workforce due to shrinking sales even as CEO Elon Musk asks for an extra $55.8 billion in compensation.

The problem, which affects all 3,878 Cybertrucks delivered so far, has to do with the EV's accelerator pedal. Tesla has fitted this with a metal-finish cover to match the brushed metal appearance of the truck itself— no word on whether the pedals rust, too —but it says that at some point , "an unapproved change introduced lubricant (soap) to aid in the component assembly of the pad onto the accelerator pedal. Residual lubricant reduced the retention of the pad to the pedal."

Thanks to the profile of the Cybertruck's under dash, if the pedal cover becomes partially detached it can slide up and become trapped in place, wedging the pedal down and unleashing all of the Cybertruck's substantial power—the dual-motor truck boasts 600 hp (447 kW) and can reach 60 mph (98 km/h) in just over four seconds.

The United States has won an important battle in its war to keep low-cost Chinese electric vehicles from American car buyers. Today, Reuters reports that the Mexican federal government has responded to pressure from the US and will not offer incentives to Chinese automakers, like BYD, that are looking to establish North American manufacturing operations.

BYD last met with Mexican officials in January, according to Reuters, where it learned that Chinese automakers would not be offered tax breaks or cheap land to build factories.

Until now, Mexico has offered foreign automakers generous subsidies that have made the country a cheap place to build cars . Added to that, the United States-Mexico-Canada Free Trade Agreement also makes Mexico desirable for ease of access to the US market, and Chinese automotive part suppliers have flocked to the country in recent years.

Mercedes-Benz's E Class badge possesses a lot of canon. When asked to picture a '90s-or-newer Mercedes full-size sedan, it's hard not to conjure up mental snapshots of W124-and-up generations schlepping around well-heeled suburban communities. I bet a lot of folks also picture the taxi lineup outside any German train station, too.

Well, at least I do. But I'm not talking about envisioning surly Munich cabbies but rather the faithful four-doors they putter around in. A lot of them are E Classes, which further proves that the cars have always been quintessential Mercedes luxury workhorses.

The brand-new 2024 E 350 4Matic, with its thrifty turbo-four powerplant, might have the most direct lineage in the US market to those cream-colored rickety diesels. It's easy on fuel for its size and ready to soak up all the miles across both traffic-ridden cityscapes and high-speed stretches of highway. And with its expansive suite of tech and mild hybrid propulsion, it's an overall great next chapter for the badge.

This week, the National Highway Traffic Safety Administration decided to expand an ongoing investigation into the alarming tendency of some modern Hondas to inappropriately trigger their automatic emergency braking systems. Studies have shown that automatic emergency braking systems have reduced road deaths in the US , Europe , and China , but so-called phantom braking problems have dogged systems from both Tesla and Honda.

We first learned of the problem in 2022 , when NHTSA opened a preliminary investigation into the matter, based on 278 complaints. Now, NHTSA's Office of Defects Investigation has received 1,294 complaints from drivers of Honda CR-Vs (model years 2017–2022) and Honda Accords (model years 2018–2022), all claiming that their Hondas' automatic emergency braking system slammed on the brakes with no apparent obstruction in the way.

Honda says it's aware of even more cases—1,991 in all, and NHTSA says that, when it takes out cases where multiple reports affect the same vehicle, it knows of 2,976 reports of inadvertent automatic emergency braking, with 93 injury reports and 47 crashes to date.

Google Maps is making itself friendlier for electric vehicles. A couple of years ago it added the option to select different powertrain types when calculating a route—gas, hybrid, electric, and so on. Lower-energy routes with fewer hills are helpful for electric vehicles, but mostly what EV drivers on unfamiliar terrain really want to know about are the chargers: Where are they, how fast are they, and do they work? Soon, that critical information will be available to Google Maps users via a new update.

Live charger status is usually available from the on-board navigation system built into an EV. Better yet, those native nav systems invariably talk to the powertrain, so they know how much state of charge is currently in the battery and how much to expect upon arrival. Add in real-time status on chargers—how many are working, how many are available—and it's not hard to see why plenty of EV drivers stick with the built-in system.

But for some EVs, that built-in system is Google Maps, including EVs from Ford, Honda, General Motors , Volvo, Polestar, and soon even Porsche . These will be the first devices to receive the update, Google says, which will roll out globally in the coming months. After the connected cars, smartphones will be next.

Right now, the electric vehicle ownership experience is optimized for the owner who lives in a single-family home. A level 2 home AC charger costs a few hundred dollars, and with a garage or carport, an EV that gets plugged in each night is an EV that starts each day with a 100 percent charged battery pack. Plenty of Ars readers have told us that a 120 V outlet even works for their needs, although perhaps better for Chevy Bolt-sized batteries rather than a Hummer EV.

However, about a third of Americans live in large multifamily developments, often in cities that stand to benefit the most from a switch to electrification. And electrifying the parking lots of existing developments is often easier said than done. Some developments will allow individuals to install their own dedicated charger, and newly built developments may even have planned ahead and put conduits in place already.

For many others, the parking spaces will be owned by the condo association or co-op, complicating the idea of giving each EV driver their own plug. Here, shared solutions make more sense, perhaps starting with one or two shared level 2 chargers as a pilot—often this won't even require extra work to the electrical panel. Costs are a little higher than for a home level 2 charger—between $7,500–$15,000 per charger, perhaps.

Times are starting to get tough for Tesla. The electric vehicle automaker had been riding high, with quarter after quarter of successive growth and plenty of profits in the process. But lately, that success has mostly been due to a series of price cuts meant to tempt customers to buy into an aging lineup . This March, the company reported its first quarterly decline since 2020.

Now, it plans to lay off more than 10 percent of its workforce, according to an internal memo seen by Reuters .

"As we prepare the company for our next phase of growth, it is extremely important to look at every aspect of the company for cost reductions and increasing productivity," Tesla CEO Elon Musk told employees in the memo.

Tesla's troubled Cybertruck appears to have hit yet another speed bump. Over the weekend, dozens of waiting customers reported that their impending deliveries had been canceled due to "an unexpected delay regarding the preparation of your vehicle."

Tesla has not announced an official stop sale or recall, and as of now, the reason for the suspended deliveries is unknown. But it's possible the electric pickup truck has a problem with its accelerator.

Tesla has been accused of making cars that have sudden unintended acceleration problems. In 2017, the company was the subject of a class-action lawsuit based on at least 23 accounts of Tesla Models S and X suffering from this problem. Tesla vehemently denied any such problem, and in 2020, the National Highway Traffic Safety Administration declined to investigate.
