New York City's subway system continues to operate largely on analog signal technology installed nearly a century ago, with 85% of the network still relying on mechanical equipment that requires constant human intervention. The outdated system causes approximately 4,000 train delays monthly and represents a technological time capsule in America's largest mass transit system.

Deep inside Brooklyn's Hoyt-Schermerhorn station, transit worker Dyanesha Pryor operates a hulking machine the size of a grand piano by manipulating 24 metal levers that control nearby trains. Each command requires a precise sequence of movements, punctuated by metallic clanking as levers slam into place. When Pryor needs to step away, even for a bathroom break, express service must be rerouted until she returns, forcing all trains onto local tracks.

The antiquated "fixed block" signaling divides tracks into approximately 1,000-foot sections. When a train occupies a block, it cuts off electrical current, providing only a general position rather than precise location data. This imprecision requires maintaining buffer zones between trains, significantly limiting capacity as ridership has grown. Maintenance challenges are also piling up, writes the New York Times. Hundreds of cloth-wrapped wires -- rather than modern rubber insulation -- fill back rooms and are prone to failure. When equipment breaks, replacements often must be custom-made in MTA workshops, as many components have been discontinued for decades.

The Metropolitan Transportation Authority has begun replacing this system with communications-based train control (C.B.T.C.), which uses computers and wireless technology to monitor trains' exact locations. Routes already converted to C.B.T.C., including the L line (2006) and 7 line (2018), consistently show the best on-time performance. However, the $25 million per-mile upgrade program faces uncertain funding after the Trump administration threatened to kill New York's congestion pricing plan, which would provide $3 billion for signal modernization.

New submitter LDA6502 writes: The Republican chairman of the House Transportation and Infrastructure Committee is proposing a new annual federal vehicle registration fee of $200 for full EVs, $100 for hybrid EVs, and $20 for combustion vehicles. The tax would be tied to inflation, would be collected by the states, and would expire in 2035. Critics of the proposal note that it could result in low mileage EVs paying a far higher tax rate than heavy ICE trucks and SUVs. Ars Technica notes that the bill "exempts commercial vehicles, which should see a rush from tax avoiders to register their vehicles under their businesses [...]." Farm vehicles will also be exempt from the tax.

"The Eno Center for Transportation calculates that this new tax will contribute an extra $110 billion to the highway Trust Fund by 2035 but that cuts to other taxes and more spending mean that the fund will still be $222 billion short of its commitments -- assuming that this added fee doesn't further dampen EV adoption in the U.S., that is."

NIST: Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. This month, NIST researchers published a journal article establishing NIST-F4 as one of the world's most accurate timekeepers. NIST has also submitted the clock for acceptance as a primary frequency standard by the International Bureau of Weights and Measures (BIPM), the body that oversees the world's time.

NIST-F4 measures an unchanging frequency in the heart of cesium atoms, the internationally agreed-upon basis for defining the second since 1967. The clock is based on a "fountain" design that represents the gold standard of accuracy in timekeeping. NIST-F4 ticks at such a steady rate that if it had started running 100 million years ago, when dinosaurs roamed, it would be off by less than a second today.

By joining a small group of similarly elite time pieces run by just 10 countries around the world, NIST-F4 makes the foundation of global time more stable and secure. At the same time, it is helping to steer the clocks NIST uses to keep official U.S. time. Distributed via radio and the internet, official U.S. time is critical for telecommunications and transportation systems, financial trading platforms, data center operations and more.

Widespread power outages were reported Monday in parts of Spain, Portugal and France, affecting critical infrastructure like airports and causing transportation disruptions. From a report: "The interruption was due to a problem in the European electricity grid," E-Redes, the national energy supplier of Portugal, said in a statement. In addition to Portugal, it said, "The blackout also affected regions of Spain and France, due to faults in very high voltage lines."

E-Redes said that the outage was widespread across Spain, with outages in Catalonia, Andalusia, Aragon, Navarre, the Basque Country, Castile and Leon, Extremadura and Murcia. In France, the Portuguese energy supplier said, "the Basque Coast and the Burgundy region also experienced power cuts."

Spain's national power company, Red Electricia, said in a post on X that it had restored some power in the north and south of the peninsula. The cause of the outages was not immediately clear. But the effects of the disruption were felt in cities across the region.

Pete Koomen, a Y Combinator partner, argues that current AI applications often fail by unnecessarily constraining their underlying models, much like early automobiles that mimicked horse-drawn carriages rather than reimagining transportation. In his detailed critique, Koomen uses Gmail's AI email draft feature as a prime example. The tool generates formal, generic emails that don't match users' actual writing styles, often producing drafts longer than what users would naturally write.

The critical flaw, according to Koomen, is that users cannot customize the system prompt -- the instructions that tell the AI how to behave. "When an LLM agent is acting on my behalf I should be allowed to teach it how to do that by editing the System Prompt," Koomen writes. Koomen suggests AI is actually better at reading and transforming text than generating it. His vision for truly useful AI email tools involves automating mundane work -- categorizing, prioritizing, and drafting contextual replies based on personalized rules -- rather than simply generating content from scratch. The essay argues that developers should build "agent builders" instead of agents, allowing users to teach AI systems their preferences and patterns.

The Trump administration introduced a new framework to expedite self-driving vehicle deployment by reducing regulatory hurdles, while maintaining mandatory safety incident reporting. NHTSA is also expanding its exemption program, allowing domestically produced autonomous vehicles lacking traditional safety controls to operate on U.S. roads. Reuters reports: The Trump administration said Thursday it aims to speed up the deployment of self-driving vehicles but will maintain rules requiring reporting of safety incidents involving advanced vehicles. U.S. Transportation Secretary Sean Duffy on Thursday released a new framework to boost autonomous vehicles. "This administration understands that we're in a race with China to out-innovate, and the stakes couldn't be higher," Duffy said. "Our new framework will slash red tape."

The National Highway Traffic Safety Administration said it will expand a program to exempt some self-driving vehicles from all safety requirements and will streamline but continue its requirement that vehicles equipped with certain advanced driver assistance systems or self-driving systems report safety incidents. NHTSA is expanding its Automated Vehicle Exemption Program to now include domestically produced vehicles that will allow companies to operate non-compliant imported vehicles on U.S. roads. It is currently only open to foreign assembled models.

The Federal Trade Commission filed suit against Uber on Monday, alleging the transportation giant violated federal consumer protection laws through deceptive billing and cancellation practices for its Uber One subscription service. According to the complaint, Uber violated both the FTC Act and the Restore Online Shoppers' Confidence Act by misleading consumers about subscription terms, charging users without consent, and implementing deliberately complicated cancellation processes.

"Americans are tired of getting signed up for unwanted subscriptions that seem impossible to cancel," FTC Chair Andrew Ferguson said in announcing the action. The $9.99 monthly service, launched in 2021, offers benefits including fee-free delivery and discounted rides.

China is banning automakers from using the terms "smart driving" and "autonomous driving" when they advertise driving assistance features, and it will tighten scrutiny of such technology upgrades. From a report: The mandate on vehicle advertising was delivered by the Ministry of Industry and Information Technology in its meeting with nearly 60 representatives from automakers on Wednesday, according to a transcript seen by Reuters and confirmed by one of the attendees. The move follows a fatal accident involving Xiaomi's best-selling SU7 sedan in March that triggered widespread concerns over vehicle safety.

The M.T.A. has unveiled on Wednesday a revamped New York City subway map -- the first major redesign in nearly 50 years. As reported by the New York Times, the map draws inspiration from the modernist but controversial 1972 Unimark version, prioritizing clarity over geographic precision. It's also a part of a broader effort to refresh the system's image amid calls for infrastructure upgrades and political tensions over transit funding and congestion pricing. From the report: The updated version blends elements of the Unimark design with a successor known to some as the Tauranac map, after John Tauranac, a well-regarded New York mapmaker. That design was led by the firm Michael Hertz Associates. The new map is already being displayed on digital monitors, and will be posted in subway cars and platforms over the next several weeks, the M.T.A. said.

For Janno Lieber, the authority's chairman, the occasion was also an opportunity to tie his ambitions for the system to a critical moment in its past. "This is a linchpin moment, like in 1979, when we started to fix the subway system," Mr. Lieber said, referring to the year before the M.T.A. debuted its first capital plan to upgrade the aging transit system. As then, the system is in dire need of new trains and infrastructure improvements. So far, the State Legislature has yet to fully fund the latest $68 billion plan.

The Unimark subway map released in 1972. The latest iteration of New York City's map takes cues from the design. Two of the biggest alterations address the legibility of transfer points at some of the busiest hubs and the depiction of the system's accessibility features, said Shanifah Rieara, the authority's chief customer officer. Mr. Lieber declined to say how much the redesign cost, but said it was paid for "entirely in house," without a stand-alone budget.

An anonymous reader quotes a report from Reuters: China's Xiaomi said on Tuesday that it was actively cooperating with police after a fatal accident involving a SU7 electric vehicle on March 29 and that it had handed over driving and system data. The incident marks the first major accident involving the SU7 sedan, which Xiaomi launched in March last year and since December has outsold Tesla's Model 3 on a monthly basis. Xiaomi's shares, which had risen by 34.8% year to date, closed down 5.5% on Wednesday, underperforming a 0.2% gain in the Hang Seng Tech index. Xiaomi did not disclose the number of casualties but said initial information showed the car was in the Navigate on Autopilot intelligent-assisted driving mode before the accident and was moving at 116 kph (72 mph).

A driver inside the car took over and tried to slow it down but then collided with a cement pole at a speed of 97 kph, Xiaomi said. The accident in Tongling in the eastern Chinese province of Anhui killed the driver and two passengers, Chinese financial publication Caixin reported on Tuesday citing friends of the victims. In a rundown of the data submitted to local police posted on a Weibo account of the company, Xiaomi said NOA issued a risk warning of obstacles ahead and its subsequent immediate takeover only happened seconds before the collision. Local media reported that the car caught fire after the collision. Xiaomi did not mention the fire in the statement. The report notes that the car was a "so-called standard version of the SU7, which has the less-advanced smart driving technology without LiDAR."

California has 11.3% of America's population — but bought 30% of America's new zero-emission vehicles. That's according to figures from the California Air Resources Board, which also reports 1 in 4 Californians have chosen a zero-emission car over a gas-powered one... for the last two years in a row.

But what about chargers? It turns out that California now has 48% more public and "shared" private EV chargers than the number of gasoline nozzles. (California has 178,000 public and "shared" private EV chargers, versus about 120,000 gas nozzles.) And beyond that public network, there's more than 700,000 Level 2 chargers installed in single-family California homes, according to the California Energy Commission.

Of the 178,000 public/"shared" private chargers, "Over 162,000 are Level 2 chargers," according to an announcement from the governor's office, while nearly 17,000 are fast chargers. (A chart shows a 41% jump in 2024 — though the EV news site Electrek notes that of the 73,537 chargers added in 2024, nearly 38,000 are newly installed, while the other 35,554 were already plugged in before 2024 but just recently identified.) California approved a $1.4 billion investment plan in December to expand zero-emission transportation infrastructure. The plan funds projects like the Fast Charge California Project, which has earmarked $55 million of funding to install DC fast chargers at businesses and publicly accessible locations.

"I've been dreaming of this moment for 20 years," says Aptera co-CEO Steve Fambro. Aptera's solar-powered electric car just drove 300 miles on a single charge.

"We're one step closer to a future where every journey is powered by the sun," Aptera says in their announcement.

"This go around, Aptera took to the highway for the first time ever..." writes the EV blog Electrek. "At one point, Aptera's video noted that its solar EV was pulling over 545 watts of solar input, even though it was overcast."

"Less time searching for chargers," Aptera says in their announcement, adding that their "production-intent" car proved "that a solar EV isn't just a concept for the future, but a real-world solution ready for the present" — while turning Route 66 into "a test bed for a vehicle built to thrive independently..." "The panoramic windshield gives you this incredible view of the landscape," Steve said [in a video accompanying the announcement], describing the drive. "It's like a big picture window into the future."

The final stretch took the team back into California, where they reflected on the journey, the data, and the excited reactions from drivers who caught a glimpse of the vehicle on the road. "Almost everyone we passed had their phones out filming us," Steve laughed. "It's clear that Aptera's design stops traffic — without needing to stop for a charge."
"I was struck by how normal this trip seemed, except for all the gawking from fellow travelers," writes long-time Slashdot reader AirHog. "Best of luck to Aptera to reach their funding and production goals this year for this remarkable vehicle."

They drove on highways to Lake Havasu, and then to California's Imperial Valley — starting in Flagstaff, Arizona on symbolic Route 66. It was 100 years ago that Route 66 was proposed to link Chicago and Los Angeles, which Fambro credits to a visionary who believed in "something bigger than the road itself — believing in what it could unlock for the world." "And they did it. Route 66 became one of the most iconic highways in America, proving that what once seemed improbable could become inevitable.

"I think about that alot with Aptera. We're building something people say can't be done. History shows us the boldest ideas, the ones that challenge that status quo are the ones that truly change the world.
They take their futuristic, tear-dropped shaped "Jetsons" car to a drive-through wildlife refuge named Bearizona. They stop at a general store for some beef jerky. "We're just having a fun time seeing all the sights."

"I've been dreaming of this moment for 20 years," says Aptera co-CEO Steve Fambro. "Driving in the most efficient vehicle on the road. Watching the sights go by. I got emotional just taking it all in." "This company. This idea. It's real. It's visceral. And I'm just so proud of each and every person who helped make this dream a reality.

"We have the chance to make a real change in how the world moves. The road hasn't been easy. It's been painful, difficult. And it's brought me to my breaking point sometimes. But being in this moment right now? I can say it's all been worth it...

"I feel we're at the forefront of something truly revolutionary. We're not fighting an uphill battle any more. We're standing at the edge of something incredible. Ready to break through.

"To all of you who supported us, my commitment is this. We're not stopping. We're moving forward with more energy and more passion than ever. The road ahead is an open highway. And the future is ours to shape."
To celebrate Aptera is holding a giveaway for a camping kit, a $100 gift card to their online store, and a free Aptera pre-order to a winner chosen at random from those who subscribe/watch/comment on their new video...

Automotive historian Dan Albert loves the "adorable tiny truck" he's driving. It's one of the small Japan-made "kei" pickups and minivans that "make up about a third of car sales in Japan." Americans can legally import older models for less than $10,000, and getting 40 miles per gallon they're "Cheap to buy and run... rugged, practical, no-frills machines — exactly what the American-built pickup truck used to be."

But unfortunately, kei buyers face "bureaucratic roadblocks that states like Massachusetts have erected to keep kei cars and trucks out of the hands of U.S. drivers." Several state departments of motor vehicles (DMVs) have balked at registering the imported machines, saying that they're too unsafe for American streets. Owners have responded with a righteous mix of good humor, lobbying and lawsuits... Kei trucks do not meet the Federal Motor Vehicle Safety Standards, or FMVSS — the highly specific rules US-market new cars must meet. But since 1988, the Imported Vehicle Safety Compliance Act has exempted vehicles that are at least 25 years old from these crash safety standards, allowing drivers to bring over vintage European and Asian market models...

Getting insurance coverage was the next barrier, as the company that had long been underwriting the Albert family's fleet also rejected me, forcing me to seek out a specialty "collector car" insurer. (I did eventually get regular coverage....) Maine, Rhode Island, New York, Pennsylvania, Georgia, Virginia, and Michigan also tightened their rules on registering small Japanese imports in recent years. The culprit, according to the auto enthusiast press, was the American Association of Motor Vehicle Administrators, the trade organization that serves as the lobbying and policy arm of DMVs across North America. Much of AAMVA's work involves integrating the databases of the 69 US and Canadian motor vehicle jurisdictions who are its members, so that a car stolen in one state can't be titled in another... The kei truck's regulatory troubles can be traced to a 2011 AAMVA report, "Best Practices Regarding Registration and Titling of Mini-Trucks," which called for outright bans and encouraged DMVs to lobby state legislatures to outlaw keis entirely.

The Insurance Institute of Highway Safety concurred, telling AAMVA that its recommendation did not go far enough: The IIHS said that keis should join the class of conveyances that the U.S. government calls Low Speed Vehicles, which are mechanically limited to 25 miles per hour or less and should be used only for short local trips on low-speed-limit roads because they can't protect occupants in the event of a collision with a regular vehicle... [But] By 2008, Japan's kei trucks did feature crumple zones and driver airbags in compliance with that country's safety standards...

Despite its name, the Imported Vehicle Safety Compliance Act that lets older cars into the US from overseas isn't really about safety: Car industry lobbyists secured passage of the law to protect dealer profits. Newer keis — which are banned — are safer and cleaner than the 25-year-old ones that can be imported now. (Battery-powered keis debuted in 2009.) But even mine has an airbag, front crumple zone, seatbelt pretensioners, and anti-lock brakes.
The article notes that kie fans have "a distinctly libertarian streak... Some owners I've talked to report forging titles, setting up shell companies in Montana and finding other means of skirting DMV rules."

Last week an Air France flight to the Caribbean had to turn around and return to Paris, reports the Washington Post, "after a passenger could not locate their cellphone."

Because of fears that an unattended cellphone could overheat — and because the passenger and crew couldn't find the phone — the Boeing 777 turned around off the coast of France "and returned to the airport, according to the flight-tracking service FlightAware. It landed back where it started a little more than two hours after taking off, with 375 passengers, 12 cabin crew and two pilots on board..." It was the airline's second Caribbean-bound flight to turn around because of a phone since early February as the aviation industry grapples with the risk of fires sparked by lithium batteries... Air France did not say where on the plane the phone was lost — or where it was ultimately located. "After checks by the maintenance teams, the device was found and the aircraft was able to take off again quickly," the airline said in an unsigned statement. "Air France regrets this situation and reminds that the safety of its customers and crew members is its absolute priority." The plane made it to Guadeloupe, a French overseas territory, about four hours later than scheduled...
The articles notes that U.S. air passengers "are required to keep vape pens and spare lithium batteries, such as portable chargers, in the cabin at all times, according to the Federal Aviation Administration. The items are not allowed in checked bags..."

The agency — which handles about 16.4 million flights per year — "says it is aware of 85 lithium battery air incidents involving smoke, fire or extreme heat last year."

An anonymous reader quotes a report from the Washington Post: Virginia is set to become the first state in the country to require some reckless drivers to put devices on their cars that make it impossible to drive too fast. D.C. passed similar legislation last year. Several other states, including Maryland, are considering joining them. It's an embrace of a technological solution to a human problem: Speeding contributes to more than 10,000 deaths a year. Under the Virginia legislation, a judge can decide to order drivers to install the speed limiters in their vehicles in lieu of taking away their driving privileges or sending them to jail. It takes effect in July 2026.

Del. Patrick A. Hope (D-Arlington) said various advocacy groups, including Mothers Against Drunk Driving and the National Safety Council, gave him the idea. He drove a car outfitted with the technology and was impressed. "It was easy to use, and once you're engaged it's impossible to go over the speed limit," he said. "It will make our streets safer." He thinks the device is preferable to suspending drivers' licenses, a punishment that people frequently ignore because they have no other way of getting to work or the store or taking their children to school. It's an approach similar to using an interlock device that requires a person convicted of drunken driving to pass a Breathalyzer test to start their car.

Hope wanted anyone convicted of reckless driving after going 100 mph or more to be required to use a limiter for two to six months, but Gov. Glenn Youngkin (R) struck that part of the bill, leaving all use of the limiting technology up to the state courts. Hope expressed concern about the governor's amendment but will urge the General Assembly to accept it, as the legislature typically does when the bill's sponsor signals support. Drivers must pay for the speed limiters themselves. (As in D.C., indigent defendants are exempt from paying.) The limiters won't be used in Virginia on commercial vehicles. Attempting to evade the speed limiter by tampering with it or driving a different car is a misdemeanor punishable by up to a year in jail.

Transport for London will ban most e-bikes across its network from March 31 amid growing safety concerns over battery fires, the transport authority announced on Wednesday. The ban, covering London Underground, Overground, Elizabeth Line and DLR trains, exempts only folding e-bikes, which are considered less likely to have been modified and pose a reduced safety risk.

TfL implemented the measure following union strike threats after several incidents, including an e-bike that exploded into flames at Rayners Lane Underground platform last month. The train drivers' union Aslef said the incident could have caused mass casualties.

"China is considering trying to blunt greater U.S. tariffs and other trade barriers," reports the Wall Street Journal, "by offering to curb the quantity of certain goods exported to the U.S., according to advisers to the Chinese government." Tokyo's adoption of so-called voluntary export restraints, or VERs, to limit its auto shipments to the U.S. in the 1980s helped prevent Washington from imposing higher import duties. A similar move from Beijing, especially in sectors of key concern to Washington, like electric vehicles and batteries, would mitigate criticism from the U.S. and others over China's "economic imbalances": heavily subsidized companies making stuff for slim profits but saturating global markets, to the detriment of other countries' manufacturers...

The Xi leadership has indicated a desire to cut a deal with the Trump administration to head off greater trade attacks... Similar to Japan, the Chinese advisers say, Beijing may also consider negotiating export restraints on EVs and batteries in return for investment opportunities in those sectors in the U.S. In some officials' views, they say, that might be an attractive offer to Trump, who at times has indicated an openness to more Chinese investment in the U.S. even though members of his administration firmly oppose it.
The article notes agreements like this are also hard to enforce, "particularly when Chinese companies export to the U.S. from third countries including Mexico and Vietnam."

London's Heathrow Airport resumed operations late Friday after an electrical fire at a nearby substation forced a full-day closure, causing global travel chaos with hundreds of canceled flights and thousands of stranded passengers. The explosion at a Hayes substation 1.5 miles from the airport knocked out power early Thursday, requiring 70 firefighters to battle a blaze in a transformer containing 25,000 liters of cooling oil.

Despite backup generators, Europe's busiest airport couldn't maintain normal operations, forcing flights to divert to airports across Europe and as far as Bangor, Maine. "Contingencies of certain sizes we cannot guard ourselves against 100%," Heathrow CEO Thomas Woldbye told the BBC. "This is as big as it gets for our airport." British Airways, which planned to carry 100,000 passengers Friday, prioritized long-haul flights to Australia, Brazil and South Africa when operations resumed after 4 p.m.

An anonymous reader quotes a report from TechCrunch: Volkswagen's ultra-cheap EV called the ID EVERY1 -- a small four-door hatchback revealed Wednesday -- will be the first to roll out with software and architecture from Rivian, according to a source familiar with the new model. The EV is expected to go into production in 2027 with a starting price of 20,000 euros ($21,500). A second EV called the ID.2all, which will be priced in the 25,000 euro price category, will be available in 2026. Both vehicles are part of the automaker's new category of electric urban front-wheel-drive cars that are being developed under the "Brand Group Core" that makes up the volume brands in the VW Group. And both vehicles are for the European market.

The EVERY1 will be the first to ship with Rivian's vehicle architecture and software as part of a $5.8 billion joint venture struck last year between the German automaker and U.S. EV maker. The ID.2all is based on the E3 1.1 architecture and software developed by VW's software unit Cariad. VW didn't name Rivian in its reveal Wednesday, although there were numerous nods to next-generation software. Kai Grunitz, member of the Volkswagen Brand Board of Management responsible for technical development, noted it would be the first model in the entire VW Group to use a "fundamentally new, particularly powerful software architecture." "This means the future entry-level Volkswagen can be equipped with new functions throughout its entire life cycle," he said. "Even after purchase of a new car, the small Volkswagen can still be individually adapted to customer needs." Volkswagen says the ID EVERY1 concept is a compact electric vehicle with a 70 kW motor, a top speed of 130 km/h, a minimum range of 250 km (150 miles), seating for four, and a 305-liter luggage capacity.

Volkswagen has a press release with additional information.

General Motors is partnering with Nvidia to enhance its self-driving and manufacturing capabilities by leveraging Nvidia's AI chips, software, and simulation tools. "GM says it will apply several of Nvidia's products to its business, such as the Omniverse 3D graphics platform which will run simulations on virtual assembly lines with an eye on reducing downtime and improving efficiency," reports The Verge. "The automaker also plans to equip its next-generation vehicles with Nvidia's 'AI brain' for advanced driver assistance and autonomous driving. And it will employ the chipmaker's AI training software to make its vehicle assembly line robots better at certain tasks, like precision welding and material handling." From the report: GM already uses Nvidia's GPUs to train its AI software for simulation and validation. Today's announcement was about expanding those use cases into improving its manufacturing operations and autonomous vehicles, GM CEO Mary Barra said in a statement. (Dave Richardson, GM's senior VP of Software and Services Engineering will be joining NVIDIA's Norm Marks for a fireside chat at the conference.) "AI not only optimizes manufacturing processes and accelerates virtual testing but also helps us build smarter vehicles while empowering our workforce to focus on craftsmanship," Barra said. "By merging technology with human ingenuity, we unlock new levels of innovation in vehicle manufacturing and beyond."

GM will adopt Nvidia's in-car software products to build next-gen vehicles with autonomous driving capabilities. That includes the company's Drive AGX system-on-a-chip (SoC), similar to Tesla's Full Self-Driving chip or Intel's Mobileye EyeQ. The SoC runs the "safety-certified" DriveOS operating system, built on the Blackwell GPU architecture, which is capable of delivering 1,000 trillion operations per second (TOPS) of high-performance compute, the company says. [...] In a briefing with reporters, Ali Kani, Nvidia's vice president and general manager of automotive, described the chipmaking company's automotive business as still in its "infancy," with the expectation that it will only bring in $5 billion this year. (Nvidia reported over $130 billion in revenue in 2024 for all its divisions.)

Nvidia's chips are in less than 1 percent of the billions of cars on the road today, he added. But the future looks promising. The company is also announcing deals with Tier 1 auto supplier Magna, which helped build Sony's Afeela concept, to use Drive AGX in the company's next-generation advanced driver assist software. "We believe automotive is a trillion dollar opportunity for Nvidia," Kani said.
