The U.S. government's highway safety agency says Tesla is telling drivers in public statements that its vehicles can drive themselves, conflicting with owners manuals and briefings with the agency saying the electric vehicles need human supervision.

The National Highway Traffic Safety Administration is asking the company to “revisit its communications” to make sure messages are consistent with user instructions.

The request came in a May email to the company from Gregory Magno, a division chief with the agency's Office of Defects Investigation. It was attached to a letter seeking information on a probe into crashes involving Tesla's “Full Self-Driving” system in low-visibility conditions. The letter was posted Friday on the agency's website.

The agency began the investigation in October after getting reports of four crashes involving “Full Self-Driving" when Teslas encountered sun glare, fog and airborne dust. An Arizona pedestrian was killed in one of the crashes.

Critics, including Transportation Secretary Pete Buttigieg, have long accused Tesla of using deceptive names for its partially automated driving systems, including “Full Self-Driving” and “Autopilot,” both of which have been viewed by owners as fully autonomous.

The letter and email raise further questions about whether Full Self-Driving will be ready for use without human drivers on public roads, as Tesla CEO Elon Musk has predicted. Much of Tesla's stock valuation hinges on the company deploying a fleet of autonomous robotaxis.

Musk, who has promised autonomous vehicles before, said the company plans to have autonomous Models Y and 3 running without human drivers next year. Robotaxis without steering wheels would be available in 2026 starting in California and Texas, he said.

A message was sent Friday seeking comment from Tesla.

In the email, Magno writes that Tesla briefed the agency in April on an offer of a free trial of “Full Self-Driving” and emphasized that the owner's manual, user interface and a YouTube video tell humans that they have to remain vigilant and in full control of their vehicles.

But Magno cited seven posts or reposts by Tesla's account on X, the social media platform owned by Musk, that Magno said indicated that Full Self-Driving is capable of driving itself.

“Tesla's X account has reposted or endorsed postings that exhibit disengaged driver behavior,” Magno wrote. “We believe that Tesla's postings conflict with its stated messaging that the driver is to maintain continued control over the dynamic driving task."

The postings may encourage drivers to see Full Self-Driving, which now has the word “supervised” next to it in Tesla materials, to view the system as a “chauffeur or robotaxi rather than a partial automation/driver assist system that requires persistent attention and intermittent intervention by the driver,” Magno wrote.

On April 11, for instance, Tesla reposted a story about a man who used Full Self-Driving to travel 13 miles (21 kilometers) from his home to an emergency room during a heart attack just after the free trial began on April 1. A version of Full Self-Driving helped the owner "get to the hospital when he needed immediate medical attention,” the post said.

In addition, Tesla says on its website that use of Full Self-Driving and Autopilot without human supervision depends on “achieving reliability" and regulatory approval, Magno wrote. But the statement is accompanied by a video of a man driving on local roads with his hands on his knees, with a statement that, “The person in the driver's seat is only there for legal reasons. He is not doing anything. The car is driving itself,” the email said.

In the letter seeking information on driving in low-visibility conditions, Magno wrote that the investigation will focus on the system's ability to perform in low-visibility conditions caused by “relatively common traffic occurrences.”

Drivers, he wrote, may not be told by the car that they should decide where Full Self-Driving can safely operate or fully understand the capabilities of the system.

“This investigation will consider the adequacy of feedback or information the system provides to drivers to enable them to make a decision in real time when the capability of the system has been exceeded,” Magno wrote.

The letter asks Tesla to describe all visual or audio warnings that drivers get that the system “is unable to detect and respond to any reduced visibility condition.”

The agency gave Tesla until Dec. 18 to respond to the letter, but the company can ask for an extension.

That means the investigation is unlikely to be finished by the time President-elect Donald Trump takes office in January, and Trump has said he would put Musk in charge of a government efficiency commission to audit agencies and eliminate fraud. Musk spent at least $119 million in a campaign to get Trump elected, and Trump has spoken against government regulations.

Auto safety advocates fear that if Musk gains some control over NHTSA, the Full Self-Driving and other investigations into Tesla could be derailed.

Musk even floated the idea of him helping to develop national safety standards for self-driving vehicles.

“Of course the fox wants to build the henhouse,” said Michael Brooks, executive director of the Center for Auto Safety, a nonprofit watchdog group.

He added that he can't think of anyone who would agree that a business mogul should have direct involvement in regulations that affect the mogul’s companies.

“That’s a huge problem for democracy, really,” Brooks said.

US to probe Texas-based Tesla's self-driving system after pedestrian killed in low visibility conditions

eyes on the road

The U.S. government's road safety agency is investigating Tesla's “Full Self-Driving” system after getting reports of crashes in low-visibility conditions, including one that killed a pedestrian.

The National Highway Traffic Safety Administration said in documents that it opened the probe last week after the company reported four crashes when Teslas encountered sun glare, fog and airborne dust.

In addition to the pedestrian's death, another crash involved an injury, the agency said.

Investigators will look into the ability of “Full Self-Driving” to “detect and respond appropriately to reduced roadway visibility conditions, and if so, the contributing circumstances for these crashes.”

The investigation covers roughly 2.4 million Teslas from the 2016 through 2024 model years.

A message was left Friday seeking comment from Tesla, which has repeatedly said the system cannot drive itself and human drivers must be ready to intervene at all times.

Last week Tesla held an event at a Hollywood studio to unveil a fully autonomous robotaxi without a steering wheel or pedals. Musk, who has promised autonomous vehicles before, said the company plans to have autonomous Models Y and 3 running without human drivers next year. Robotaxis without steering wheels would be available in 2026 starting in California and Texas, he said.

The investigation's impact on Tesla's self-driving ambitions isn't clear. NHTSA would have to approve any robotaxi without pedals or a steering wheel, and it's unlikely that would happen while the investigation is in progress. But if the company tries to deploy autonomous vehicles in its existing models, that likely would fall to state regulations. There are no federal regulations specifically focused on autonomous vehicles, although they must meet broader safety rules.

NHTSA also said it would look into whether any other similar crashes involving “Full Self-Driving” have happened in low visibility conditions, and it will seek information from the company on whether any updates affected the system’s performance in those conditions.

“In particular, this review will assess the timing, purpose and capabilities of any such updates, as well as Tesla’s assessment of their safety impact,” the documents said.

Tesla reported the four crashes to NHTSA under an order from the agency covering all automakers. An agency database says the pedestrian was killed in Rimrock, Arizona, in November of 2023 after being hit by a 2021 Tesla Model Y. Rimrock is about 100 miles (161 kilometers) north of Phoenix.

The Arizona Department of Public Safety said in a statement that the crash happened just after 5 p.m. Nov. 27 on Interstate 17. Two vehicles collided on the freeway, blocking the left lane. A Toyota 4Runner stopped, and two people got out to help with traffic control. A red Tesla Model Y then hit the 4Runner and one of the people who exited from it. A 71-year-old woman from Mesa, Arizona, was pronounced dead at the scene.

The collision happened because the sun was in the Tesla driver's eyes, so the Tesla driver was not charged, said Raul Garcia, public information officer for the department. Sun glare also was a contributing factor in the first collision, he added.

Tesla has twice recalled “Full Self-Driving” under pressure from NHTSA, which in July sought information from law enforcement and the company after a Tesla using the system struck and killed a motorcyclist near Seattle.

The recalls were issued because the system was programmed to run stop signs at slow speeds and because the system disobeyed other traffic laws. Both problems were to be fixed with online software updates.

Critics have said that Tesla’s system, which uses only cameras to spot hazards, doesn’t have proper sensors to be fully self driving. Nearly all other companies working on autonomous vehicles use radar and laser sensors in addition to cameras to see better in the dark or poor visibility conditions.

Musk has said that humans drive with only eyesight, so cars should be able to drive with just cameras. He has called lidar (light detection and ranging), which uses lasers to detect objects, a “fool's errand.”

The “Full Self-Driving” recalls arrived after a three-year investigation into Tesla's less-sophisticated Autopilot system crashing into emergency and other vehicles parked on highways, many with warning lights flashing.

That investigation was closed last April after the agency pressured Tesla into recalling its vehicles to bolster a weak system that made sure drivers are paying attention. A few weeks after the recall, NHTSA began investigating whether the recall was working.

NHTSA began its Autopilot crash investigation in 2021, after receiving 11 reports that Teslas that were using Autopilot struck parked emergency vehicles. In documents explaining why the investigation was ended, NHTSA said it ultimately found 467 crashes involving Autopilot resulting in 54 injuries and 14 deaths. Autopilot is a fancy version of cruise control, while “Full Self-Driving” has been billed by Musk as capable of driving without human intervention.

The investigation that was opened Thursday enters new territory for NHTSA, which previously had viewed Tesla's systems as assisting drivers rather than driving themselves. With the new probe, the agency is focusing on the capabilities of “Full Self-Driving" rather than simply making sure drivers are paying attention.

Michael Brooks, executive director of the nonprofit Center for Auto Safety, said the previous investigation of Autopilot didn't look at why the Teslas weren't seeing and stopping for emergency vehicles.

“Before they were kind of putting the onus on the driver rather than the car,” he said. “Here they're saying these systems are not capable of appropriately detecting safety hazards whether the drivers are paying attention or not.”

CenterPoint gets go-ahead for $2.9B upgrade of Houston grid

grid resiliency

Texas utility regulators have given the green light for Houston-based CenterPoint Energy to spend $2.9 billion on strengthening its Houston-area electric grid to better withstand extreme weather.

The cost of the plan is nearly $3 billion below what CenterPoint initially proposed to the Public Utility Commission of Texas.

In early 2025, CenterPoint unveiled a $5.75 billion plan to upgrade its Houston-area power system from 2026 through 2028. But the price tag dropped to $2.9 billion as part of a legal settlement between CenterPoint and cities in the utility’s service area.

Sometime after the first quarter of next year, CenterPoint customers in the Houston area will pay an extra $1 a month for the next three years to cover costs of the resiliency plan. CenterPoint serves 2.9 million customers in a 12-county territory anchored by Houston.

CenterPoint says the plan is part of its “commitment to building the most resilient coastal grid in the country.”

A key to improving CenterPoint’s local grid will be stepping up management of high-risk vegetation (namely trees), which ranks as the leading cause of power outages in the Houston area. CenterPoint says it will “go above and beyond standard vegetation management by implementing an industry-leading three-year trim cycle,” clearing vegetation from thousands of miles of power lines.

The utility company says its plan aims to prevent Houston-area power outages in case of hurricanes, floods, extreme temperatures, tornadoes, wildfires, winter storms, and other extreme weather events.

CenterPoint says the plan will:

  • Improve systemwide resilience by 30 percent
  • Expand the grid’s power-generating capacity. The company expects power demand in the Houston area to grow 2 percent per year for the foreseeable future.
  • Save about $50 million per year on storm cleanup costs
  • Avoid outages for more than 500,000 customers in the event of a disaster like last year’s Hurricane Beryl
  • Provide 130,000 stronger, more storm-resilient utility poles
  • Put more than 50 percent of the power system underground
  • Rebuild or upgrade more than 2,200 transmission towers
  • Modernize 34,500 spans of underground cables

In the Energy Capital of the World, residents “expect and deserve an electric system that is safe, reliable, cost-effective, and resilient when they need it most. We’re determined to deliver just that,” Jason Wells, president and CEO of CenterPoint, said in January.

Solidec partners with Australian company for clean hydrogen peroxide pilot​

rare earth pilot

Solidec has partnered with Australia-based Lynas Rare Earth, an environmentally responsible producer of rare earth oxides and materials, to reduce emissions from hydrogen peroxide production.

The partnership marks a milestone for the Houston-based clean chemical manufacturing startup, as it would allow the company to accelerate the commercialization of its hydrogen peroxide generation technology, according to a news release.

"This collaboration is a major milestone for Solidec and a catalyst for sustainability in rare earths," Yang Xia, co-founder and CTO of Solidec, said in the release. "Solidec's technology can reduce the carbon footprint of hydrogen peroxide production by up to 90%. By combining our generators with the scale of a global leader in rare earths, we can contribute to a more secure, sustainable supply of critical minerals."

Through the partnership, Solidec will launch a pilot program of its autonomous, on-site generators at Lynas's facility in Australia. Solidec's generators extract molecules from water and air and convert them into carbon emission-free chemicals and fuels, like hydrogen peroxide. The generators also eliminate the need for transport, storage and permitting, making for a simpler, more efficient process for producing hydrogen peroxide than the traditional anthraquinone process.

"Hydrogen peroxide is essential to rare earth production, yet centralized manufacturing adds cost and complexity," Ryan DuChanois, co-founder and CEO of Solidec, added in the release. "By generating peroxide directly on-site, we're reinventing the chemical supply chain for efficiency, resilience, and sustainability."

The companies report that the pilot is expected to generate 10 tons of hydrogen peroxide per year.

If successful, the pilot would serve as a model for large-scale deployments of Solidec's generators across Lynas' operations—and would have major implications for the high-performance magnet, electric vehicles, wind turbine, and advanced electronics industries, which rely on rare earth elements.

"This partnership with Solidec is another milestone on the path to achieving our Towards 2030 vision," Luke Darbyshire, general manager of R&I at Lynas, added. "Working with Solidec allows us to establish transformative chemical supply pathways that align with our innovation efforts, while contributing to our broader vision for secure, sustainable rare earth supply chains."
