Feds open investigation into Tesla's driverless Cybercab

The National Highway Traffic Safety Administration opened an investigation Friday morning into Tesla’s decision to launch its Cybercab on public roads without a steering wheel or pedals — just hours after the company put the first Cybercabs onto the streets of Austin, Texas. Federal vehicle safety rules require manual controls like brake pedals, though the Department of Transportation has recently proposed removing those requirements for vehicles designed to be driven autonomously.

“NHTSA fully supports the safe development and deployment of automated vehicles. But as the federal regulator, we need to ensure that all of our laws are followed,” administrator Jonathan Morrison said in a statement, adding that balancing innovation with safety oversight will let the U.S. maintain its global leadership in autonomous-vehicle development. NHTSA said Tesla told the agency it had self-certified the Cybercab as compliant with the Federal Motor Vehicle Safety Standards — the standard process automakers use — and that the agency is opening the investigation to examine the process and technical data behind that certification, including the extent to which it relied on determining that certain federal standards don’t apply to the Cybercab.

There’s precedent for this kind of inquiry. In 2022, Amazon-owned Zoox self-certified its cube-shaped robotaxi, which also lacks a steering wheel and pedals, prompting NHTSA to seek more information and, the following year, formally launch the same kind of audit query it’s now using for Tesla. That investigation slowed Zoox’s path to commercialization even though the company maintained its self-certification was sufficient. In 2025, regulators granted Zoox an exemption to demonstrate — not commercially operate — its technology; the company then filed for a temporary exemption from eight federal safety standards, which it received final approval for in July 2026, capped at adding 2,500 vehicles a year to its commercial fleet over the following two years. Zoox launched commercial service in Las Vegas several weeks later.

Whether Tesla faces a similarly long process is unclear — Zoox’s case spanned both the Biden and Trump administrations. NHTSA has acknowledged it’s working to update the safety standards around manual controls, saying it hopes to finish those changes and remove “unnecessary barriers” to AV innovation in the coming months, but that existing rules remain in force until then.

Why it matters

The outcome could determine how quickly Tesla can scale Cybercab into a commercial robotaxi service — Zoox’s nearly four-year path from self-certification to paid rides suggests Tesla’s timeline may run years, not months.
