Tesla Cybercab Safety Probe Opens After Driverless Robotaxi Launch in Austin

A Tesla Cybercab safety probe has been opened by US regulators after the electric vehicle company began commercial deployment of its new fully driverless robotaxi in Austin, Texas.

The US National Highway Traffic Safety Administration (NHTSA) announced on 4 September 2026 that it had opened an Audit Query into Tesla’s certification of the Cybercab. The investigation covers the technical data and processes Tesla used to claim that up to 1,000 Cybercabs comply with federal motor vehicle safety standards.

Why NHTSA Is Investigating Tesla Cybercab

The Cybercab differs significantly from conventional vehicles because it does not have permanently attached traditional driving controls.

NHTSA said the vehicle lacks:

• A steering wheel
• Brake pedal
• Accelerator pedal
• Conventional mirrors

Tesla has self-certified that the Cybercab complies with applicable Federal Motor Vehicle Safety Standards.

However, NHTSA is now examining the basis for that certification, including whether Tesla decided that some existing safety requirements did not apply to the autonomous vehicle.

Cybercab Commercial Service Begins in Austin

Tesla began commercial deployment of a limited number of Cybercabs in Austin, Texas, on 3 September 2026.

The two-seat autonomous vehicles are being introduced gradually, with Tesla planning to expand the number of vehicles and locations over time.

Texas registration records showed Tesla had 420 autonomous vehicles registered in the state as of Friday morning, including 45 Cybercabs.

The launch represents a major step in Tesla’s long-term strategy to build a large-scale autonomous ride-hailing business.

Existing US Safety Rules Still Apply

US regulators are already considering changes to vehicle safety rules to better accommodate cars designed entirely for autonomous driving.

NHTSA has proposed updating standards covering areas such as brake pedals, rear-view mirrors, windshield wipers and lighting.

However, the agency stressed that existing regulations remain in force until those changes are completed.

Automakers normally self-certify that vehicles comply with federal standards, but NHTSA can investigate when questions arise over whether the requirements are being met.

Tesla had not previously requested an exemption for the Cybercab, according to NHTSA.

What Happens Next?

The investigation does not mean NHTSA has concluded that Tesla violated federal safety rules.

Instead, regulators will review Tesla’s technical information and certification process to determine whether the Cybercab legally complies with current standards.

Tesla had not publicly responded to Reuters’ request for comment when the investigation was announced.

The outcome could also influence how US regulators approach future autonomous vehicles designed without conventional human controls.
