Federal regulators are investigating whether Tesla's new Cybercabs meet safety requirements after the company launched its steering-wheel-free robotaxi service in Austin, Texas. The National Highway Traffic Safety Administration (NHTSA) announced it would examine Tesla's self-certification process and technical data to determine if the two-seater vehicles, which lack steering wheels, mirrors, and brake pedals, comply with federal standards.

Why Did NHTSA Launch This Investigation?

Tesla began offering Cybercab rides in Austin on September 3, 2026, with company head Elon Musk launching the service with considerable fanfare. However, the NHTSA raised concerns about whether the vehicles meet existing safety regulations that typically require all vehicles to have manual controls. The agency said it would conduct an audit to examine the certification process Tesla used before deploying the vehicles.

Before the launch, Tesla had relied on a self-certification procedure to ensure compliance with federal safety standards. However, the NHTSA apparently questioned whether this internal review was sufficient, given the unprecedented nature of a completely steering-wheel-free vehicle operating as a commercial robotaxi service.

How Does Tesla's Cybercab Compare to Waymo's Robotaxi Service?

Tesla's new Cybercab service represents a significant departure from its existing robotaxi network, which uses modified Tesla Model Y vehicles with human safety monitors. The company's fleet registered in Texas is less than half the size of Waymo's autonomous vehicle fleet, which operates cars that retain human controls but have no human drivers behind the wheel.

Tesla plans to eventually integrate the steering-wheel-free Cybercabs into its larger robotaxi network as the primary driverless vehicle model. The company has been operating its existing robotaxi service in Austin for more than a year and has expanded to five other Texas and Florida cities. The new Cybercab service initially launched with rides available only in some parts of Austin.

What Are the Key Differences in Waymo and Tesla's Robotaxi Approaches?

• Vehicle Design: Waymo's autonomous vehicles retain steering wheels and brake pedals for emergency situations, while Tesla's new Cybercabs completely eliminate these manual controls.
• Fleet Size: Tesla's Texas-registered fleet is less than half the size of Waymo's autonomous vehicle fleet, indicating a significant gap in deployment scale.
• Safety Monitoring: Tesla's existing Model Y robotaxis include human safety monitors, whereas Waymo's vehicles operate without human drivers but retain mechanical controls.
• Regulatory Approach: Tesla relied on self-certification to deploy Cybercabs, while Waymo's approach with retained controls has apparently faced fewer regulatory questions.

What Challenges Is Tesla Facing Beyond the NHTSA Investigation?

The Cybercab investigation is not Tesla's only regulatory concern. The company is currently facing several federal probes into the safety of its self-driving software. These investigations examine different aspects of Tesla's autonomous driving technology and its real-world performance.

One probe is examining the software's role in several Tesla crashes that occurred in fog, sun glare, and other low-visibility conditions, including an incident in which a pedestrian was killed. Another investigation is looking into dozens of incidents where Teslas using partial self-driving software ran red lights or drove on the wrong side of the road, sometimes resulting in crashes and injuries. A third investigation is examining why Tesla apparently violated regulatory requirements by failing to report crashes promptly.

"It's open to the entire public," said Ashok Elluswamy, Tesla AI Chief, regarding who could ride the Cybercabs.

The timing of the NHTSA investigation has already affected Tesla's stock price. Tesla stock declined 5.92% to $354.08 by the close of trading on Friday following news of the probe, reversing many of the gains the stock had achieved the previous day.

What Are Tesla's Plans for Cybercab Pricing and Expansion?

Tesla has not yet specified when it will begin charging fares for Cybercab rides. However, executives at the launch event described plans to use dynamic pricing, which would increase prices during periods of high demand, while promising what they called "a first-class experience at coach price".

Musk has announced plans for a national rollout of the Cybercab service, describing it as part of a cheap, driverless taxi service that he promises will transform how people travel. The company updated its robotaxi website to indicate that Cybercab rides were initially available only in some parts of Austin, suggesting a gradual expansion strategy.

Several Tesla investors and social media personalities in Austin shared enthusiastic reactions to the Cybercab, posting videos of their rides and the launch event. However, the NHTSA investigation suggests that regulatory approval may not be as straightforward as Tesla anticipated, potentially affecting the timeline for broader deployment of the steering-wheel-free vehicles.
