Tesla shares fell 5.06% on Friday after the company's Cybercab launch event appeared to fall flat. The setback came the same week federal regulators opened an audit into whether the driverless vehicle was properly certified under U.S. safety standards.
Tesla shares fell 5.06% on Friday, a day after the company held a launch event for the Cybercab that appears to have fallen flat. The vehicle's rollout will not be as broad as some investors had hoped.
The Cybercab is a two-seat, purpose-built autonomous vehicle with no steering wheel or pedals. It is expected to be cheaper to operate than other Tesla vehicles and to showcase the company's technological progress.

The launch coincided with new federal scrutiny. On September 3, 2026, Tesla launched paid robotaxi rides in Austin, Texas. That same day, the National Highway Traffic Safety Administration opened an audit, tagged AQ25002, into whether the Cybercab was legitimately self-certified under Federal Motor Vehicle Safety Standards. Tesla chose to self-certify the vehicle rather than seek a regulatory exemption, a pathway that caps manufacturers at 2,500 vehicles per year.
As of September 4, 2026, roughly 1,000 Cybercabs were included in the audit's scope. Of those, 45 units were registered in Texas. That is part of a broader fleet of 420 Tesla autonomous vehicles operating in the state.
The audit does not automatically halt Tesla's operations — an open audit query is an investigative step, not an enforcement action. But if regulators find Tesla improperly classified certain safety standards as inapplicable, the company could face a recall or be forced to seek a formal exemption capping annual production at 2,500 units.
