Tesla introduced a 45‑vehicle driverless Cybercab fleet in Austin, but the rollout triggered an NHTSA safety investigation within hours. The launch drew mixed regulatory responses, including a San Antonio zoning recommendation on a Tesla charging-lot lease and road testing in Jacksonville, while European authorities capped deployments at 1,500 units. Shares fell nearly 6% after the event, reflecting market skepticism about the product's viability.

TSLA unveiled its Cybercab robotaxi service in Austin on Thursday, deploying 45 driverless vehicles authorized for autonomous operation. The launch demonstrated the technology's functionality, but the company had removed the Cybercab from its 2026 volume production schedule in July due to battery‑pack capacity constraints, raising questions about scalability .

Within hours of the rollout, the U.S. National Highway Traffic Safety Administration opened a formal safety probe into the steering‑wheel‑less, pedal‑free vehicle, citing concerns over Tesla's self‑certification process . The regulatory scrutiny intensified as federal investigators sought answers about the vehicle's compliance and safety protocols.

Meanwhile, local regulators showed a mixed stance: San Antonio's zoning commission recommended approval of a Tesla charging-lot lease on Josephine Street, a decision that still needs city council sign-off, while Jacksonville began testing Cybercabs on its roads, prompting scrutiny of the city's NAVI program. In Europe, authorities capped the number of Cybercabs at 1,500 units, highlighting divergent regulatory environments.

The market reacted sharply, with Tesla's stock dropping 5.92% to close at $354.08, marking a decline of over 6% following the closed‑door event that lacked Elon Musk's appearance and live streaming . Analysts cited the regulatory probe and the limited fleet size as factors dampening investor confidence, with Wells Fargo among those calling the demonstration underwhelming.
