Tesla shares fell 6% Friday after the electric vehicle maker’s long-awaited Cybercab update failed to impress investors betting that the company can challenge Alphabet’s Waymo, which currently dominates the U.S. robotaxi market. The two-seat, bronze-colored Cybercab has scissor doors and no steering wheel or pedals, and Tesla said users of its Robotaxi ride-hailing app could take a driverless trip within a geofenced area around Austin. The Thursday event in Austin, Texas, was limited to invited attendees, was not livestreamed and did not feature CEO Elon Musk. The National Highway Traffic Safety Administration (NHTSA), the U.S. road-safety regulator, also opened an audit query into whether Tesla properly self-certified the vehicle for public-road use and compliance with federal safety standards. RBC Capital Markets analysts said key questions about pricing, production cadence and regulatory approvals remained unanswered, while Wells Fargo labeled the launch underwhelming and cited early execution issues, including reported routing errors, missed destinations and excessive waiting or driving times. The decline followed a 5.4% gain on Thursday ahead of the event.
