The National Highway Traffic Safety Administration has launched an investigation into Tesla's driverless taxis, known as Cybercabs, to determine if they comply with federal safety standards. The probe comes after Elon Musk introduced the service in Austin, Texas, on Thursday, and Tesla stock fell by over 5% following news of the inquiry. The agency is concerned that the Cybercabs, which lack steering wheels and manual controls, may not meet required safety standards. This investigation is part of a larger series of probes into the safety of Tesla's self-driving software, including one examining its role in several crashes and another investigating incidents where Teslas using partial self-driving software ran red lights or drove erratically.

Story summary
Federal regulators have launched an investigation into whether Tesla's new driverless taxis, known as Cybercabs, comply with federal safety standards. The National Highway Traffic Safety Administration is questioning whether Tesla fully followed rules when deploying its Cybercabs in Austin, Texas, which lack typical vehicle features like steering wheels and brake pedals. The investigation comes just one day after Elon Musk launched the service on Thursday with a launch event for invitees. Tesla's stock fell by more than 5% to $357.38 on Friday as a result of the news, reversing some of its gains from the previous day. The regulators will conduct an audit to examine Tesla's certification process and technical data, but it is unclear if the Cybercabs meet required standards.
