The NHTSA has opened a formal investigation into Tesla’s deployment of its two-seat Cybercab in Austin, Texas, after the company began offering rides in limited city areas with vehicles that lack a steering wheel, pedals or traditional driver controls. Tesla reports that 45 Cybercabs are now registered in Texas, prompting regulators to examine safety compliance and the adequacy of autonomous-driving safeguards.
