By Abhirup Roy SAN FRANCISCO, Sept 4 (Reuters) - Tesla's race to deploy Cybercab robotaxis will put regulatory limits to the test as the EV maker begins paid rides in the sporty, two-seaters that run without a steering wheel,

Tesla's Cybercab has officially hit Austin streets, but federal regulators wasted no time opening an investigation into how the driverless EV was certified.

Tesla launches its purpose-built Cybercab in Austin, Texas but its one million robotaxi miles look tiny next to Waymo.

Elon Musk’s electric-vehicle company is holding a launch event for the Cybercab autonomous vehicle on Thursday, but details have been sparse.

The company published a form on its website Thursday soliciting info from people who are interested in "Cybercab fleet vehicle purchasing."

Tesla teased a Cybercab event weeks ago, signaling the introduction of its purpose-built robo-taxis with no pedals or steering wheel. The launch took place and Tesla said Cybercab rides open to the public after the closing bell on Friday.
