While the initial testing will use Tesla's own fleet of cars, regular customers may be able to add their cars to the ride-hailing fleet next year, Musk says.

Tesla will launch an “unsupervised, no one in the car” robotaxi service in Austin, Texas, in June, Elon Musk said in an earnings call Wednesday. “We just want to put a toe in the water, make sure everything’s okay, put a few more toes in the water, with safety of the general public and those in the car as a top priority,” Musk said.

Elon Musk said today that Tesla will launch “unsupervised full self-driving in Austin as a paid service” in June.
