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.

Tesla’s fourth-quarter adjusted profits rose slightly amid a big push to sell its electric vehicles with offers of zero financing and other incentives, but the results still fell short of Wall Street forecasts.

It’s hard to fault a CEO who grows a company beyond $1 trillion in value. Elon Musk managed the feat by upending the automotive market with Tesla’s electric vehicles and extended its lead with broader battery power.
