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.

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.
