Tesla workers are already hailing robotaxis as part of a test program, Musk says. But a full-blown service requires regulatory approval and could face challenges.

“For Tesla employees in the Bay Area, we already are offering a ride-hailing capability,” Musk said on the company’s third-quarter earnings call on Wednesday. “With the development app, you can request a ride, and it’ll take you anywhere in the Bay Area,” he said, noting that these employee test rides include safety drivers.

Tesla CEO Elon Musk on Wednesday said the electric vehicle maker will roll out driverless ride-hailing services to the public in California and Texas next year, a claim likely to face significant regulatory and technical challenges.
