Tesla is now testing its robotaxi fleet in Austin without human safety monitors inside the vehicles, Elon Musk said. The announcement followed a video posted on X on Sunday that appeared to show a Tesla Model Y driving through Austin’s streets with no occupants. Musk, Tesla’s CEO, quickly confirmed the buzz.

“Testing is underway with no occupants in the car,” he wrote in response to the viral video. However, this appears to be for testing purposes and not yet available for paying customers.
