Uber has rolled out its self-driving car fleet in its hometown of San Francisco, despite lacking the proper permit that state regulators say is required.

Starting Wednesday, riders who request an UberX, one of the company’s budget ride options, may be matched with a self-driving Uber. It is unclear how many of these cars Uber has in San Francisco.

There will be people in the car for now, but I’ll be honest, I’m not sure what I’d do if one of these pulled up to give me a ride when the people are gone.
