They're aiming to make it a taxi service. You wouldn't have to own one or deal with maintenance, you'd just pay the $X for your trip. And if it's fully autonomous (which it appears to be), then you -- as a passenger -- wouldn't have to be licensed any more than if you were flying commercial. I have no idea what sort of regulatory hurdles would exist or how easily they'd be overcome. But the fact that they've already built the plane would indicate that they've already taken that into consideration.
