This is such obvious BS. Putting aside that Tesla are always making claims about self driving that they can't deliver on, let's just consider the basic logistics of doing this for any customer who lives more than about 300km from a Tesla factory (of which there are two IIRC, and one of those is in Austin and the other is in Fremont)...
How the fuck is the car going to recharge?
It's not like it's going to plug itself in, and there are no staff at Tesla supercharger stations as far as I'm aware. With the range on a typical Model S even getting to LA might be tough if it gets stuck in traffic. Fremont to LA is just under 600km if you're lucky.
