I agree that a self-driven car takes away the need to abide by a schedule or get to a station, but I think it's not enough to make domestic flights obsolete. People take short flights because, despite all the inconveniences, it cuts down on the time you're stuck in a vehicle for an extended period of time. That's why people still prefer flying to trains, despite trains being much more comfortable and less of a hassle to board.
Sure, people sleeping in self-driven cars wouldn't have to deal with anyone else, but I don't see sleeping on a self-driven car as ever being as comfortable as sleeping at home or in a hotel. The vehicle is still moving and turning, and you'll still get plenty of noise from other vehicles driving around. So ultimately, I'm sure there'll be plenty of people who will still want to save the time and just fly. People just want travel to be over as quickly as possible.
