You can ask your car to stop to go to the bathroom.
Self-driving cars will probably have better reclining that the current ones. It will be a feature.
Even if you don't sleep, going to an airport with sufficient buffer, checking baggage and checking in, security lines, waiting to board, boarding, actual flight, taxi time, getting baggage, getting ground transport is about 4-6 hours even for a 1 hour commuter flight.
And when highway self-driving really improves with mesh networking cars might be able to cruise at 100mph.
Are cars gonna have bathrooms in them now? Because if not, you're now talking about rest areas, many of which are closed at night. And if I wake up having to pee, and the nearest rest stop isn't for an hour, what then? I can't go back to sleep. The nice thing about a plane/train/coach is that the bathroom is right there -- no need to interrupt your travel.
It's all kind of academic anyway because I don't own a car, nor does owning one here make sense anyway as I'd never use it except on road trips, so the plane/train/coach is the only option.
