A car can go pretty much anywhere, public transportation not so much. If you can sleep in a self driving car then logistically much more of the world will be accessible to you. Hit a button, go to sleep, wake up wherever you want. To me this would be much more exciting than cheaper taxies.
Except sleeping in a car (or a bus, train, airplane) is really really uncomfortable. But cars more than the rest, since you are much more restrained due to seat belts.
That’s because cars are not designed to be slept in. Inflatable mattress and a seatbelt/harness designed to be worn lying down and the problem is solved.
Exactly. And perhaps it's even that once autonomous cars have proven themselves enough, you wouldn't even need a seatbelt for a regular ride. The car might just beep once every few hours to ask you to buckle up on particularly dangerous sections, like on an airplane.
