The main thing I think about self-driving is if it truly were self-driving and you could sleep in the car while it drives to a destination overnight. Even if it were only highways. That would be really cool.
Depending on the destination of course, I often find having a car in a city like having an albatross around my neck. The benefits or features get outweighed by traffic and parking. I'll take good public transit and a set of headphones.
