Plush buses are still buses - you will need to rent a car or take a ride at the end to get where you are going. A self-driving car that takes you from door to door? Yeah, that's completely different.

You live in Pittsburgh. You want to go to NYC for a show. You hop in the car, it takes you to the theater, you get out, it drives itself to a parking lot in NJ to wait. You call for it half an hour before you need it, it picks you up, and it drives you home. That's currently the province of the very rich or the very extravagant. A car that drives itself can do that every night.
