a self driving car

Self driving cars are evidently, and not surprisingly, the hot item at current car shows. I think it would be fun to try a self driving car but I would like to experience it in virtual reality first (much more relaxing). I'm wondering though, how much can a self driving car do? Can it take me through the car wash or the drive through window at McDonald's or the drive up window at the bank? Can it pump its own gas? And what about cost? I have a feeling that I could pay for a whole lot of taxi and bus rides for the cost of a new SDC. Although, if it could come and pick me up at the door so I don't need to remember where I parked at the mall or grocery store it might just be worth the price. Something to think about.
