I think the concern is more about availability. How long does it take for a car to show up each time OP needs to go to the store?
This is a problem with Uber now. I need to be at the airport at 5:00 AM tomorrow morning and I'm just hoping like hell that there will be an Uber around. Most drivers will be home sleeping.
Low-volume times like my example above are where autonomous vehicles can shine. Making the economics work during times of high volume is more difficult. You can always buy more cars, but that's just that many more cars you need storage space for outside of peak hours.
