This article is assuming most people will own cars. I think its highly likely that when we get to this level of autonomous driving that its most likely that someone like Ford or Telsa will operate fleets with enough coverage that most people will opt for pay when you want one. So when you are done with the use of the car, it just goes back into the fleet, and onwards to the next passenger. Imagine not actually having to choose a car type but being able to use a commuter 99% and an SUV for the 1 ski trip a year, and a minivan for a night out on the town with lots of friends. This is going to drive people towards a fleet approach - its just plain a better fit for their needs.
