The problem is that you'd have such a huge supply of available cars between 8-6pm M-F that you'd never be able to turn a profit if driverless cars became commonplace.

The parking lot at my office complex has more capacity than my city's entire public transit and taxi system combined. Releasing that into the market just means razor thin profits with the risk that someone will trash your car.

I would argue that the market would not be available for low end cars, but owning a nicer car would create a larger incentive for the consumer.
