Work not fun
I enjoy driving but I hate commuting. That goes for everyone I've talked to about the subject. And I know people who dislike driving under any circumstances. There's many people whose only vehicle is a big pick-up or SUV because they can't afford a 2nd, small car just for commuting. If there was a car sharing service that had a self-driving car at a sufficiently low cost per trip, I think it would eventually become very popular, both because you can use the time in the car productively & because it reduces stress. The cost factor is difficult to determine because the costs of insurance & of maintenance are partly fixed & the cost of debt service is fixed (on that big SUV they keep in the garage)
