The trucks and vans can be self driving too.
He didn't say they wouldn't be self driving, he said the people in them would want to own them.
If self driving cars become a thing, I'll still own a car. I don't live downtown, parking is not a problem, and there isn't ever going to be a zip car depot within 5 minutes of me.
So I'll own my car. I'll probably drive it some because i like driving, but sure if I go downtown, I might have it drop me off someplace convenience and then send it off to find a place to park on its own, and have it pick me up later.
Lots of people will still own cars. The only people who shifting away from car ownership are people downtown who don't strictly need one, can get along without one, and for whom owning one would be a huge expense especially because down town you pay for the car, the insurance, and then you have to park it somewhere too... and the parking alone can be less than a rental if you don't drive much.
So its not self driving that's pushing people away from ownership... its "exorbitant parking costs.
People in the suburbs though? People who a rural? People who use a car FOR work or as a daily commuter ... they'll continue to own, whether the car can drive itself or not.
