It's certainly city thinking, I agree. However, if the demand for personal vehicle ownership in cities drops but stays level in suburban and rural areas, the overall demand still drops (or, perhaps, doesn't grow in the next decade).

I guess my point was that personal ownership of small cars will be the first to decline as self-driving and service-based (Uber and the like) car use increases.

The SUV/Truck car market I believe will last a little bit longer because a large part of the use of those things is for transportation and storage of personal belongings as well as numerous children, which Uber/Lyft don't cater as easily to.
