Call me a pessimist but I just don't see this being embraced. Maybe someday... but not in 20 years.
Cars are not JUST a mode of transportation for many. They are also a passion and to some, a status symbol. People LOVE having their own car. A place for their sunglasses and other things that "live" in the car. No germs. You have control over your destiny - literally. I just don't see cars leaving our garages and driveways.
I certainly think the technology of cars is changing (more so here than the USA), but I still think personal car ownership isn't going away. 100 years ago, people replaced owning a horse with owning a car. But they still owned something.
