You may not have noticed that the younger generation of folks isn't rushing out to get their driver's licenses. Whereas we had to drive to hang out with our friends, they do so on social media. For them, a car is just a capital expense that makes no sense - live in the city, talk to your friends 24/7 using your phone, and take transit everywhere. Restrict phone data or the internet and you might evoke outrage from them, but getting rid of cars will probably get a response of, "I don't own one."
This is certainly true in Oregon. I woked in driver ed there from '07 through '16, starting and operating a driving school from '11-'16, and the percentage of folks reaching 18 without a license is going down and for those who do get licensed as minors more of them are doing it at 17 rather than 16 (unlike me who was at the DMV bright and early on my 16th birthday - and most of my friends did something similar). A good number of our students were learning to drive primarily because their parents wanted them to (to haul siblings around, or just to haul themselves to all of their activities) and not because they wanted it for themselves. In large part the kids would be happy to chill in the car and text, read, nap while someone else drove them around. I don't necessarily think this is just because of social media through - most of the teens I worked with the past ten years were VERY busy and driving was just one more thing they'd have to do, and frankly they were pretty tired
I don't know what's going to happen, but I do know that if someone invents a rapid personal transit system that can let you text or get where you want to go while tipsy, cars and motorcycles will become an endangered species simply through lack of demand. Just like I haven't seen a horse and buggy in downtown in a long time.
I think this is true - particularly for use in urban areas.
As for horse and buggy, when I read that I thought, well gee - I saw those in use in NYC, Philadelphia, St. Louis and a couple of other cities in just the last year - maybe self driving cars are on their way to the same sort of novelty activity....maybe we should be opening closed "driving ranges" - something between a racetrack and a plain old neighborhood...
