There is hope. More and more young urbanites in dense cities are already eschewing car ownership for walking and on-demand rentals. Even European-style public transit can only be so convenient[1], and a fleet of selfdriving ubers would be perfect. I hope that this will mean even fewer people decide to own cars and that car ownership becomes increasingly uncommon.

[1] public transit is great for when you have a lot of time and aren't carrying a lot of things. Doing, say, your weekly groceries by bus or walking is annoying af. Source: living in a European city without owning a car.

PS: I live in the US now and not having a car is much more convenient than it was in Europe. Uber and zipcar and getaround are magic. We didn't have that in my city
