i thought my wife and i would always have our own cars. could never imagine making do with 1. but now i can walk to work so we don't need 2. and if we happen to need to go separate ways, i can uber. make transportation easy, and people will adapt/embrace even if they don't currently like the idea.

Not needing a car is great, but this apply mostly to people living in cities. I would love to walk to work, I would only need to triple my income or downgrade a lot my quality of life by living in a bad small apartment.

Right, definitely not everyone can do it. My point is only that opinions can change if circumstances change.
