But it feels like (in SF at least) we have people with conflicting goals: they want to live in a city, but they want their experience to be similar to suburbia.
I want to live in a city and for it to actually feel like an urban environment! I want to walk everywhere for my day-to-day needs, and take transit for everything else. I want to sell my car and rent one only for the times I want to leave the city. But we're in this weird middle state where that often doesn't work. My guess is that the only place in the US where it really does work is NYC, and then maybe even only really in Manhattan.
It's probably the case that it's the only place in the country where it's considered perfectly normal as an adult not to own a car even if you have plenty of money.
There are--especially given Zipcar/Uber/etc.--other cities where people can get buy without owning a car, especially if it's a young post-college lifestyle. But it probably requires organizing your life around not owning a car to a certain degree.
I have been told that central Washington D.C. and Chicago are also very transit and pedestrian friendly. It is not a requirement to own a car in those places.
Stop trying to tell people what they ought to want. Not everyone agrees.
