For one data point: I lived in London without a car for several years, and enjoyed it. A lot of people do. One big thing you give up in car-dependent areas is interesting walks. Everything is super-sized to accommodate vehicles, and at a human scale, it's boring. In an older city designed for people, every 10 feet there's something new to catch your eye.

There are tradeoffs, but I much preferred being able to take the train or bus and relax and zone out rather than have spend the entire trip in the vigilant state you need while driving. And while cycling, yes, you have to be vigilant, but you're getting exercise too.

I'm at a point in my life where, I probably don't want to live in the big city as much. (Funnily enough, when I was much younger I never thought I would want to.) But anyway, I'd still much prefer to live in a denser, more walkable suburb, which tend to be unfortunately hard to find and expensive in the US for reasons that are probably already all discussed in comments in this thread.
