It probably depends on how you structure your life in the city. If you start without a car then you build your life and contacts more locally. That’s how people did it in the past before cars. Admittedly there were a lot more local shops and employment opportunities. This is where walkable cities comes in.

It would be difficult to just give up the car as a lot of people have too much distance in their lives and public transport doesn’t go where they need to be in a timely fashion.
