I often see urbanists and young people fantasize about life in car free mega cities. Having lived that life for years I can’t imagine why. A lot of cities that are beautiful and attractive also have room for cars. I would even argue it is a big part of what makes those cities attractive. There’s no substitute for the point to point on demand fast transportation that cars offer. In cities that aren’t overbuilt, it makes it so much easier to get things done, see people, and access the outdoors. All that time saved is time to live a richer life.
A good example of a car centric city that is very attractive is Seattle from ten years ago. The city had a strong sense of community because it was composed of intimate neighborhoods mostly with single family zoning rather than mid rise boxy apartment blocks everywhere, ample green space for its population, and roads with little traffic. It is because Seattle was so attractive that people and businesses flocked to it. Now those aspects are going away as density, anti car policies, and other issues are making the overall quality of life worse.
