The vast majority of people in China don't own cars and don't live in suburbs, most people live in apartment complexes where everyday services are within 20 minutes walk from their building.

Like American car culture is completely unsustainable in China. China right now has a 1/4 of the per capita car ownership of the US and they have some of the worst congestion in the world. Beijing and many other large cities only allow people to drive their cars two or three days out of the week. They base it off the last number on your license plate, and the cops will stop and potentially impound your car if you are driving on the wrong day. And this policy has like 90% support becuase of how bad traffic is otherwise.
