I find the city to be better for small children and for disabled people than car focused suburbs to be honest. It means stuff is closer to get to and both groups of people are not completely reliant on other people driving them around to get to places. I do not believe the only way a world can be livable for disabled people, small children, and elderly people, is to pave the entire country in tens of millions of miles of roads and drive on them with heavy and dangerous polluting machines.
