"Car free" is a straw man that's easy to argue against, and misses the point. Rather, most urbanists call for cities that are fair to all who inhabit it, regardless of whether they are currently inside of a car. A bus that carries 50 ought to have priority over several cars that carry 1 apiece. Neighbourhoods should not be artificially embalmed in time by excessive zoning rules to only allow car-dependent architecture. People who live in a city should have an actual choice in terms of what density and transportation mode is best for them. (That definitely includes single family homes and cars). That'll obviously be different from person to person, and even more obviously that'll change over one's lifetime. So make a city liveable and navigable and interesting for those who are 8, 80 and everything in between. Make that the goal, and you'll be heading in the right direction.
