I think this highlights the best path forward. Large-but-not-Manhattan cities should eliminate cars in the densest areas of their downtown, where it makes sense. Jersey City did this in their downtown area, and it seems to be going well. As people who want to live without cars move to the downtown zone, the area adapts to meet their needs (in terms of the types of stores etc). If the policy proves popular, the city has the option of spreading the "car-less" zone as the dense urban core grows. Similar to suburban sprawl, but inverted, I suppose.
