And I can't explain how people live without cars. It boggles me. Sure we have big roads, but seriously, who wants to walk for 20 miles every day?

The point made in the discussion of traditional cities I linked is that living without a car can be a nightmare in places that were designed around cars but that many cities that were not designed around cars are very livable without them. I've lived in Vancouver for 7 years without a car quite happily and it's not even particularly pedestrian friendly compared to many European cities (though it is by North American standards). I only walk about 3-4 miles a day.
