Man, cars are soooo 20th century! This site shows us how it's done around the world. I can only hope more U.S. metropolitan areas consider car-free layouts. Imagine less pollution, less congestion, less dependence on foreign oil... the benefits are astounding.
PS- Shortly after this post went up, the hate comments started, which is disappointing but not surprising, I guess. Just to clarify for some of you, car-free cities DO exist and are great fun to explore. However, every day I rack up the miles in LA because of a sprawling urban grid and mediocre public transit system. It bums me out, and I welcome the day we can all rely less on cars and do a little more walking under cleaner skies. Call me a hippie if you want, I kinda like it. :)
