Carfree.com: Car-Free Cities

carfree.com is an excellent introduction to an urban design concept for a city of 1 million people where there are no cars and every possible destination can be reached in 35 minutes or fewer via walking and public transportation (bicycles optional). Numerous objections can be raised to the ideas presented on the site, but the authors deserve credit for presenting their ideas well. The introduction page is even available in seven languages.
