I just stumbled across this article on Wiki about a car free community in Germany. Wiki explains that this community is "almost" car free although there are streets with car access, it's the lack of parking spaces that limits the amount of cars in certain areas of the community.
Vauban is a new neighborhood of 5000 inhabitants and 600 jobs 4 km to the south of the town center in Freiburg, Germany. It was built as "a sustainable model district" on the site of a former French military base, and is named after Sébastien Le Prestre de Vauban, the 17th century French Marshall who built fortifications in Freiburg while the region was under French rule. Construction was begun in the mid-1990s, and by the beginning of 2001, 2000 people had moved in.Interesting stuff. I saw that there are a number of car-free communities besides Vauban. Has anybody ever been to one of these communities?
