A German community is not just encouraging bicycles, it's avoiding cars. Peddlers in this part of Freiburg don't go door-to-door, they're the residents coming out of the doors. Then they peddle away.
In the development at Vauban, 70% of the resident families do NOT own a car. You might find that in parts of Mahattan or London, but in a suburb? Americans shouldbe reminded that Germany has a mass transit that works. And Vauban has some parking on gthe periphery. You can buy your own parking slot for only $40,000. Cheap by New York City standards.
Here's a site that describes the design and lay-out of Quartier Vauban in Freiburg. Buildings in the area are designed for low energy use and transit centers on a modern tramway (streetcar) system. The area was developed less thantwenty years ago so it had few legacy problems with land use and lay-out.
Despite a growing trend away from cars in some areas, they're not about to disappear. Currently there are about as many cars and trucks as people in the U.S.
