Street parking, driveways and home garages are forbidden in the new district near the French and Swiss borders. The streets are completely "car-free", but downtown Freiburg car ownership is allowed but there is only two places to park- large garage, or a home. 70% of Vauban families do not own cars. A mother of two had said "When I had a car I was always tense. I'm much happier this way" as she walks the streets where the swish of bicycles an chatter of children drown the occasional motor.  There's plenty of advantages of limiting car usage.
