Just wandering through some web sites tonight and found, dsicovered an interesting site called
autofrei wohnen (carfree living)
Although nearly half of all households in Berlin live without an own car (sic)there still does not exist a carfree quarter for them ! But in this city of ~3,600,000 inhabitants are some
So sounds like even when you have half the households without cars, there are still problems.
Still, sounds like Berlin has evolved well beyond the typical North American city. We talk a lot about Amersterdam here, but there are other cities.
