Switzerland does have roads choked full of cars. It also has pretty mediocre bike infrastructure.

But this is kind of besides the point - even in the Netherlands I also would use a car if I were taking camping and skiing gear with the kids, and that's fine. But I can also take them in the bakfiets to the grocery store when I want, and that's also fine. Cars have their purpose, but you shouldn't _have_ to use one for basic trips.
