Also more of Europe is plain old walkable or bikeable. When I lived in Oslo I didn't even own a car. In the states there are very few spots you can get by without a car. Even if I wanted to bike from my house to some places there flat out are not sidewalks in a lot of places. Walking is looked down at. There are plenty of blog entries of guys that go without a car even though they could afford it and find dating near impossible not because they live in a city, but because it is such a powerful signal here.
