I don't know much about European cities but maybe it's easier to build housing there than it is here because that's always the main issue in north america.

The only reason people live in the suburbs where everyone is forced to drive is because a) housing it cheaper and b) its safer (most EU cities probably dont have anywhere near the crime levels of the US) c) its easier to raise kids because decent schools dont have waiting lists and basic stuff like grocery stores are cheaper

I know it's a meme on Reddit but people living outside metropolitian areas aren't there simply because they are pro-car.
