> Most of the world didn't ditch cars, exactly. They just predate them.
It's true they predate them, but then so do most American cities. When the car arrived the American cities opted to expand their cities, giving everyone their own block of lawn to live on. The European cities could have expanded in the same way too. Utrecht went as far as to build freeways to make it possible. But in the end, they opted not to and Utrecht in particular turned their brand new freeways into canals.
> Car culture is recent and pretty uniquely American.
American certainly has it's own unique culture, but I think we are discussing a specific characteristic of that culture which it shares with other countries like Australia, Canada and New Zealand. The density of most cities in those countries is so low owning a car is mandatory. Existing without one is almost impossible. I know because live in one. Quoting a Japanese exchange student who lives with us for a while - to her surprise even with two cars getting to everywhere we had to be in an average week was a major logistical exercise. In the countries @n3storm is talking about, car ownership is completely optional.
