Have you ever actually been to Europe? Public transit is pretty good in first-tier cities like Vienna / Stockholm / London where tourists spend most of their time. But out in the smaller cities and rural areas where regular people live there's very little public transit except for slow and inconvenient buses. So everyone drives. Or if they're too poor to afford a car then they just don't go anywhere.

This is my observation as well, it's also true in the USA. Places like Chicago and NYC have good public transit. You can easily live there without a car, in fact it's easier and certainly cheaper to not have to deal with owning a car. If you visted NYC and formed your impression of public transit in the USA based on that, it would be very wrong. Likewise you cannot assume that because Copenhagen has great public transit and bicycle infrastructure that all of Europe is like that. Get out to the smaller cities and towns and you'll find that many more people own cars and drive everywhere.

are you familiar with population distributions and the fact that more of the word lives in urban areas than rural?

Citation needed, because this is obviously false.

What a horrible thing to say.
