Europe has a lot more people in cars than on transit. in general the cities are somewhat petter but there is a lot of room to do better. not that you are wrong but you need to do better not focus on butting down the us.
Who said anything about America? Take a look at yourself: Sweden, Spain, Italy, France, Germany - each does some really good things that are not repeated in other countries. That list is not exhaustive, but there is a reason each country is on the list, do you know what you have to learn because they are better than you (unless one of them happens to be you). Then look at the larger world - what are your learning from Chile, South Korea, Japan... Again not an exhaustive list, but each country has significant things they are doing better than you. Even in America, New York city, or Seattle, have things to teach you, but no you have to look down on America and so won't learn the good instead, you just want to feel better than us because of the bad things.
