Are about being serious? Its not 'Anti-American' to point out basic facts that literally everybody knows.
Let's just look at some basic comparison between Iowa City and my own city of the same population (mine is somewhat larger in metro city):
about 1.05 million trips
about 50.1 million trips
Its not even close. Why would you look at some tiny US city that doesn't even have actually good results if you compare it to anybody even halfway competent. Why not look for evidence in systems that are better by LITERALLY EVERY METRIC?
That's the basic issue with looking to the US cities for evidence. Their baseline is so pathetic that 'improvements' isn't really that significant.
So maybe its time to start giving a fuck, and not cherry-picking examples to confirm your bias. Actually learn from the systems that achieve the best results.
If I want to look at succesful systems, IDGAF where they are, but how they operate.
