I've been to a few cities in the US (I'm a foreigner), like Denver and Atlanta, and they are very pedestrian hostile. Almost no sidewalks, every street looks like a roadway (large) and every shop seems to belong to these islands where you can park your car and do your stuff. Not saying this is good or bad, but it's very different from every other country that I've came across. An exception in the US would be Las Vegas.
