I think you're really whitewashing things. A better description would be that the US is a huge country with a few, select metro areas that are pedestrian/cycle-friendly (and even then, only in certain parts), while the vast majority of the country is very unfriendly to them.
I never claimed the majority of the US was great for bicycling; just that Florida was exceptionally bad. I think maybe you read more into that statement than was actually present. (I think I understand the confusion — I intended to say there was a broad range of infrastructure friendliness.)
