In Holland they learned the hard way that you have to physically cordon off half of every road for bicycles.

Americans seem really good at ignoring cyclists being run over. Children don't seem to walk/cycle and rely on being driven around by their parents here so they don't die as much (good, obviously people know its not safe) but doesn't promote infrastructure investment for alternative transit (bad).
But that's only part of the problem, the amount of entitled, and selfish drivers that ignore traffic rules, lights and sometimes even roads is crazy.
