Earlier quoted context omitted.
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).
And there's plenty of space in the US; most roads can be half as wide and still service most cars. Plenty of space to build in a hard shoulder / fencing and a dedicated two-way bike lane. 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.
For the record, I am a cyclist. I would love to use it more. But the roads are too dangerous, and town hall meetings are always full of the same two sides talking past each other. It's a perception issue, but hardcore cyclists refuse to acknowledge it. So the situation continues to not improve.
