It doesn't though. We accept unsafe intersection in America that could be made a lot safer. I've also lived in 6 different car dependent places in my life, and all of them are amenable to biking, its just a scary proposition with the current infrastructure.

I think a lot of the deaths are put in the realm of "personal responsibility" - we don't pursue safer options, even for cars, because it's always someone's fault something bad happened, rather than intrinsic to the design of the road.

We create roads where people would feel safe going 65mph down them, then slap a 35-45mph speed limit on it, and call it a day.
