I treat most highways in America like the highways described in Farenheit 451. Thankfully, I live in a rural area which means there are tons of standard roads that are very unpopulated, but even then... "sharing" a road between a 2-ton metal cage and anything else is terrifying for anything but the automobile (2-ton metal cage). The common criticism though, is that biking in the US is much harder logistically. Many people commute for over an hour at 60mph+ to get to work. This would be implausible on a bike.
