In my younger, poorer years, I had only a motorcycle (and before that a 10-speed bicycle ... if that dates me) to get to work and community college in the middle of a Kansas winter.
I rode very, very slowly. And spilled once or twice (at low speeds). The highways were of course out of the question (but I avoided the freeway regardless of the weather).
But, yeah, I might have been about the only person out there on a bike/motorcycle in the worst of the blizzard.
Most of these things help me avoid killing myself on my bike, but they also reduce my risk of getting killed by others. The idea that there is a bimodal distribution of riders is pretty apparent to me. EDIT: There are likely many "car at fault" crashes where the motorcyclist, though legally in the right, could have avoided the crash.
That said, hell yeah motorcycles are dangerous even for this safety obsessed nerd. Further, I agree they are not a solution for everyone. My bike stays parked if I think I could encounter freezing road conditions. I love riding, but my bicycle is far more practical as transportation than my motorcycle is.
