There's a big difference between cycling and motorcycling, between bicycle helmets and motorcycle helmets. I don't compare the protective qualities of one against the other because it would be ludicrous. I wore a bicycle helmet out of habit because I came from a motorcycling background, but was soon here disabused of the notion that bicycle helmets provided even a fraction of the protection a MC helmet does.

Still, what meager protection a bicycle helmet might afford in the rare case that I crash on a bicycle, and in the rarer case that said crash involves a headstrike, is worth it to me.
