I have no actual idea, but I wear a helmet because I feel that the cost of wearing a helmet is less than treatment would be if I crashed, hit my head, and wasn't wearing a helmet in a less than "serious head injury" situation, which would be the majority of head injuries sustained in a cycling accident.

You talk about the limitations of helmets, but these "limitations" are in excess of what protection a naked head might provide in the case of a crash resulting in head injury. Like other helmet-skeptics, the language you choose is telling and prejudiced...
