I don't think fatalities are necessarily relevant. A helmet probably isn't going to help you if a car runs you over -- but then again, very little will. However, for the vast number of other possibilities, a helmet offers a decent level of protection. I personally find the trade-off worth it, and I don't particularly understand the rationale behind not wearing a helmet. I'd rather be safe with messed up hair than sorry and a concussion. But to each his own.
