I suspect this is data from insurance actuary data based on reported accidents, 19.4 zone might occur where you have a biker that plows into the car that is making the left hand turn into the bikers path which is common in the area where I live.Again, none of those numbers mean a damn thing. Impact from what? I would say most impacts on motorcycle helmets is from them falling off the bike and would most likely land top down, but those numbers suggest that is the least likely place of impact. The 19.4% is totally out of line with the rest of the numbers on the helmet. It's all BS.
x's 2 on "Bastards" I'm still laughing at his comment of why he doesn't ride with a helmet.I met a guy who didn't wear a helmet when he rode because "without a helmet, I ride a lot safer". A special kind of stupid, that one. The last time I heard about him he had just run into a riding buddy. Run into as in they made contact in a turn and both went down. The rumor they had just taken the time to smoke a bowl a few minutes earlier had NOTHING to do with it I'm sure. What sucks is they totaled a Ducati F1 in the incident. Bastards.
