JRA, Boluvard cruising is basically a N American endeavour... Most other people around the world use the bike as a vehicle to get around, thus the higher number with no helmets and seemingly no death by not wearing helmets problem... doing all the things the N Americans are doing with vehicles... Their whole infrastructure is set up to accommodate such an endeavor, ours isn't, thus, it's much more/can be a more dangerous way to get around in N America, thus helmets can be more effective in N America then in other parts of the world... As I see it...
