That's because the laws are made by people who don't ride motorcycles. When they change that law I did a study for the next two years I don't exactly remember the numbers but the first year was it over 2,000 people died riding motorcycles and only $160 some were without helmets I know personally two people who died with broken necks from the weight of a helmet when you hit an impact the only study they do is the what pressure it takes to crush that helmet they don't look at you've got a 8 to 12 lb instrument on top of an 8 lb head on the weakest part of your body which is your neck ridiculous but they'll get a past again
