I suspect the reason there are now helmet laws is owing to the pressure aimed at law makers. Basically it says that a fair amount of motorcyclists ride with minimal insurance, usually liability. That is costing tax payers millions per year in health care costs because a fair majority of them are not insured and we, the taxpayer are footing the bills for their care after they are parapalegics, or vegetables.
Laz, I used to love riding without a helmet, I had one fall after my girlfriend at the time, convinced me to wear one (a threesome was involved of two females and me) and I can honestly say it saved my life.
Think about it, I am sure your loved ones want yas around (hell I'd even miss you), so think about getting an "approved" one just to be safe because of the idiots out there.
