Educate, don't Legislate is my stance on "safety" devices.
As far as the argument about paying for bikers with head injuries, that is lame. In my state alone, I am paying for thousands of peoples healthcare, some illegal aliens. I would not mind adding a couple of bikers to that list and in most cases, they have their own coverage ,which I know increase everyones premiums. But at least they most likely had a job and paid taxes.
Dale Earnhardt was wearing a helmet. Hard hits to the head cause damage to the brain as it goes from 60 to zero inside your skull.
A helmet will help in the scraping type external contact scenarios. As posted earlier, helmets change the injury, but the fatality rate does not.
One more thing:
If a woman can decide to terminate a human life, How come I cannot decide whether or not I want to wear a helmet? Taxpayers pay for abortions as well.
