Hey! I said it sets a precedent too. Where's my credit dammit!?
There you go.
Plain and simple, not wearing a helmet is (and should be) personal choice. This isn't like speeding a car, you're not hurting anyone but yourself by not wearing one. What's next, you have to wear long sleeves and jeans when riding a bike so you don't scrape up your arms and knees? Our so-called "government" can stay the fuck out of personal decisions.
