Apparently at an ABATE rally protesting motorcycle helmet laws, one of the participants had the rear tire of his bike hit a slippery patch of irony, pitching him over the high side and onto the front page, dead of head injuries that would have been prevented by wearing a helmet.
You can't make stuff like this up. Well, you could, but people would accuse you of being formulaic and unrealistic.
Personally, I'm pretty religious about wearing a helmet, and a full-face one at that, when I'm on a motorcycle. Just like I fasten the seatbelt on the car before backing out of the driveway, and feel weird just sitting in the car without being belted in, I won't ride around a parking lot without a motorcycle helmet.
I washed out the front tire one time on a rain-slick interstate at ~60mph, and the resulting get-off netted me a busted thumb, broken rib, and a cracked shoulder blade. The helmet I was wearing, which I still have, looks like somebody hit it a good lick with an angle grinder at the spot that would have been my left cheekbone had there not been polycarbonate in the way. That would have hurt, and it would have changed an accident that got me basically some bumps and bruises and a few days off work into skin graft city.
But I don't think not wearing a helmet should be against the law. People should have the freedom to create and manage their own risks. When the state gets too worried about my health, it makes me nervous. Why do they care if I get hurt or killed, anyway? Down that train of thought, everything starts to get pretty Matrix-y...
(And yes, despite being a seatbelt and motorcycle helmet user, I never wear a bike helmet. Like I said, we should have the freedom to create and manage our own risks...)
