When laying on your back, and sliding at 40+ mph (which happens a bit more often than actually hitting a car), if your helmet touches the road, a thing called friction will grab that helmet and twist. Happy broken-neck day. I'd rather lose some skin and/or hair off the back of my head, thanks. An WWI leather pilot-cap would be better than a fiberglass helm.
If you IMPACT anything going fast enough that a helmet would make a difference, you`re most likely going to die anyway. Or at least end up paralyzed from the neck down.
