A bicycle helmet is not designed to protect your head from the impact of a car. It may try, but your helmet would have to be huge. A bike helmet is made to slide across the pavement in the event of a crash. This allows you to decelerate at a slower pace and minimize damage. Think of a bike helmet more like a ski helmet. It protects you from the ground, and will do very little if you ski into a tower. http://www.bhsi.org/mips.htm http://www.bhsi.org/mips.htm
