Just because a car is traveling at some given speed doesn't mean your head is going to impact anything at that speed. No helmet is claiming to handle a 65mph impact. They are made to handle a drop from two meters at the speed created by gravity. In other words, a fall, which is a hell of a lot more common when getting hit by a car. The anti-helmet crowd will continue to cite that the helmet doesn't save you from injuries over areas the helmet doesn't cover in that situation too. It's a never-ending game for them without any rational and real concern for making better choices in terms of standards of protection and marketplace awareness, etc.
