Well, helmets work by compressing the foam inside. So it actually looks like that one didn't do anything, besides cracking the hardshell that is (don't worry, that takes neglible amounts of energy compared to the total).


As said before, helmets make me feel unsafe because they impair my senses (or at least I feel that way). I have done several faceplants at 25+mph without a helmet and never suffered more than a small cut to my head (head injury wise). If you are going to smack your face into the pavement and need a helmet to prevent death...you're pretty much ****ed anyway.
