I love other people to check out my shiney helmet!lol (sorry had to bring it to that level!). I agree that it is freedom of choice, but I would personal feel unsafe without one on when riding. It gives me the feeling of security which intern boosts my confidence wey high because it is something less to think about, I don't have to constantly consentrate on "If I fall off hold your head off the ground" or something along those lines! You know what I mean?
