yeah i don't think i could even wear a flip helmet, they feel too vunerable
(not so) funny story though, my friend almost died because he was wearing a seatbelt. He was in a taxi, it emergency stopped, the seatbelt cracked his sternum. His chest cavity got infected, he then got septecemia, (spent several weeks in hospital), and one of his retinas detached, leaving him mostly blind in one eye. It was a 1 in a million though though.
