All depends on how good of a rider you are, your background, where you live, where you ride... I welcome you to think what you want about my certainty of this... but i am certain nonetheless. There is absolutely no chance i'm going to let another car hit me. I just don't let it even become a possibility. When I ride my MTB on the street or dirt, i wear a lid. No doubt. Fixed gear in the city or road bike out in the hills? No way.
