On a whole I think the safety-movement is very exagerated and that if we who are promoting cycling helmets were consequent we should also be wearing them walking and driving.
Well, I think that helmets look terrible, so I only wear one of those leather hairnets while cruising around town on foot. I can't stand walking around with a big piece of styrofoam on my head, I'd much rather have a fashionable padded leather g-string strapped to my dome.
