A car pulled out in front of me when I was doing about 15mph along an urban road. I hit the side of it and flew over the top of the windscreen, landing on the road the other side. I had a few scrapes, a torn jacket, and a broken cycle helmet. If I hadn't been wearing one, it would have been my head that hit the road and scraped along it. Having said that, wearing or not wearing a helmet shouldn't be a matter of compulsion if the evidence is not conclusive. I will continue to wear one, though.
