I bet all these hard people who don't wear helmets as some weird statement of freedom etc don't use oven gloves, never wear safety glasses when grinding steel, leave long leads on kettles so that their kids can toughen up and get used to the knocks. Same arguments that were about before seat belts were made compulsory. I have lived 61 years without a car accident so statistically, I don't need a seat belt using the above argument. I am only glad they made motorcycle helmets compulsory as one saved my life in the 1980s having rode tens of thousands of miles without one, it only took that one time.
No, a helmet is not going to save you in all cases but there are cases when it will and I would rather wear one just in case it is that one case I have thank you very much.
Let's face it, the only real argument about not wearing a helmet is vanity. That is your choice but do not try and make people feel they should not wear one just because you don't like the look please.
Oh do get over yourself. No one is trying to make you feel you shouldn't wear one if you want - just don't lecture those of us who don't or expect us to be impressed by irrelevant comparisons, half-baked arguments and the usual tedious mixture of "common sense" and paternalism. Helmet evangelists are boring.
