Lacking common sense? Have you read my last few posts? Common sense tells me that I should wear a helmet when I drive a car FAR more than it tells me I should when riding a bicycle at a mellow pace in relatively safe conditions. Once again, if you do not advocate wearing a helmet in other walks of life that are dangerous, do not try to do so in regards to cycling. It is like someone who is anti-marijuana but does not want to make alcohol illegal. Far more deaths and other problems are caused buy alcohol than marijuana but somehow basic logic is not something that everyone can exercise I guess.
