I have spoken with many people on both sides of the issue, and my conclusion from the anecdotal evidence is that people who argue in favor of wearing helmets do so because they value their lives, and people who argue against wearing helmets do so because they are trying to justify factually that desire for the wind-in-the-hair feeling, and resent any effort to legislate or otherwise influence their behavior. (There are smokers who still claim that the studies the show that smoking cause cancer are all flawed.) I can accept an argument about how to interpret statistics but I have never seen any factual evidence that wearing a helmet is actually harmful, statistically.
Because you think the Hurt report is flawed I am willing to reserve judgement, but you are offering no facts to bolster your side of the debate.
Suggesting that helmets cause accidents due to fatigue, restrict hearing & vision is not evidence; it is a hypothesis. Is there any support for this based on accident statistics? I logged about 30K miles over a few years, all with a full-face helmet, and never experienced any significant fatigue or restriction of vision and hearing. (This was on a bike with a full fairing, BTW. Somebody riding a sport bike at high (i.e., twice the speed limit) speeds may have a different experience.)
Can you give at least one example? I won’t even ask for data, just tell me the state.
Get thee behind me, Satan. . .
