bonj said:my view is that they can't do any harm, but they obviously CAN do a lot of good. I don't think anyone doubts that they can't absorb ALL of an impact, but absorbing some of an impact is better than absorbing none of it.
The "if I crashed i'd be dead anyway" attitude is stupid as there might be an impact that's just of the right magnitude for a helmet to make a difference.
It was more the fact of reports of them being more dangerous with rotational impacts that was concerning me. If it was a case of questionable benefit, but nothing to lose, I probably would wear one.
