I will look at the annual cost, but I'd bet that the costs saved by increased helmet use would be very low. I do note that of the specified categories of lifetime user costs, pedal cyclists is the lowest, including pedestrians. So perhaps helmet technology is better utilized elsewhere?

And no, I don't think my reading os the ANSI risk table that you provided is incorrect, by your analysis, bicycling would fall into the occasional occurrence, catastrophic consequence category, regardless of the use of protective headgear or not. Therefore, the activity is occupationally unacceptable by your analysis and selected methods of evaluation. I disagree because I do not find bicycling to carry an unacceptable risk.

But in the bottom line John, How much is a helmet worth to you? If you lost yours, how much would you be willing to pay to replace it? Mine value would be quite low, as I believe the insurance value of bicycle helmets is quite low. Yours is higher. Thats OK, but my main disagreement is with those who insist on telling me to wear a helmet.

We are in agreement that there are much better ways to mitigate the risks in cycling, but we seem to disagree how much risk there actually is.
