It's a crap experiment. No control group, shoddy statistics, tendentious assumptions, etc.
From the sort of standard mortivatiional psych unknown to engineers, there is a difference in attitude and execution, including in risk compensation, between those who voluntarily wear helmets and those forced by law to wear helmets. I think the first group will be aware of the possibility and guard against it. But proof is another matter entirely and will take a good deal of money, manpower and time, not one of these el cheap hit and run studies.. What's more, since helmets are so contentious among cyclists, an additional element in the matrix, or for prior exclusion -- how is yet another matter -- is whether subjects believe or not in the efficacy helmets. Every cell added to the matrix makes the study bigger and more expensive to achieve an equally reliable result. Given the presence of willfully incompetent or crooked "statisticians" like Krygowski on both sides, whatever test design even a top professional comes up with will be tiresome contested by the clowns on one side or the other..
