Concluding remarks

My purpose is not to dissuade people who wish to, from wearing cycle helmets. They do, I promise, work a little better against a flat surface, than the Court decided in the case I cited above. After all the Snell B-90 standard called for four impacts on each test sample, two of which were tested against flat surfaces with an impact energy of 100 joules each. The tragedy is you cannot buy helmets to this standard any more. Manufacturers prefer the easier standard that they helped to write.

Rather my purpose is to illustrate that the whole cycle helmet issue contains many hidden issues of which most researchers are quite unaware.

Referring back to the Court case mentioned early, the very eminent QC under whose instruction I was privileged to work, tried repeatedly to persuade the equally eminent neurosurgeons acting for either side, and the technical expert, to state that one must be safer wearing a helmet than without. All three refused to so do, stating that they had seen severe brain damage and fatal injury both with and without cycle helmets being worn. In their view, the performance of cycle helmets is much too complex a subject for such a sweeping claim to be made.
