Yes, and this is the reason that PA repealed the motorcycle helmet law
this year. The data just doesn't support it. Having said that, I still
always wear my helmet. The reason being that I believe I don't take
extra chances with it and thus actually am safer. However, across the
entire population, this just doesn't appear to be the case. Counter
intuitive to be sure.

I've said it before ...repeal all the helmut laws you want - just don't make
the taxpayers pay for your ICU costs when you quickly run out of insurance
coverage
