So far on this thread we have had the most appalling mix of inappropriate stats I have seen for some while. The worst being the quite misleading stuff on the injurylawyers4u.co.uk . When I get a few dozen hours free I might unpick some of it in detail. As a taster the CPSC data probably includes head injuries (cuts and grazes) as well as internal injuries and has no severity scale. The CDC data only includes formal team sports so is not much help here. The injurylawyers4u.co.uk data irrationally mixes formal sports with everyday activity but doesn't measure cycling against walking or car use. Their selection of worst case data to draw conclusions is unforgivable and the conclusions they draw don't follow from the data they have. The Headway data, like the CDC data, is interesting but doesn't help with a discussion on cycle helmets.
None of that can in anyway lead to the claim that
enforced compulsive use might not be a bad thing for cyclists
The lack of clear statistical support for helmet effectiveness is the main reason for opposing any move to compulsion.
