Sorry guys, I didnt mean to be cryptic, I honestly thought you were just being deliberately sarcastic/sinical to the subject (which is a sense of humour I love by the way), my research (not scientific, just browsing the net looking for agruments both ways back in 2006...) truly was even. I dont mean the '10 reasons (not to/ why you should) wear a helmet, I meant actual results of studies ONLY.
This I summise, seemed about right from what I had read, and so I settled on this as the general tone seems about right to me, basically if your bike skids/you brake hard for some reason, and whilst doing your best to avoid it, you bang the covered part of your head on the kerb/tarmac, then that helmet will indeed make a difference.
Yep, I agree that there is indeed the risk of neck injury if you go 'head over heels', but most (not all) of my accidents from childhood to now have been sideways not forwards.
And I TOTALLY agree that there is absolutely no protection if another vehicle is involved.
However I do not accept that I ride more agressively because I wear a helmet. In my case I ride more aggressively because I want road space, otherwise I wouldnt ride at all.
For ref tho, and I agree with some bits of the 'Conclusion' from the DfT (extract below), but am not in any way in favour of the compulsory enforcement of helmets, BECAUSE I think so much of it depends on riding style, route, conditions, etc. But for me, on my route, at the times and in the conditions I ride, I believe that the is a partial safety advantage to wearing a helmet, in the same way I wear gloves (to avoid scratches to my hands) and long sleeve jackets (even in summer, to avoid arm lacerations). Obviously I could not promote gloves and long sleeves as 'safety apparrel', but I believe that they are JUST as important for protection as the helmet, every little helps.
Remember, I am a commuter, not a leisure cyclist!
Dft Helmet wearing Conclusion:
------------------------------
Section 9: Conclusions
What relevance does the evidence reviewed have for bicycle helmet promotion in Britain?
Unwin (1996), when considering the context of the British legislative system, has put forward four criteria which must be met before bicycle helmet wearing is enforced. These criteria are:
(1) There must be a high level of scientific evidence that bicycle helmets are effective in reducing the rate of head injury to bicyclists.
(2) The benefits to society and others of mandatory bicycle helmets must be convincingly demonstrated, mandatory bicycle helmets cannot be justified simply to protect individual adult bicyclists.
(3) There must be widespread agreement, ideally by a large majority, that the potential benefits of compulsory bicycle helmets outweigh the infringement of personal liberty and other disbenefits.
(4) There must be good evidence to suggest that compulsory helmet wearing would not make the public health benefits of increased levels of bicycling significantly harder to obtain.
Unwin has also suggested that mandatory bicycle helmets for children may be justified for their own protection.
The first of these criteria has been met. There is now a considerable amount of scientific evidence that bicycle helmets have been found to be effective at reducing head, brain and upper facial injury in bicyclists. Such health gains are apparent for all ages, though particularly for child populations (Section 3). Criterion 2 is less easy to demonstrate and must relate to a broader debate about the whole bicycling environment: bicycle helmet promotion and legislation needs to be seen as one part of a broader package of measures which enhances bicycling safety. The experience of countries such as Australia and New Zealand suggests that this process takes time. Barriers to helmet use can be overcome (Criterion 3). An infrastructure which promotes bicycling and provision for bicycle helmet is needed (for example employers, schools providing facilities for bicycle helmet storage).
In relation to Criterion 4 there is some evidence that legislation may have resulted in decreased levels of bicycling (for example in Victoria, Australia) but there are confounding factors and no clear long-term trends. Attention needs to be paid to enhancing the bicycling environment generally rather than concentrating solely on the individual approach of wearing helmets.
Finally, is there a case for mandatory helmets for children rather than all age groups? The UN convention on the rights of a child asserts that the child has a right to a safe environment. In the barriers and facilitators to helmet wearing section, we noted when children and adults bicycle in groups, children are more likely to wear a helmet if adults also do so. The role model effect of adults is an important factor in enhancing helmet wearing in children. It is also more difficult to enforce a law for one age group. Countries such as New Zealand or States or Provinces which have enacted universal legislation have attained high wearing levels. There may also be problems of enforcement if legislation relates to one environment, for example on-road rather than off-road because different sectors of a bicycle journey may encompass both on-road and off-road environments.
I think reason number 4 is the most compelling, to me it says that helmet wearing should never be enforced, it would be suicide to the cycle industry. I still think that conclusion number 1 is flawed, it depends on where, how far, route and conditions, time of day, and so on....
