but... for eagl and all the others who simply bought the insurance companies bs and soundbites...
http://www.bikersrights.com/statistics/goldstein/goldstein2.htmlThis is a very complete study on the effects of wearing a helmet and fatalities and serious injury.
In short.. it states that Helmet use increases neck injuries.
speed and intoxication have the most to do with fatalities no link can be found between helmet use and prevention of fatalities (survivability) despite the myths and the "it saved my life" hearsay... there is no stat that says you are more likely to survive a serious crash if you are wearing a helmet. at fatal speed an intoxication...
you are going to die... helmet or no helmet. and...
If you survive.. you are far more likely to suffer a neck injury if you were wearing a helmet than not.
at best it is a tradeoff at non fatal speeds.. you get some minor reduction in head injury with a helmet but trade off for increased neck injury.
" Past a critical impact velocity to the helmet, measured by the normal component of velocity, helmet use has a statistically significant effect which exacerbates the severity of neck injuries.
Using the point estimates in equations 5-8 and the average weight of the helmet (2.70), estimates of this critical impact speed are around 13 mph. Beyond this realistically attained critical speed the energy absorbing ability of the helmet which is capable of reducing the extension- flexsion response of the neck to head impacts are surpassed. Under these circumstances, the inertial and post-impact response of the neck are intensified due to the added mass of the helmet and neck injuries result. An impact to the head whose normal component of velocity is 20 mph will increase the severity of neck injuries by around 10. Equations 7 and 8 also reveal that marginal increases in helmet weight do not have a statistically significant effect on the severity of neck injuries. This finding along with the acceptance of the zero constraints in equations 5 and 6 imply that it is the added mass of a helmet and not its specific weight that is responsible for exacerbating neck injuries. "
but.. regardless of the controversy... the choice of any trade off in personal safety should be just that..
personal....
Read the entire study and you will see that while a helmet may be a great thing for sports like football or riding a slow bicycle.. there is no clear cut advantage on a motorcyle and any of the speeds normally operated at.
