Right, given the way the last thread to mention helmets went (though became civilised towards the end - I've no idea on the two posts that were deleted right at the very end - let's come to an amicable agreement....
If anything comes up on helmets direct the people posting to this thread, where we can contain the argument (I've lined the thread in lead, submerged it in a deep lake in an undisclosed location that only a man with big facial hair and claws coming out of his knuckles could find, and left it guarded by dementors and young Tories).
I'm not pro-helmet
I'm not anti-helmet
I sometimes wear a helmet
I sometimes don't wear a helmet
I will ride in events where they are mandated
I will ride without one where they aren't mandated
I'm not convinced a helmet will save my life
I'm not convinced they cause harm in themselves
I'm not convinced people wearing them puts other people off cycling
I don't think sheriffs should use the fact someone wasn't wearing a helmet as a mitigating factor in their own death
I am against legal compulsion
A broken helmet after a crash is not proof that your head would have been broken
Falling without a helmet and not breaking your head is not proof that helmets are pointless
Yes, I know the Dutch and the Danes don't really wear helmets, again correlation, not cause of a cycling culture
I think that covers everything ;)
