Not head banging, I've been quietly amused by this discussion for a while now, it's the way all the helmet threads end up.
It's a proxy subject (yes, the "r" should be there). Basically two pro helmet wearing members are arguing against two anti-compulsion members via the proxy of the claimed knowledge of A & E staff.
Whatever the form of pro helmet advantage arguing, it's always seen as exaggeration by the other side, so the fight is on!
Being on the anti side I always feel smug, knowing as I do that there will never be compulsion in my lifetime, either in the UK or mainland Europe.
Anyway, if A & E advances are so brilliant, shouldn't they be at least B & F by now, or even C & G.
