Just for fun I took the graphs of head injury rates amongst cyclists in
Western Australia and New Zealand and removed all traces of dates etc. I've posted them at http://www.cycling.raven-family.com/Helmet%20Graphs.jpg Without the hints on the original graphs, can you spot when the mandatory helmet law was introduced? Answers in ticks from the left on a postcard without cheating and looking up the originals. Thought it would make a good challenge for the Swampmonster to ask her to point it out if the opportunity ever arose. Tony |

Been there, done that. The really striking thing is that the Australian weareing rate apparnetly went from around 30% to around 80% in the three years up to and including compulsion. Can you see any justification for 90%, 88%, 85% or 69% efficacy in that chart? Guy -- May contain traces of irony.

Answers in ticks from the left on a postcard without cheating and looking up the originals. Here's a spoiler for the australian graph showing the percentage of crashes that result in a head-injury: http://agbu.une.edu.au/~drobinso/ozdoc.html (It looks similar so I assume it's where you got your graph from, Tony?) The answer being that helmet compulsion was introduced 2 ticks from the RHS, just before pedestrian head injuries fall and cyclist head-injuries rise. AC |

I think, in dedication to their cause, C&S should wear enough helmets to protect all of us. After all their first priority is safety and they can be far more certain that people will be safe that way than trust to the vagaries of whether individual do or don't wear helmets. ;-0 Tony |
