Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

Nice rundown there MDCC. This bit especially:

Taking all the evidence together, including evidence of the health benefits of cycling and the fact that helmet compulsion puts off some people from cycling at all, and also taking into account the general libertarian principle that only an enormous public good justifies state impositions on private behaviour, helmet compulsion is a bad thing. The costs and benefits of helmet use should, as with any product, be presented honestly, leaving people to draw their own conclusions.

Can we just collapse all of this thread down to this morsel and lock it, please?
