This is barely suitable for the forum, but since it's being mentioned elsewhere and we might even (!!) be able to avoid rehashing the whole debate in depth:
http://www.wrongheaded.org.uk/ - the fight against helmet compulsion
The UK's first helmet law goes before committee on March 10th. There is a petition - please take ten seconds of your life - as well as other details on the site.
There are only a few days - such is our wonderful system - so please don't sit on your hands, if you're inclined to be sympathetic towards choice.
