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

Whilst I like evidence, sometimes I am happy to rely on common sense. Common sense says that something with 2" of polystyrene that was tested to replicate some accidents will be better than 0.1mm of paper that was not designed or tested to protect heads. Therefore I will not consider the possibility of wearing a paper bag when I can wear a helmet.

Common sense suggests cyclists ride in the gutter. Stop using the phrase, it's stupid. You can't ask to discuss whether something is a good idea and then answer replies saying that you just want to stick to status quo because it's received wisdom. Again that's idiotic.

Ok so why not wear a down hill helmet or motorcycle helmet as they are tested to higher levels?
