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

I'm not surprise, more than half the nodder in London take even more risk when riding because they're under the illusion that they're 'safer' due to wearing helmet, day-glo jacket, glove etc.

you shouldn't be riding aggressively just because you got helmet, jacket etc. ironically you're more at risk to yourself than not wearing helmet, day-glo that force you to take it easy.

As for helmets, on both times I have been knocked off (both times without prior warning - rear ended & then side swiped) I have landed head first - natural self preservation instinct making me land on the least important bit - I have been wearing a Giro Ionis that has compressed perfectly - the last time, the helmet compressed in by approx an inch and I was told by the ambulance crew, that but for the helmet, I would have had a fractured skull....

as ever your fate is in your hands to an extent - ride like a c#nt, you will get knocked off sooner or later, hit your head without a helmet - it will hurt
