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

On my commute I find the majority of people wear helmets. If I stop at lights and look around at other riders. The non-helmet wearers are now in a minority in London. Does anyone else find this to be or am I just seeing things? Are there any stats on it?
