So car drivers who don't wear cycle helmets on the road will show an increased ability to assess risk and will be less likely collide, which is why drivers have instinctively taken the decision not to wear cycle helmets. We're all really lucky that drivers have taken this magnanimous decision, because as we all know it's led to drivers having an enviable ability to assess risk correctly
Sitting in a lab playing cards isn't the same as the real-world stimuli of cycling on our roads, hence the the thread title, "Study finds that wearing a cycle helmet may diminish ability to assess risk"
Try telling a driver that they should wear a helmet too, since motorists injure their heads at a similar rate to cyclists.
They will tell you that they have seat belts, air bags and crumple zones. They clearly feel safe enough.
The death rate for more vulnerable road users went up when seat belt compulsion was introduced.
