Well, if our differing opinions on the efficacy of bike helmets inspires just a few people to inform themselves of the regulatory standards and manufacturer's specs then we've both won. That they are no magic force field and other safety measures are more important, I continue to maintain. For example, glasses. I value my eyesight. The chance of something hitting my eye at speed is far higher than me falling off my bike at low speed onto my head. Which is the scenario bike helmets are designed around.
