And theres not much of a correlation with actual injuries-in-use either.
What is happening on the lab dynomometer isnt being reproduced in the live environment, or if it is it is not demonstrably leading to injury reduction or mitigation.
The only proven means of protecting your head is to improve your riding and road skills, and thus take proactive measures to avoid parking your head on the tarmac. It was always thus, and remains so.
While the helmet did protect the head of the chap where I’m from, who was crushed by a passing vehicle against a parked one, it made no difference to his survival. Nor did his level of skill. But then every time you get out of bed, it’s a coin-toss whether you make it back into bed again.
Wear a helmet, or don’t. But don’t delude yourself it will ‘keep you safe’. On average some 1% of the population die each year. With a population of 70 million, that is about 700,000, making it a 1 in 700 million chance of dying. 80 cyclists died on the road last year out of 600,000 total deaths, one death in every 10,000. Sacrificing to the Gods of Cycling is just as likely to ‘keep you safe’.
