Do you have any evidence that any of these crashes that the victims claim the helmet saved their lives/brain function would have had the exact same result sans lid?
Unfortunately there is zero chance of proving the result either way, as replicating the conditions of the event exactly is impossible. It is however possible, with test rigs, to prove the addition of a safety device to the equation will reduce the severity of the physical forces that result in the fatality/trauma.
It's all a matter of risk management, whether you're talking about helmets, seat belts, abs, srs, not smoking, reducing speed, washing your hands, getting out of bed in the morning. If it MIGHT save me from dying, but might be mildly uncomfortable for 5% of my ride, that's a pretty good deal. Hell, what's the chances, and where's the evidence that the brace position will save your life when your commercial flight plummets to Earth from 30000'? But it's still standard procedure.
Wearing a helmet will [b/]reduce[/b] the risk of death./tpd Wether your casing a 40' road gap, or washing out on a 4km/h corner.
I couldn't give a rats arse if he never dropped his bike, ever, or becomes a vegan from a near fatal blow to his melon from falling off his stationary bike at the bottom of a 1% grade fire trail. His choice, but why ask if it's smart, then bleed like a virgin on her wedding night to John Holmes, when he's told its not. If I want to her a question from someone who's already made up their mind about the subject, I'll get drunk enough to speak to my wife.
