Question for folks who make helmets or believe in their powers. Someone tweeted this to me: "I have two friends who have serious brain damage from getting hit by cars while riding bikes (would both be dead without helmets)." It's a sentiment I've heard many times. Please explain.
Like if you have a serious brain injury, how does that provide evidence that the helmet worked? And if you got a serious brain injury with a helmet on, where is the evidence that its presence prevented death? Especially given how many people die with a helmet on.
Instead of having a rational conversation about what helmets can and cannot do, it feels like we have mythology to debate. Like maybe helmets are effective to a point, and then there are collisions where a Styrofoam head covering cannot prevent severe brain injury and/or death.
