Last time I thought about this I ended up comparing sprinting (Olympics, track and field) with sprinting (Olympics, velodrome).
The people on the bikes wore helmets, the people on foot did not- presumably this has some basis in what kind of injury could be the result of it all going wrong, and the probabilities therein.
I've crashed and never hit my head but I view a helmet as cheap insurance- it weighs 199 grams and it might do some good- why not wear it?
Even if my skull would cope with an impact the skin would not, and gravel rash on my head is something I'd prefer to avoid.
Hey ho- people will continue to do whatever they want.
What a pointless post! I'm going to get another beer.
This post inspired me to also get another beer, so it was not at all pointless.
