I don't know where that trauma porn poster comes from but you would have to read it carefully to see what they are saying. They have numbers of deaths and serious injuries but no number for those with permanent brain injuries and no justification for the 40% figure.
They don't say how many of the 11,000 deaths could have been saved, most fatalities involve collisions so severe a helmet would make no difference. Of the 30,000 serious injuries how many involve permanent brain injury? Thankfully it is a very small number.
