If he was not wearing a helmet, the wing mirror could have missed him completely and he would still be alive, but without the brain damage.
or could have hit him anyway & spread his brain all over the road
Or if the truck driver had been looking....
if every driver on the road did everything there suppose to there would be no need to discuss any safety issues on the road, unfortunately not all road user do what is needed to keep everyone else safe.
I think it hit him in the back of the head
your correct, the point of impact was to the back of the helmet meaning that it would have him on the back of the head had he not been wearing the helmet & when shown on the television looked like it had been hit by a sledgehammer.
given the damage to the helmet caused by the impact i don't believe its unreasonable to assume the rider would have been killed or at the very least suffered a hell of a lot more damage to his brain, meaning the helmet did what it was supposed to do & prevented a more serious injury or possible death.
Whether he wears one everytime he rides a bike or gets paid by the helmet manufacturer to endorse this brand or any brand of helmet isn't the issue. The fact is that on this occasion he was wearing a helmet & it did what it was supposed to do & probably saved his life.
if a law is passed making it a legal requirement for a child to wear a cycle helmet while riding there bike & as a result of that law even one child survives an accident that otherwise may have killed them or left them disabled then its worth forcing them wear a helmet, unless of course those who are opposed to the law also believe that a childs life is not worth saving?
