Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

Not sure if this is the best place to put it, but has anyone seen this pro-mandatory-helmet campaign?

This is Gareth's story.
Gareth was cycling home on January 16th 2017 at 8am.
He was wearing a helmet, had bright lights on the front and rear of his bicycle and on the back of his rucksack, he also was wearing clothes with reflective strips on. He was doing everything right as a cyclist to stay safe.
A tractor driver failed to see Gareth before it was too late. He hit Gareth from behind, killing him instantly.
Gareth's helmet was destroyed on impact, resulting in a fatal head injury.
If Gareth stood no chance with a helmet on, what chance do others stand when not wearing a helmet?
Our aim with this petition, is to bring in GARETH'S LAW to make it a legality to wear a helmet whilst cycling anywhere on any surface and to have working lights on the front and back of a bicycle, which must be on from dusk til dawn and in poor weather conditions and less than good visibility.
Seat belts must be worn, to save lives, as the law states.
It needs to be the same for cyclists wearing a helmet and appropriate lighting.
If we can prevent just one family going through the trauma that we have, this will be 100% worth while.
We see too many cyclist on the path and road not wearing a helmet and not having working lights on their bicycle.

It strikes me as a very absurd allocation of energy, considering that the unfortunate victim was using everything the campaign seeks to enforce, but still died. Isn't it obvious that the real issue was the tractor driver not looking?
