What evidence do you have to show a cycle helmet would have made any
difference?

Research shows cycle helmets can only absorb 70 joules before failing
and it takes around 1000 joules to crack a human skull.

They sound like very focussed Joules - bullet perhaps? ;-)

Bullet energy is usually specified in Foot-Pounds or Newton-Metres.
A typical 9mm pistol round has a muzzle energy of 500 joules.
