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.


How many joules does it take to cause a catastrophic bleed on the brain,
though?

I'm not sure what you mean by 'before failing'? Does that mean the
helmet cannot absorb more than 70 joules altogether? Or it cracks but
still absorbs some of the impact?

And clearly helmets vary.
