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? ;-)

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?


Depends on the incident and circumstances, of course.

And clearly helmets vary.

Indeed - and I at least find it difficult to tell what's what (I use an
Aldi own brand). I gather this is a good guide:

Common sense tells me that a cycle helmet can help in certain
circumstances - and it's worth wearing one on that basis.
