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.

It makes more sense to use a driving helmet.

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.

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

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.

I assume you always wear a helmet, not just when cycling.

That is why they have killed several children in playgrounds.

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

That would depend on what you expect the hemet to do.
By all means cycle in a full face motorcycle helmet if you wish. It will protect your head but will be uncomfortable. You might want to do some research on helmets and how they impair cognitive function.

But what helmet to buy?

What are the British Standards that such a helmet has to meet?
