It’s interesting as far as it goes.
I mean in terms of a gopro and it’s mounting hardware presenting a increased risk of penetrative damage to the helmet’s shell, well lumps of plastic are probably way down the scale when compared to other objects (Rocks for example) which a helmet could be reasonably expected to strike. If anything the adhesive fixed Base of a gopro mount would probably act as a load spreading device applying the impact force over a couple of square inches rather than a point loading.
As for the rotational injury theory, that may hold some merit, only Schumacher’s injuries have consistently been reported as the result of a blunt impact trauma with a rock. Why after all these months would his doctors suddenly realise that they were dealing with a rotational injury not the results of direct impact?
“oh shite his brain was fine all along, why didn’t we check his neck sooner?”
It’s just some vague notional idea turned into a speculative article to give technophobes some shite to harp on about…
Gopro didn’t smack his head in gravity an a rock did FFS!
