you have a built in natural "slip plane"....externally its called your hair and sweat, and cerebral fluid internally.
if rotational deceleration ON IMPACT were truly THE issue, we would run perfectly spherical helmets which would have zero lips/ridges, or edges, and break away magnetic visors. All of those features serve to limit rotation on impact. to my knowledge, only Arai addresses it from a shell stand point and Fox address it from a visor standpoint (both only in the mx world). It is not addressed at all in the MTB world.
if you can get a concussion without ever impacting your head, then the slip plane is not a solution. you can get a concussion from whiplash.
the reality of the matter of MIPS "success" is twofold:
1) For any given brand model, the most attractive colorways are the highest price. MIPS is also on those colorways. Vanity has already justified the upcharge
2) With no data, we cannot prove that it helps. But for the upcharge, nobody can claim that it hurts....and after all, isnt your brain worth an extra "n" amount of dollars. SOLD! we've all been marketed to!
