New ECE regulations mean a bump up in price and in safety

I have a decent size chip on my windshield, I can just imagine the impact on my shoei visor let alone an open face helmet.
Like everybody else, I knew the helmet impact can cause brain injury but I had no idea about rotational force.
Brian Van from SportBikeTrackGear was showcasing the MIPS technology that was in Bell helmets which I initially thought was some sort of gimmick, not any more!
the video below is about bicycle helmet by Bell but it explains the Mips technology.
this is very sobering to say the least
here is Van the man. fast forward to 8:21
 
Video 1:
Potentially reducing the rotational energy transferred to the head? That isn't a very strong statement (and it was probably the best they could do as it was a marketing document).

Video 2:
What reduces the energy? I can see the plane slipping, but it moves about 1/2" and then appears to bump up against a solid stop. If your head and EPS were attached and the shell is allowed to slip with some resistance (think of a slipping clutch but you probably need a spherical shell) I am all over this. I don't think MIPS will hurt, but I really don't see any difference in actual protection. A typical liner will probably allow your head to move 1/2" with respect to the EPS already.
 
MIPS is a patent skirting copy of 6D's system. I'm a fan of the previous work (Mountain Cycle) of 6D VP of Product Inovation Robert Reisinger, and will most likely buy one of their helmets when my Moto 8 nears it's best before date.

There already exists a safety standard for face shields, VESC 8 but not many manufacturers seem to bother.
If the shield passes, its marked accordingly.

Motorcycle Helmet Face Shield Performance Standards Explained

We have covered helmet certification standards in the past, but there is another part specific performance standards apply — a motorcycle helmet face shield.

A helmet has the potential to reduce injuries in an accident....but it may not....yet we all wear one hoping that it does. But if a friggin final destination steel rebar piece comes through my visor at 100km/h it will NOT reduce my injuries.

Your questions about video 2 are basically that you don't understand/they haven't explained it, but that doesn't mean it doesn't reduce damage. The plane of energy is what is important with mips. A direct impact at 90 degrees to the helmet will not be reduced by MIPS. The energy of a glancing blow may be reduced. That's all they are looking for. "I really don't see any difference in actual protection" is just an opinion, and opinions are not science.

Explain to me what I'm missing? The glancing blow allows the Eps to freely rotate ~1/2" wrt your head and then appears to come up against a hard stop. Very little energy was dissipated in that movement. If there was a viscous layer, it would dissipate some energy and stretch the rotation over a longer period of time which would reduce peak forces.

Please quantify your value of "very little" and "some" energy and what scientific method did you use? PTOOMA?*

FYI i do not have a MIPS helmet.....but I probably should (since they pay me to post this sh!t)
