Impact duration up to 8ms can’t be important. The brain is sloshing in fluid for this reason. It’s not stopping in anything like 8ms anyway.
I concur with the conclusion that it’s worse than a helmet. Not sure at all why you think it wouldn’t help in an auto collision at all. Less than a football helmet let alone a motorcycle helmet (built for high vs low speed collisions).
