I’m inclined to believe it. While the HANS Device and other similar head-and-neck restraints do an admirable job of preventing neck injuries and basilar skull fractures, they put drivers at greater risk for closed-head injuries. Even though the head stops moving, the brain still moves inside the skull.
Yep. That last lick Jr. took looked hard enough to scramble your brains no matter what you had them encased in or restrained by.
