I had that suspicion before for sure. For example I have seen bodybuilder types with apparently strong looking necks get knocked out fairly easy. You would think with such big muscular neck they could take a punch better but this puts this all in question.
And it's funny that you should mention how to absorb or prepare for a bump in the road while driving. I was in the passenger seat recently and the driver completely didn't see a huge speed bump. I gave the heads up about it but we went through the bump at about 25 mph or so. I instinctively did what you described I moved my upper body forward away from the backrest and this did take from the impact.
