So what are you trying to say?
a. The HANS was of no relevance as the car punched its way into the barrier too far.
b. The HANS allowed the head to go too far forward.
I wasn't clear, I was drawing attention to the strong evidence that the helmet made contact with the matting and so could have contributed to his Basal head injury, in other words it may not have been that HANS failed to do its job by preventing the head going forward. The assumption is that a violent rearward blow can cause a Basal fracture.
Slisoslid, my apologies if I misread your personal involvement in flight safety, as I read your original comments collectively to be anti helmets and suits.
Perhaps you will reflect on your comment that I don't take flight safety seriously, since I have fueled the question of adopting a Hans like device for helicopters and incidentally couldn't be more proactive and outspoken in respect to education of the media business in respect to flight safety whilst filming.
