Aside from during hard braking or in a shunt/crash, have you ever used the head-rest in your vehicle?
I've noticed many drivers, myself included, hold their body and head away from the head-rest. Conscious effort to use the headrest doesn't actually feel 'right' for driving - more akin to wanting to fall asleep...
