Lowest part of neck to higheat part of the headrest? Sounds like the before times when peoples necks snapped in acidents because nothing stopped their head shooting backward
Yeah, the headrests in cars are angled forward because it's the safest in the event of a crash. Unfortunately, that means that the headrests are generally uncomfortable. The back of the head should be resting on the headrest; the neck should NOT be resting on the headrest unless you want to risk permanent injury or death.
If you have an accident, whiplash is partially countered by a seatbelt, but if you do have an accident, the severity of your neck damage will be dependant on your resting posture.
With a correct posture, there is less deviation in how your spine bends.
In any case, headrests are adjustable, make sure it's set correctly. Unless your posture is perfect, changing your ergonomics will be uncomfortable.
Whiplash is from your head moving more than your neck can compensate for. The headrests are designed to prevent excessive backwards movement of your head to help your neck not get completely over-extended. Heads are actually quite heavy and there are a lot of very important things inside the neck that you don't want getting fucked up be getting jerked around too much. The muscles in your neck can only do so much in a high-velocity situation like a crash.
