Okay so I think some people might need a course on why headrests are designed this ungodly way...
during a rear-end collision or sudden braking as the vehicle makes a sharp forward-backward movement. Without the angled headrests, passengers may suffer spine misalignment of spine-related injuries due to sudden movements. The headrests also keep the spine in position with its “forward-looking” design. This stops the pain and other symptoms associated with a misaligned spine.
Your headrest is probably to low... If you lean back into it your chin should go down towards your chest... This is what protects your neck along with the support from the headrest...
