Every is talking about how the headrest it's made this way for crash safety when it's blatantly untrue.
The headrest is designed to protect the heads and neck of the average man, not woman. Decades of crash test dummies have all been modeled on the average height and weight of the male body. This is why women are 47% likelier to sustain a serious injury in a crash.
Think of the where the headrest is in the optimal position to protect the driver, and then move that a few inches lower. Adjustable headrest often doesn't even go low enough to accommodate for many women. There is an actual cutoff height where you are just screwed and expected to die more. Not to mention the user error of forgetting to adjust the headrest from the factory setting of accommodating to the average male height.
This is why so many people are curled up like a shrimp. They are either: short, a woman, or the statistically deadliest of all, both.
