“But here I run into yet another data gap: the available research on whether car headrests have been designed to account for the female body is seemingly non-existent. This gap is hardly unexpected though: car design has a long and ignominious history of ignoring women. Men are more likely than women to be involved in a car crash, which means they dominate the numbers of those seriously injured in car accidents. But when a woman is involved in a car crash, she is 47% more likely to be seriously injured than a man, and 71% more likely to be moderately injured, 46 even when researchers control for factors such as height, weight, seat-belt usage, and crash intensity.”
