For these women, the consequences of living in a world built around male data can be deadly. The reason this has been allowed to happen is very simple: cars have been designed using car crash-test dummies based on the “average” male. The seatbelt test, one of the frontal-collision tests, and both lateral-collision tests all specify that a 50th-percentile male dummy should be used. There is one EU regulatory test that requires what is called a 5th-percentile female dummy, which is meant to represent the female population. And secondly, this female dummy is not really female.
