It seems like you're using "women" as a proxy for "smaller people". Children and small-statured men are just vulnerable as women in crashes. Regardless, we now do crash tests with a variety of body types.
A 5-foot man is just as vulnerable when being hit by a car as a 5-foot woman, and obviously children are much more vulnerable than grown women when being hit by giant vehicles.
