There's a reason all crash test dummies were male until last year

Last year, government regulators made female crash test dummies a mandatory part of crash evaluations for the first time in collision evaluation history. Until then, manufacturers had been content to use dummies patterned after the average American male. Safety advocates have argued for years that designing for male occupants present problems for smaller females. When airbags deploy, they're meant to strike occupants in the chest, but smaller individuals may instead be hit in the chin. If that happens, further head and neck injuries could ensue.
