From the article they cite at the top in an effort to claim that crash tests since the 1960's have only used male dummies.... ”GM also needed a test device to simulate a small female for testing of driver airbags. In 1987, GM transferred the Hybrid III technology to a dummy representing a 5th percentile female."
Not saying that a true representation of the female body isn't needed, just that this specific article is hyperbolic in its wording and is misconstruing it's sources to produce a desired narrative. Maybe best to find articles with a more nuanced, fact based reporting
I listened to a podcast episode about this, I believe it was 99% Invisible. The female dummies that have been used in the past are basically just scaled down males. That's not exactly ideal.
