In this case, it's an argument that crash testing should be more expansive and thorough.
For example, if engineers are going to position the driver and passenger airbags for optimal crash test performance, we probably shouldn't just be testing with a male dummy in the driver's seat and a female dummy in the passenger's seat, as in the modern age women often drive.
If engineers are strictly designing to the test, there should be a suite of repeats, putting dummies that are male, female, fat, thin, tall and short in every seat.
