Sounds funny, right?
Crash-test-dummies ain’t real people (for instance they don’t vote, Oh God did I just give them an idea!) they are instruments. Sensors are built into them to measure the forces exerted by a car crash. The lab technicians look at many factors and also want to determine if certain automotive design changes and evolving engine designs are making the vehicles less or more safe than last year and from years ago.
But if the chief instrument, that Crash-test-dummy starts being altered; heavier, lighter or other cosmetic changes (how heavy is an Afro?) chasing the new goal of appeasing activist groups then the database from past testing becomes useless.
Not as useless as Sec. of Transportation Buttigieg, but close.
