About those five star safety ratings

Or, alternatively, Congress, the NHTSA and the Insurance Institute vs. Physics and Engineering, part ???

What do I mean? Evidently, all those five star safety ratings on compact and subcompact cars don't really mean much when they crash into something larger than they are--like a tree or 95% of cars on the road. Seems like Isaac Newton had it right four centuries ago when he formulated

F = M A

I keep dreaming that one day, Congress will listen to actual engineers before passing regulations, but since apparently they can't even be bothered to read the laws before voting on them, I'm guessing that understanding their implications is way above their pay grade, sad to say.
