I would choose the word “cheating”.
This is just one from thousands examples, which shows how useless are all this fixed tests and rules.
Some EU cars had asymmetrical frame between bamper and longitudinal beams. Two spacers connected them in triangle with front angle placed in the point that devided car width in 3/5 and 2/5. It worked well for years (EU safety tests require one front crash-test with 40% cross-section between car width and crash block, this triangle helped to distribute force between two longitudinal beams perfectly), but suddenly US safety departament involved new tests with 25% overlap. And something went wrong:

This problem probably claimed many lives. Much more than VW diesel cheat. But it is harder to explain it with politics, so nobody is interested in such discission on tv prime time etc.
