They make cars that are very safe from a testing protocol perspective, but cars that might also fall off their performance cliff quicker in some real world scenarios where the energy input is just a tad higher.

They engineer to robustly pass tests, seemingly without a lot of consideration of "beyond" the test. It's not uncommon for most OEMs to target the test metrics, but you can still make design choices along the way where you may recognize with EJ when there is a "design cliff" and you may avoid it.. if desired.
