Did you seriously said the word "renegade"? Even if their superiors did honestly not know that they were loading fraud-ware in the vehicles, this is most likely the result of systemic social dynamics and perverse incentives. Mutually exclusive goals get set with no regard to the laws of physics or reason. Everyone who dares mention this self selects outside of the management hierarchy, so the whole chain of command becomes an echo chamber of overconfidence. Then, at the end of the day, something has to give. It was the emission control testing in this case. It could have been much worse.
