Re: These is no such thing as a "Defeat Device"
If, by chance, your are refering to my posting, let me point out that I have never tried to avoid the obvious truth, and never claimed any excuse for the moral or criminal failure of VW (management or engineering).
I'm interested in both the technical and systemic origins of crimes, and simplistic, misleading, or just plain false explanations may be entertaining, but they don't help me.
For example, (from above) "detection routine which recognizes which test is being run and setting the engine MAP explicitly to a set of values which are used only in a test."
That is a false description, so it doesn't help identify the technical or management failures which lead to this crime.. Cheap and careless reporting leads to false descriptions like that I just quoted, and so cheap and careless reporting doesn't help identify the technical or management failures which lead to this crime.
Hiding behind semantic justifications like "a device is a system" doesn't help either: there is no system specifically dedicated to cheating, and pretending that there is, while understandable given the poor level of reporting and edititing demonstrated here, doesn't get you any closer to punishing those properly responsible for the crime.
Which reminds me that no, I wouldn't take anything that VW says on face value, even if it was accurately reported in the comments section of a news source, acccurately derived from an English language press release. (Which, with respect, doesn't seem to be the case here).
