Not at all. As an engineer, you give me clear goals:
Meet these specific standards under these specific conditions.
I can do that. I will probably do that at the expense of performance under other conditions. That's engineering. that's not being a corporate apologist. Now VW took it over the line, by actively modifying the code to pass those tests, something that is forbidden, but without third-party review it's impossible to catch this sort of stuff.
What needs to be happening is that the software is audited by independent third parties, and there is random testing of actual road performance.
