Re: ...due to the actions of some lone shark at VW. ????
"EVERYTHING is specified, designed, signed off by lots of senior managements"
Yes, but do they always understand what they're signing off?
Mind you, I'm not arguing with the general thrust of your argument. Lone shark defence is rarely plausible. In this case even less so. VW management has taken credit, not to mention bonuses, for increased profits. It's not unfair to ask them to take responsibility for any dubious methods used in the way to profit. Found a cheap way to meet emissions target, have you? Have you?
