I believe selected individuals at VW probably need to be fired for intentionally breaking the law.
But, according to articles I have read that obstensibly were written by people that know something on the subject, the US EPA regulation involved is BS to begin with.
Accordingly, the idea that a huge and venerable company employing tens of thousands of people worldwide needs to be put out of business because of a dubious USEPA reg is BS too. It would be far better to put the USEPA out of business and return whatever worthwhile activities they might be involved in each day to the respective states.
I might buy TWO diesel VWs. I could care less about the EPA, but I love the idea of a car that will run on stored diesel fuel for 5 years after the last gasoline engine has choked to death on old varnished gas.
