There are a few things that we should be considering that the SJWs have ignored either through ignorance or deliberately because it doesn't fit their agenda.
First, the EPA set out requirements that the engines had to pass on a STATIC test. There is no dispute that they do, there is also no requirement for continuous running tests. VW has met the letter of the law
but maybe not the spirit of that law - but then whenever does a government even consider the spirit of the law.
Next, the climate change/eco scam is a multi billion $/£/€ business, so much so that those 'eco-warriors' had the Australian PM removed because he had the temerity to question the Aus Bureau of Meteorology's fiddling of the temperature records
Also the Obama regime is ending soon. Both of these lead on to...
The climate change/ecofest jamboree in Paris at the end of the year and the distinct possibility that it will be a flop that will lead to the gravy train hitting the buffers and all those wonderful grants and carbon trading profits evaporating into thin air.
All you have to do is look at the timing of this 'expose' when you consider that it has been open knowledge in the industry for years and ask 'how does this fit in with the Paris meeting' - oh look, they are not following the spirit of the law therefore we must have more global laws regardless of what the people think.
