"Excuse me, but what more did the author expect the government to do?" It is not some outrageous expectation that the $8,000,000,000+/year, 14,000+ employee EPA and/or DOT independently verify the real world emissions performance of passenger cars and other vehicles. The cars were so grossly out of compliance that anyone with a ordinary field emissions testing machine could have caught it. If, as is very likely the c…
I still shake my head at this. If you wrote laws that said manufacturers of a particular thing had to do X, and expected them to adhere to it internally, and then paid expert testing facilities to validate those results, why would you EXPECT that you would have to do additional testing to validate the validation? And further more, why would you think that merely testing the test would lead to a different result? You…
No, that's incorrect in several ways.
There was/is no need for mobile equipment; simply deviating from the test regime on a stationary emissions test machine was sufficient to expose the defeat device. The defeat device worked by detecting the test conditions and defeating that detection is easy. Turning the steering wheel while testing, for example, will inhibit the VW defeat device. Simply running the test long enough (at least 26 minutes) would have exposed it with some common models.
Also, mobile testing is not 'a very difficult thing to do.'
For a time in the early 90's I was certified to perform emissions tests. At that time the actual machine fit on a wheeled cart; two men could hoist it into the rear of light pickup in a few minutes. I actually did that when we needed to move one to another site to replace another that had failed. That wasn't strictly legal (the units were certified for operation at a designated site) but the station owner didn't give a damn; he needed a temporary replacement unit and was not above fudging the paper work.
So nigh on 30 years ago any given wrench monkey with a power inverter could have operated an exhaust analyzer from a moving vehicle. Today the units are even smaller; now we have HAND HELD exhaust analyzers[1].
We've also had remote sensing emission testing equipment available for at least 10 years now. Output is detected as the vehicle drives by the unit; no need for anything on board at all.
Face it. There is simply no excuse. The regulator failed utterly. The regulator publicly admitted their failure without qualification. Your faith is misplaced and your rationalizations do not work. This is, assuming intellectual honesty, the point where you adapt your worldview, because the one you have is simply wrong.
