"what people are asking the EPA to have done was load up vehicles with mobile emissions equipment (which is a very difficult thing to do, by the way): 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.
