Actually the story came from the "Guardian" & Huff reported it. Point is regardless of got caught or cheating, many other vehicles pollute more than VW. What's actually good here due to VW this has exposed other mfg's. Now everybody will have, to correct, which will be good for the environment. Also this shines a light on, how regulators have to appease industry, so as to get some regulation, the appeasement allows loopholes. Also the other cars mentioned exceeded permissible NOx, which is fail.
Who put pressure on who to allow, these non real life testing procedures to be a valid form of testing?
The goal is a cleaner environment, not pressuring regulators to allowing exotic testing, due to industry pressure.
