How to stop automakers from cheating on emissions tests

There is a long and sordid history of car companies using “defeat devices” to skirt government pollution and other mandated regulations mainly because the incentives to do so are significant. The first of these devices turned off the newly mandated emission systems when people used the air conditioning.

Recent devices sensed when government devices were attached and calibrated the engine to perform in a manner consistent with what the government considered acceptable results. The car manufacturers are incented to do this because of the need to meet the challenging regulations set forth by governments world-wide with regard to things like emissions and fuel efficiency. These are difficult problems to solve and one way to solve it is to give the government what it wants, just not in the way it wants it.
VW and Fiat Chrysler are just the latest to come up with ways to manage the demanding and at times, conflicting government regulations imposed on them by countries.
