The car manufacturers have to publish results from standardized tests for range, fuel economy, battery capacity, etc.
The regulations for those test regimes are largely written by “industry experts” (i.e. lobbyists employed by the car manufacturers).
Then they program the engine management chips in their cars to recognize when the car is on a test stand and go into extreme efficiency mode.
There was a scandal about this a couple years ago with VW and they got some flak for it. By now it’s come out that all manufacturers do this, but the outrage is gone, it’s accepted as just another fact of big business.
