That is why the EU has started testing emissions while the vehicle is driving on public roads.

Almost every automaker has been caught cheating: Ford, Chrysler, GM, Toyota, Honda, BMW, Mercedes, Hyundai, Renault, Peugeot...
VW was just the most bold about their defeat device. The car actually turned off emission controls if it didn't sense that the car was driving on a dyno. They rest kind of work around the edges in grey areas.
