Rigged tests mean diesel pollution levels are higher than thought. But is diesel that bad? And how will it affect you?
The carmaker Volkswagen has been forced to admit that it falsified emissions tests run on its vehicle engines. It did so by employing special technology that only turned on during test conditions, and which artificially lowered the amount of pollutants produced from its diesel cars. This led to vehicle licensing authorities, which conduct the tests in order to protect public safety and cut pollution, believing that the engines were much cleaner than they really were.
