I think in Europe the NOx effect has been deliberately overlooked or downplayed in official checkes, because the lower diesel consumption is important for households and businesses especially in a time when most economies are ailing. Governements don't want to load their economically weak voters further by penalizing diesel cars.

Is this responsible? NO. The devious logic might be that people with asthma are less in numbers than those saving money from diesel fuel consumption!

In the USA with cheap petrol I cannot imagine how a household would choose diesel so the authorities can be tough on diesel.
