While Dieselgate was certainly a scandal, it was more significant as an example (now known to be one of many) of cheating than as an act of NOx pollution. The NOx standard for an average heavy-duty truck/bus allows (by my math) 3.8x more NOx per hour than VWs were emitting before the scandal and subsequent fixes. There are more heavy-duty trucks and busses (16 million) on the roads today in the USA than there were non-conforming TDI engines sold in the entire world (11 million), and the trucks run many more hours per day.

I'm not trying to diminish the severity of VW lying to the public, but we shouldn't hold Dieselgate up as a unique (or even particularly egregious) act of pollution.

The calculus may be different for Europe, but they still have 6 million trucks and busses on the roads.
