Looks like the trade off is, breathing safe exhaust here, screw the rest of the planet.
26% of the US population lives in the 10 largest metro areas
56% live in metro areas greater than 1 million people
67% live in metro areas greater than 500K people
76% live in metro areas greater than 250K people

The vast majority of the US population lives in urban areas

Not just the DPF, the EGR, the injection timing program that "preheats" the cylinders with a few tiny injection pulses before the main injection events. The "preheating pulse" decreases fuel economy, reduces engine noise, reduces peak combustion temperature and pressure, reduces NOx and increases soot.
Which is why we need emission inspections in every state
