I could imagine refineries, shipping, etc. of fuel to release more pollutants than the cars themselves, but those operate further from populated areas, so the health risks are smaller.

Does anyone have comparisons between HC emissions and NOx? Knowing how toxic HC emissions can be, the emphasis on NOx is a bit surprising to me when NOx is less persistent in the environment.
