Ridden your bike behind a diesel truck lately? They still suck with
massive output of particulates. There are diesel designs that are very
efficient and clean-burning, but they are not in widespread use. The
University of Minnesota has a diesel development program that has
resulted in diesel engines with very low emissions. I spent a very
interesting hour talking with one of the lead engineers in that project
a couple of years ago.

You can't pinpoint current air quality problems from a single source or
even a single nation. There are lots of contributors. Cars. Trucks.
Coal fired powerplants. Industry.

At this point we are still buying into the illusion of "profit, profit
uber alles" as the mantra for our economic model.
