Ok I'll join in the silly game:
Why would a modern light duty diesel engine be bothered by cold starts / short runs any more than a modern spark ignited gasohol engine?
Are they made out of different materials or something?
A short drive empty truck light duty diesel should be using so little fuel it shouldn't be bothering it's after treatment too bad.
Abrupt throttle increases rather than letting the engine build manifold pressure = "smoke" so if you are always romping on the throttle "rolling coal" (if you didn't have a coal filter) you will load up the DPF with coal and it will need to regenerate sooner rather than later.
