Reply to comment by 403Verboten in 30 minutes of car preheating in sub-zero conditions produces as much particulate emissions as driving 97km in a gasoline car, or 20km in a diesel car “These findings do not suggest to stop preheating cars; instead, we could reduce the emissions by using similar methods that are in place for engine” by giuliomagnifico

I lived in an apartment in the downtown of a small town. Semis used to idle outside my building for 1/2 hour while waiting to unload stuff for the stores on the first floor. The fumes and the noise were terrible. If it were illegal, I definitely would have turned them in, even if there was no cash involved.
