Reply to comment by N00L99999 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 mean, that's fine. The way you said it didn't make much logical sense to me.

I'd have told him that it's not about the engine's water freezing (or not), but rather about warming the engine to deal with the environmental effects of freezing water and general cold. Defrost the ice on the windows, stop fogging windows, and the fact that most humans aren't happy in freezing temperatures. Skip the part that reads like it's not about water freezing, but that it's about water freezing.
