Reply to comment by Diligent_Nature 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

Not just for water. Subzero Celsius means rain turns into snow, and also that windscreens start freezing, thus requiring pre-heating to de-ice it.

Of course.
But the comment I was replying to also mentionned to use “antifreeze” to avoid pre-heating, as if the problem with pre-heating was liquids.
It’s not.
The problem is the snow, which starts at 0 Celsius.
