Is the wind chill more than marginally relevant to a car?

People lose heat through evaporation, which is worse if there's wind.

Objects don't, and normal wind speeds are usually well below driving speeds anyway.

When the car is stopped and trying to warm the battery so it can begin fast charging, the wind makes the vehicle surface dissipate heat better. Which you don't want. But... batteries are fairly insulated so wind chill probably has a marginal effect at best. I was just emphasizing how much colder it was in Chicago than in Oslo :)

The magic of water in clay makes objects cold, like the Olla pots for water or https://en.wikipedia.org/wiki/Pot-in-pot_refrigerator

I have no clay cars sadly, not sure how ordinary cars handle wind chill.

My first vehicle in high school was a diesel pickup in Alaska that wouldn't start at -20F.

Wow, that is almost as cold as Harbin!
