Norway says "hi".
Honestly, if you have grave concerns about electric vehicles and the cold, you haven't been looking around lately. Norway's car sales as of January 2021 are 50% electric. They seem to be doing just fine over there in the cold and bad weather with their electric vehicles.
Co worker has a Tesla, while his range is reduced in cold weather, realistically, it's only 10-20 miles off the top of his range in the cold months. It's nothing as drastic as you say at "50%!!!!"
Fearmongering about electric is ignorant.
EDIT: I suggest you check out some Bjorn Nyland videos on YouTube, he lives in Norway, and posts lots of videos about electric cars and the weather they have there. This one for instance seems to address some of your fears :
