Most of the US Midwest sees -20 C for at least a brief period each winter. Having reduced functionality at those temps would be pretty inconvenient for the many car dependent people that live in the region.
Charging being a couple minutes slower a few weeks a year is a minor convenience. If you have a house with a garage, like many people in the US Midwest, I doubt it even poses a problem even on the worst days. It's more in the winter-long -35C areas that (purpose-built) combustion engines have obvious benefits.
Cold climates suffer more from cold batteries having reduced range, but with modern battery ranges the problem isn't even that extreme anymore.
China and India both have EVs much cheaper than we get in the EU. Like, "<€10k new" cheap.
What I do wonder about is how much of Africa can get EVs; I've only been once, to Nairobi over a decade ago, so take it with a pinch of anecdote-flavoured salt when I say that what I saw there was a lot of 20-30 year old vehicles.
Realistically you are looking at trimming 20->30% of the range. If you drive 20 miles a day but have a total range of 200 miles, then it's really not inconvenient. It only becomes inconvenient if you need to travel long distances.
