Chicago has half the population of the entire country of Norway, in a space 1/50th of the size. It also has extremes on both ends of the temperature spectrum.

Chicago has half the population of the entire country of Norway, in a space 1/50th of the size. It also has extremes on both ends of the temperature spectrum. It's hardly a fair comparison. I spent 20 years in Chicago, the people there are used to and ready for winter extremes. Teslas have their fair share of issues, but the real problem in Chicago is relatively few people have access to home charging compared to the number that own EV's. It's one reason Teslas are so popular, as every other EV is a pain to charge exclusively with public charging. Reduce their range with cold, increase their charge time with cold, increase the rate of usage with cold (as it's too cold to use bikes and walk for many people) and yes - you're going to run into supply shortages during extremes. To prevent that, you'd need oversupply in the bulk of the year, and the footprint of Chicago and real-estate cost simply doesn't support that.
