These problems are (imo) vastly overblown for the way most people drive. The only time the cold temperature reduced range / reduced charge speed are relevant is for long road trips where you’re driving > ~200mi at once. Otherwise, you just charge up at home overnight and easily recoup any normal driving range you used during the day, regardless of the temperature.
Norwegians have apparently figured this out. Despite being pretty damn cold, they’re buying EV’s almost exclusively now (97%).
Norway is not damn cold. It sits next to a warm, Gulf-stream ocean. Rarely gets much (<-10 Celsius) below freezing.
Finland, that's another thing.
