As a former Tesla Model 3 owner (it got totaled from getting rear-ended) and now own a Ford Mach-E as well as a Toyota RAV-4 Prime (plugin hybrid), yeah I totally agree. Cold weather is the worst for EV cars. You have to spend so much energy keeping the batteries warm on top of spending more energy to keep the cabin comfortable.

Heck even the RAV-4 is a problem because it uses a heat pump instead of resistance heating, which means it can't heat the cabin in full EV mode when the temp is < 20F, so I force it into gas mode to stay warm on those days.

Not sure how you fix this problem, other than just continuing to improve energy density in batteries to where you don't think about it anymore.
