I've owned a Tesla through 4 winters - including temperatures in the negative teens.

Yes, you can go out to your car and have 50% of the battery reserved.

By the time you've used 10-20% of the battery, it is now fully unlocked because it has warmed up.

Maybe there are inexperienced EV users who don't realize their batteries warm up by driving making complaints (this is the first time any F150e owner has ever had their truck in winter) but they will soon learn that it's a non-issue.

You can't possibly consume 30-40% of your car's battery and NOT warm the battery up. Your motors generate too much heat, it has to go somewhere or the motor will melt into slag.
