Tesla exaggerated EV range so much that drivers thought cars were broken

Battery heating makes an enormous difference. I live in Ontario and generally average about -15 to -20 during the winter. Bought a Hyundai Kona EV in 2020 and it's been great. Actual range in summer is about 450km cuz I drive like an old man, and it drops to about 350km with my high traction winter tires, battery heating, and cabin heating.
The Kona also won for the best actual range during winter a few years ago
