Electric resistance heating, the only source of heat in an electric car, is the most inefficient use of energy there is.
Electric cars are a solution in search of a problem, and introduce 100s of problems of their own.
well not likely a 100% options, does not the electric motor it’s self create heat when in operation? I think I recall Toyota using a cooling system just for the electric motor. I would think this waste heat combined with electric heat would help with distance.
