I think after all this falls under the super-category Velomobile [1] - there are plenty of other examples for two-seater, electric assisted Velomobiles.
Also, Velomobiles are way more popular. My unkle (used to?) drives one every day to work, in every weather, 40+ km one way (without electric assist, at least a few years ago). And no, he was never cold, he rather had problems with ventilation ;)
