The Aptera, eh? I hadn't heard of it before, but I looked at their website and they have a "Reserve Now" button combined with a FAQ which says "We are currently in the process of setting up our production facility". I think that moves it out of the "already exists" category and into the "vaporware until proven otherwise" category.

Actually you can right now get electric cars from Zap or GEM for less than $20K which are suitable for commuting provided your commute is very short and very slow. I'd be tempted to get one myself if I actually had a garage. But we're nowhere near anything that could be called a replacement for a real car, rather than a supplement to one.
