I like to imagine building something like the Thyssenkrupp Blue.Cruiser some day, but with all-wheel drive hub motors and about 250 horsepower on tap with the car well under 1,800 lbs and the whole roof and hood covered in solar panels... It takes cues from the Volhart-Sagitta V2, the Bosley GT MkI, and Ferdiand Porsche's Type 64 prototype. It's a practical and functional shape for a sports car that just so happens to be ridiculously efficient. I don't know what max top speed it would have stability at, but its acceleration would be ridiculous and when you didn't need it, its overall load at speed would give a VW 1-litre competition, and you could still theoretically reach double the legal speed limit in most U.S. states on roughly half the horsepower of a Geo Metro...
I'd probably never need a charging station with something like that...
