Three plug-ugly cars which never got beyond the prototype stage. The first one, a 1948 Davis Divan, looks like a cross between a bedroom slipper and a steam iron. It might also pass as a Bob Clampett cartoon character. Supposedly it could hold four people across, or two people from 2017 in a tight pinch. I saw someone on YouTube (Jay Leno - see video below - I found it finally) try to drive a reconstruction, and he complained it kept tipping over.
The second one is oh, oh, my God, just horrible to contemplate, as lumpy as the Elephant Man, an airstream trailer with a horrible disease. I guess it sort of looks like someone's idea of a futuristic rocket, but it somehow does not get off the ground.
The third one commits the sin of being merely dull. It's a kind of '40s race-car-type-thing, but why the wheels are encased like that puzzles me. Wouldn't that make them more susceptible to damage?
There were hundreds of "futuristic" designs like these, and in many cases the designers found backers, pocketed the money, then got out of town fast.
