Can't comment on these cars yet, but I'd say Tesla's 120v60hz is some firmware that's worn pretty well, and the math underlying its 3-phase generation was done in his head, so the story goes. I'd say the stuff he 'supposedly' invented has been pretty well justified by the things he actually accomplished.

-First Radio controlled boat, central park, 190?
-Fluorescent Lighting

etc, etc.

"Father of Vaporware" was so outlandish to me that I held back from posting. I don't own any of the many books written about Tesla and it's been decades since I've done the kind of reading required to addequately refute the label.

I would be surprised if a large portion of this particular board's readership was well informed of Tesla's contributions. Most here seem to have a high degree of formal education in the sciences, which I certainly don't. That can create a tunnel vision.

Your points are just the obvious contributions of his career. The non-obvious is what was taken by the Yugoslav authorities after the FBI took what they wanted.
