So you can't give us a dealer's name?  Can't cite an driving test
article?  Not a surprise.

Jet cars are reality, the first was in 1950, and one raced, but you can't
buy one of those either.

 

I've helped build some pretty exotic lab prototype vehicles that need a
full-time mechanic to keep them running, the same as race cars and fighter
planes.

They were "real" and functioned as intended but were nowhere near practical
or ready to sell to the public, which is the true goal that developmental
prototypes should lead to. Otherwise they are just engineers playing at
their hobby and trying to sucker you into paying for it, the way the
entertainment industry does.

Even GM can build a failure, as with the Wankel engine. The problems that
kill them are never mentioned in the press releases. Research the
thermodynamic efficiency of a steam locomotive, for a good example.

A high-maintenance homemade example at work:

Jet turbines in cars were ready for production if need be.  One raced the
LeMans 24 hrs. They did not need a mechanic standing next it to make it go.
They just were not fuel efficient enough and the engine characteristics did
not lend it to road car usage.

But they worked reliably well.


GMs may have been a failure but the Wankel overall is not. Many milliosn
have been made - it is still made today and used in a variety of roles.
Audi are considering it as a hybrid range extender only turning a genny.
Very small and efficient when running at it "sweet spot".
