From the other thread at PP.

That's a Dyson... Australian bus. They had 2 engines, in front and rear.

The Santa Fe RailRoad (AT&SF) built buses like that during WW2, out of plywood.
With a powered front bogey.

And the main body was 2 levels

VictoryLiner...

I've included it in this thread because even a long skinny brick (train-like fineness ratio) is better than a short body (most of the time).

Probably airbrushed. It was the style at the time.

The Cybertruck turns out to have those hard edges because its's made of the same stainless steel as the Star Ship. Stainless steel wears out the forms used to stamp the pieces. No compound curves for you!

I like the Landliner a lot. Maybe there's one in a barn somewhere waiting to be found.

edit:
I've been thinking about it. Consider the way the Star Ship has evolved before it has even flown, I suspect that people will like it even better as the fabrication issues are evolved.

Two of the 1960 Thunderbirds were produced, with T304 stainless steel bodies and both traveled around the country to be shown at various automotive events. Each of the Thunderbirds, like the earlier ’36 coupes, logged more than 100,000 miles. Three of the 1967 Lincoln convertibles were produced and Allegheny Ludlum still owns two of them.

(Ford rewarded their top sales people with use for one year)

The temper of the Tesla/SpaceX alloy is no doubt stiffer.

Satecmo Eolia 1954
André George Claude was an engineer, who decided to devote his time in designing and building a high performance French car.
The Berlinetta style body was designed by Eiffel and was made out of magnesium with Claudes company Satecmo, building the car and mounting the 4-cyl 850cc engine from a Renault 4CV centrally in the rear of the car, mated to a 5-speed transmission of his own design. Access to the engine compartment was provided by opening rear quarter panels.
Interestingly, the steering wheel was located on the right hand side as this was Claude's preferred option for driving. The engine in 1960 was later to be replaced by a tuned engine from a Renault Dauphine Gordini.
Claude's innovative design was offered to Renault, but there was no interest in producing it and so the car exists as a one-off special.

I am quite curious about the specs on this alloy, and the inner construction to support it. It may work like a drum-head for that demonstration.
However, I do know that hardening and tempering never affect stiffness, just how far something will distort before being permanently bent or broken. Stiffness is set by the forces between the atoms, while hardening just arranges the mix on a fine scale. Alloying elements are generally too low a percentage to have much effect on stiffness, and those for stainless properties are selected for their surface oxidation qualities, often reducing stiffness a couple of points, while banishing the use of carbon for cheap strength. Cheap stainless steel is often half the strength of common aircraft aluminum, but still 3 X the stiffness.

Other approaches to corrosion-free construction are aluminum or composites, either of which could be ribbed as on the Citroen 2CV for lightness. I also notice that minor dents have no affect on the service life of pickups. The DeLorean didn't rust, but it took stains from hand contact and much else.

That's quite the post It's hard to choose between the three!

Thanks. Since I posted that I watched this:

Known but unexploited until 1913. From cutlery to cladding the Chrysler building (Delorean-like) to structural in the St.Louis arch (Cybertruck-like).

As to the fabrication issues, DDG/?q=3d+print+stainless+steel
