The Cybertruck's steel is made in "coils that resemble giant rolls of toilet paper,"

All steel is shipped from the steel mill in coils just like that.

Other manufacturers of all manner of stainless products seem to have figured out a solution to the problem.

Two design choices together probably make the problem multiplicatively worse:

Flat panels are not anywhere as stiff as curved panels.
Mechanical parameters of the stainless alloy they're using (eg it might retain the coiled shape more than some other plain steel alloys).

I can't get over the flatness... those panels surely rattle too? Or do they void-fill the doors and body with something?

Don't older cars have mostly flat panels? So it should be possible, right?

How old?

Early 1900's: Yes. Metal panels had the same problem, timber panels did not (their thickness stops them from flapping).

Late 1900's: I don't think anyone used flat? There were definitely designs intended to look flat (esp 80's and early 90's), but there were still subtle curves to those panels to bias them and stop them flapping, as far as I recall.

Happy to be proven wrong :)

Okay, that explains it. Thanks!
