Not a Tesla fan but this article is garbage. Basically all sheet metal comes on coils "that resemble toilet paper" including the metal that other manufacturers use.
The missing point is it's a property of stainless steel that it remembers being a coil and can unflatten itself weeks later if the manufacturer doesn't know how to work around that.
I've worked with stainless steel (specifically 304, 430 and 401) for 15 years and the steel shouldn't have a memory after being run through a de-coiling machine that is configured properly. Excessive heat in a focused area would definitely cause it to warp but this can usually be overcome by adding geometry to stiffen the parts. It seems like the team at Tesla is missing a step somewhere.
