The Cybertruck Is the Dumbest Thing I've Ever Seen: Elon Musk enters his Caligula era.

The Cybertruck—or CYBPRFRVKK, according to its " target="_blank">illegible branding image, which looks like a white suburban teenager’s first hesitant attempt at tagging the local Red Robin—is due to be released today. It’s the first new Tesla design since 2018, and the company has spent over four years and billions retooling its factories to make it. It’s anyone’s guess how much of a success or failure the truck will be, though the fact that at time of writing there is, incredibly, still no official information about price or battery capacity doesn’t bode well. But we can conclude that the Cybertruck is just possibly the dumbest vehicle ever produced. Here’s why.
Let’s start with the Cybertruck’s body panels, which are made of stainless steel. That is a nightmare for several reasons. First, it is quite a bit harder than ordinary steel, making it difficult to shape and machine. When Ford experimented with stainless steel in the mid-20th century, they discovered that the metal would eventually break the dies they used to press their door panels. Tesla has had to cut the sheets with lasers and bend them into shape, which is undoubtedly more expensive.
Second, there is cost. The chromium and nickel alloys typically used to make steel stainless—that is, resistant to corrosion—are expensive, at about $11,700 and $18,300 per metric ton, respectively, as compared to about $800 for steel. And while stainless steel is resistant to dents, that also means that if it is dented it is difficult and costly to repair. Incidentally, automakers have long since developed techniques to combat rust that are roughly equivalent to stainless alloys, like galvanizing the steel (that is, applying a zinc coating) and improved paint. Indeed, stainless steel itself is not entirely rustproof, as anyone with a stainless knife or cutlery has likely discovered. Leave it under a damp surface like a cloth (or leaf, or bird poop) for too long, and it will start to corrode.
Third and perhaps most importantly, stainless steel is much stiffer than the ordinary stuff, which makes it dangerous. Since the 1950s at least, automakers have understood that stiffer cars are more dangerous to people inside and outside the car, because in a crash they deliver energy to other parties rather than absorbing it. In early crash test experiments with more heavily built cars, collisions often did only minor damage to the car but turned the test dummies into paste. Since then, cars have been designed with progressively more sophisticated crumple zones to absorb impact forces. Musk’s boasts of a Cybertruck “exoskeleton,” if true, are a recipe for gruesome carnage.

Good luck. 
Because, it's all I need. I've been looking for a year and a half and there are none to be found around here. Even in the lemon lots.
I guess their owners are driving them to pieces.
Shoe box had a baby.
There are at least a hundred grades of stainless.
Geez, cutlery is made out of about 20 different kinds, a lot of it 400 series, which is the biggest difference in price.
In our industry, we used mostly 316L, but a lot of Carpenter 20, monel, inconel, & 2205 got used too.
304 has lower structural integrity, but is cheaper for applications with very neutral pH, but high water. All that neutral water helps accelerate oxidation and most aqueous formulas are sensitive to color. Red is bad!
A shampoo plant, for instance, might use 304 with sanitary fittings, because of the benign formula and narrow, modest temperature ranges.
But, a chemical plant wants the added structural strength because of the wide range & possibly extreme temperatures.
I guess I can see the use in spacecraft as it's nonmagnetic. Austenitic stainless steels are almost completely nonmagnetic. That might be useful is the ionosphere where all those charged particles reside. Just a guess.
I don't know why they would use that for mufflers, though. It tends toward embrittlement with high temperature & mufflers get pretty darned hot! I'd think anodized soft steel would be better.
Back in my R&D days, I developed a couple processes with pretty extreme conditions, metallurgically.
Did lots of coupon testing, so we could pick a material that would dissolve or fail. 300°C, pH zero, material finding an exit would be bad.
We actually had to go with tantalum clad for one application. Boy, was that pricey.

One should not get high and watch Blade Runner and Mad Max at the same time. That seems like a genuinely terrible idea. And I'm pretty sure that was the inspiration for... whatever the fuck this thing is.
