First, 'Stainless' is not a single item and in fact a wide variety of alloys with sliiiightly differing compositions which confer more or less corrosion resistance in favor of other mechanical attributes of the finished product. I have read (but must admit I do not know the accuracy of the claim) that Tesla went with a harder yet less corrosion resistant form of stainless for the cybertruck.
Second, while they see regular use the profiles of wear for e.g. cookware are very different than that of a car's body. For one, you likely thoroughly clean your cookware relatively soon after using it. How often is the car thoroughly washed down? The outside chemicals, road de-icer, quantity of UV or other environmental effects that differ between the daily life of your average chef's knife and a given cybertruck also very much play into it.
- handsclean 3y agoThe comparison point is a kitchen sink, not a chef’s knife, and Cybertrucks rust after only a few days in the rain, and somewhere it doesn’t snow. Some stainless steels don’t even rust in salt water. They could have chosen a stainless steel that wouldn’t rust, they just didn’t. It could be a mechanical compromise, but the shell isn’t pushing mechanical requirements. I think it’s much more likely cost cutting, supplier problems, aesthetics, ineptitude, or a sleazy attempt to sell more wraps. Whatever it is, it was avoidable.

The Cyberpuck does not always get the luxury of air drying even. It is consistently exposed to acid rain and sometimes to high concetrations of road salt and sand eating the smooth surface making it vulnerable.
