It's [stainless steel] also stiff, which makes it potentially more lethal to anybody unlucky enough to be struck by a vehicle built with the stuff.
Of course they picked a more deadly option.
The documentation says: “To prevent damage to the exterior, immediately remove corrosive substances (such as grease, oil, bird droppings, tree resin, dead insects, tar spots, road salt, industrial fallout, etc.). Do not wait until Cybertruck is due for a complete wash. If necessary use denatured alcohol to remove tar spots and stubborn grease stains, then immediately wash the area with water and a mild, non-detergent soap to remove the alcohol.”
Loooool. That's pathetic. A truck you have to baby or it stains and discolors.
