Just a comically bad fit on the rear taillights of the Cybertruck, so extreme is the mismatch that it almost looks like it was done on purpose, except that it obviously wasn't. Tolerances are measured in centimeters here, not millimeters (let alone microns). Note also the thin, isolated side panel on the right, looking like it wants to cut you. Vehicles aren't supposed to look like that!
