Ricing vehicles (mostly cars) used to be a big thing, enough so that when "rice" first started being used it was a common term to even people not into the hobby. I think it's a... not skeumorphism, but whatever the tern is for anachronisms like "files" and "folders." Metaphors carried over from the before-times.

Unlike "disks" which is a term that used to refer to a specific thing that's largely been replaced by rectangular solid state devices. I feel as if there are, or should be, terms for these language elements.
