The tag for rainbow road is usually supposed to be reserved for the specific track from Mario Kart, implied by its tag description. However, I've seen some people use it as a general tag for any rainbow-colored road in a non-Mario context in post #8915773 and post #8926855 for examples. I know these are the only posts that are tagged like that and I was going to simply just remove the tag off of them but then it had me thinking if the tag should really only be for Mario Kart or for any road that is rainbow-colored in general, since the concept of a "rainbow road" sounds very general in and of itself.
