I suggest changing the "100% Mirror" category to "100% Reverse" to better reflect the in-game menu as well as the actual tracks. You actually race the track in reverse! 😲

Side anecdote, "mirror" modes in racing games are more prominent perhaps due to course layouts being effectively unidirectional, due to gameplay, geometry, or AI. It's easier to mirror the geometry rather than "teach" the AI how to drive another "track".
