I think it just might be true.
I could see a long list of classic levels, and then an option to design your own level in a simple way, not unlike the way that Rollercoaster creator games/programs work - you have a set of pieces that you can use, designed so that they can be fit together neatly. The exact choice of layout might influence whether you only race on one side, or on both sides.
Think of the Mario Mobius track - I could see that being a user-created track, since it's got a fairly "generic" appearance, with Peach's castle being the only real "landmark" on it.
