questions about the drift leader boards.

so i noticed that there are leader boards with best of lap scores for drift races after completing a run in free play. sweet now how can i browse through the various tracks and view the leader boards without going to each track and completing a run? sure as H E double L cant check out the leaderboards after a multiplayer drift loby run. before you have time to react to the (press x for leader boards) button the screen changes. so whats the deal? and after putting in half a day trying to one up my buds score on maple valley full reverse it does not record my score! any ideas on whats up with that? And before i get any sheet bout being a (points drifter) just keep in mind this is only to bust a few friends balls for bragging rights. im all about banging doors to bruh.
