Its an interesting idea, but not one that fits a WO style game: how can the feature enhance the project?

WO tracks are generally too simple to justify a map- perhaps on a rally game but here its really wasted. You could argue it shows you where your opponents are, however, you can do this via times on a leaderboard (as in online matches) and split times. The Wipeout ethos was always keeping the experience as streamlined and functional as possible and for me your idea goes against this.
