F1 2000's "Mysterious Roads" Cheat

In EA's F1 2000 there is a apparent cheat called "Mysterious Roads" which is Enter on pause screen: Hold Triangle and press Down, Down, Circle, Circle, Up, Left. But I can't figure out what it actually does from testing the cheat at Albert Park and Monaco it may seem to extend the run off roads but it looks like thats how it is anyway. Does anyone have a clue what the @#$%& the cheat does?
