I think you could make a cracking Carmageddon style game with this engine - currently it does look a little boring to play, feels like it needs some more interesting objectives other than driving to the yellow markers (although I see that you say this is just a subgame, so maybe you have a definite purpose in the main game?)
Swap to a city-style landscape with a looped course through it, add some nicely splattable peds and have maybe 20 or 30 racers...
