Easy Points
Start a Derby Race but refrain from bashing into cars; this may be the way you are supposed to play, but there is a trick to winning this game mode and earning easy points. Drive around the outside, avoiding the action until your Connection Time is running low. Hit a car, then return to the outside; repeat this process whenever your Connection Time is on the verge of running out. Go in for the kill when two cars remain by smashing into these cars with your prime condition vehicle. You earn 2,000 points for winning a derby you were barely involved in.
Cheat Codes
Choose "Extras" in the main menu and then select "Enter Code." Input the cheat code "KALJAKOPPA" to unlock the Rocket Car. Enter "WOTKINS" and the Flatmobile will be available for selection. The "GIEVCARPLZ" password unlocks the School Bus and ELPUEBLO gets the Truck. Use "RUTTO" for the Pimpster and "BIGTRUCK" for the Mob Car.
