Vehicles

All cars have nitros

Cars float away *
Bump into another vehicle and it will rise into the air and float away. It will float in whichever direction you hit it from, and the angle at which it floats depends on the force you hit it at.

Traffic is country vehicles *
All traffic is replaced with vehicles normally found in the countryside.

Traffic is country vehicles (minus hillbilly gear)
This is the same as the other 'traffic is country vehicles' cheat, although you don't recieve the hillbilly gear.

Traffic is crap cars

Invisible Cars
All vehicles invisible except motorbikes (only the wheels are invisible).

Improved Handling (Hit R3 to jump)

Faster Cars

Aggressive Traffic

Reduced Traffic *
No peds and only an occasional car on the street. Parked cars still spawn. Great for cruising. Still enough cars that you're not totally stranded if you wreck your ride.

Destroy all vehicles

Taxis have nitrous *
Cannot be turned off. When code is typed in a second time, the "cheat activated" text is again displayed.

Fast/Rare cars appear regularly *

Black Traffic

Pink Traffic

Cars Fly *
But not like they did in Vice City. The controls are more accurate, and the whole process is just like flying a normal plane.
