The game's “interface” consists of a steering wheel to control the direction of the vehicle, a brake and an accelerator pedal to brake and accelerate respectively. For quicker and more acute turns, you have to combine the brake and the steering wheel at the same time. As each car has got its own characteristics, you will have to improve your driving skills with each one of them. You also have to be careful with unnecessary collisions, as your car will get damaged with each impact and will reach a point where it will be unusable. At that stage, the car will have to be left at the garage to be repaired and you will not be able to use it in the next mission.
