Apparently your driving skills have impressed your mafia boss, because he orders you to start working as a car thief! Steal the cars indicated with a green arrow. You'll sometimes have to move some other cars first, otherwise you can't reach the exit without colliding with them. That's something you should avoid because this might activate a car alarm, and cause you penalties. Keep an eye on the clock! A good car thief works quickly and unnoticed!
Use WASD or the arrow keys to control your car. Press X or Enter to get into or out of the car. Press Shift to speed up. Press the spacebar to drift. You can move the thief or the car with your mouse.
