if your trying to steal a car for Brucie or Stevie but theres a copper around and you dont want to risk a wanted level go up to any car with a person inside and run up to the door and press B to push it. this counts as damage to the car and the person in the car should get out and try to beat you up. run and stand a short distance away from the cop so that the driver has enough time to run let the driver hit you and the cop will come to arrest him. the driver should run away, thus leading the cop away to leave you alone with the car. you can also use this method to assasinate people or any other reason you have.
