A bomb was found in one of the government establishments. You knew that the bomb squad couldn't make it on time, so you take action and put the bomb in your car. You drive the car to the bomb squad, where it would be disarmed. Time is ticking each passing seconds.
The car moves by its own, all you need to do is to make sure that the car won't crash. Pick up some alarm clock along the way for extra time. Do some stunts while up in the air for added time. A perfect landing also gives you some more time.
