The driver left the steering wheel and went to sleep.

The driver looked tired and sleepy, covering his mouth with one hand as he yawned, his gaze out the window revealing the car traveling at a fairly high speed on the highway. The protagonist then lifted his suitcase and propped it against the gas pedal, straightened the steering wheel, and climbed into the back seat to sleep. The camera then panned back to the window where the scenery whizzed by, focusing on the empty steering wheel and the suitcase near the gas pedal. But when the camera panned back to the road ahead, the truth was revealed: the car was actually being towed away by a tow truck, not driving itself.
