That's a very old trick. There was a rash of thefts when I was younger where the thieves would wedge a thick stick or some other object between the ground and the axle of the car. When the driver pulled out they would hear a loud noise and sometimes, depending on the object, feel the car lurch. They would stop and get out to inspect it and the thief jumped in and took off. This was even more effective than the scam in the video because the thief never had to stop to take off the noisy object being dragged behind the car. It also drew no attention to them while they drove off. I don't know about you, but I'd take a second glance at some dude dragging empty gallon jugs behind his car. Might arouse suspicion.
