Bean bags that are small and used in tossing games are usually a cloth bag with small pellets of plastic inside. A bean bag chair usually has a leather outside that is filled with tiny plastic pellets. Bean bags can also be made using rice for the pellets.
It is probably because of the rear air suspension... Lincolns have an "air" suspension which helps to give it a plush riding feel. There are bags near the wheels of each rear tire that are filled with air upon vehicle start up (or very shortly thereafter). These bags are filled with air has the vehicle is on, inflating if there is a drop in pressure. When the vehicle turns off, these bags are deflated thus lowering the rear end of the car.
