The U.S. is dependent on cars, and therefore dependent on oil. This has forced it to invade other countries and has drained its economy.
Because the system of cars is so complex and extensive, the U.S. cannot change quickly. Every day oil is more expensive. This will cause the U.S. to take more desperate actions to save its economy.
