Shut the country down for one hour

Designated date and time, everyone stops there autos and block traffic on every road in the country. A shot over the bow if you will. A protest that the next time will be 2 hours. What would zero fuel sales for one hour do. How do you let the true enemies of America know we have had all we are going to take. Could the whole country stay home and not spend a dime for even one day?? At least it's an idea.
