I think I smell the same problem we had in the mid seventies. The threat of prices going up will cause a gas shortage. Back in the 90's I worked on the Y2K thing and went to several high-powered meetings. One of the guys there was from the petroleum industry and he explained it this way. Let's say there are 100 millions cars in the US. (leave out trucks, tractors, public trans etc) For the sake of this exercise they all have a 20 gallon tank. And we can assume that they average out to half full. (At any given time some will be full, some 3/4, some 1/4 etc) If everybody decides to beat the price increase and fills up that would be about a billion gallons of gas out of the system. That ain't exactly scientific but you can see where it will really screw up the delivery system. Plus the stations can make a lot of money and take a few days off while the system catches up.
