DeaH:If gas sales go down by a significant amount, isn't that also a measure of the amount of driving being done? It's not perfect - people could be using more fuel-efficient vehicles. But, still, it's pretty good.
I almost agreed but then economic reality sank in. About 2/3rds of corporations pay no federal tax at all, as in zero
<link> . It is not reasonable to expect that a liquid commodity like gasoline or diesel can be efficiently measured/regulated by the government. (Nice job they did during prohibition regulating alcohol even without huge pipelines and tanker trucks for transport across state lines.) So while there are very big numbers tossed around about fuel sold/consumed they are certainly very far from accurate. If still in doubt consider the monumental vaguery surrounding the 'peak oil' debate. Either they have an accurate number or they don't. (They don't.)
It would be immensely amusing though to compare the numbers for the total miles driven and the total gallons sold for both the periods when gas was cheap and now. Many fewer miles are clearly driven now but not so many fewer gallons are reported sold now is the likely outcome assuming that the reported numbers have always been chronically low to avoid paying taxes. They could only go so much lower.
Ironically the only explanation left then is that vehicles suddenly have been getting many fewer MPG. The liberals will blame the conservatives who will blame them back again for the loss of MPG of the average American vehicle during the past year. (Some quacks will blame it all on Ethanol and 'watered down' gas so clouding the issue.)
Meanwhile the experts, the oil companies, will insist that offshore drilling is the only way to increase the loss in MPG of the average American vehicle to where it had been before the price of gas went up. To save face both the liberals and the conservatives will agree and offshore drilling will be adopted. Everyone wins.
