Wrong on all counts
No, zackers, as usual, you go well out of your way to miss the point. "Poor science" is making your argument without supplying any data, and missing important details, like the spelling of my name. You consistently manage to do both.
Indeed, you reinforced my argument: high prices helped to kill demand, which is a fundamental aspect of the recession. It's completely backwards to assert that "if the global economy ever gets out of its funk...demand [will] go down even further." Growing economies consume more oil, not less.
Nor did my argument make any claim whatsoever about the efficacy of fuel economy standards going forward - my analysis was strictly about the efficiency of new vehicles in the recent past.
If you want to argue that our oil demand has declined for reasons other than the recession, or that vehicle efficiency has contributed more to that decline than I calculate, then you should do what I did: Dig up the data, and show your numbers and their sources. Anything less is just blabbering.
