Datamunger - my point is that the improvement in GDP/mile has been doing on steadily since the early 1990s (the trough was 1992), even though oil prices were modest for the first ten years or so of that period. So it's pretty hard to argue the recent cotuintanion of that trend is oil price driven (especially given there's no evidence of an oil price effect in the 1970s).
