The US peak didn't cause price changes because cheap oil could be imported, until the 73 shock (when global supply got very tight, and then OPEC restricted it further).  Then it did cause high prices.  The global peak cannot be covered with imports, so it should be very clear in prices.  You don't think it's going to take higher prices to make oil usage decline at 3% or 5% or 8% a year, or whatever oil depletion ends up being, than to have it grow at several percent a year?

My opinion is that the peak oil case appears to be very compelling, and that as more and more people get past their prejudices and take a hard look at the evidence, they will be convinced of it too, and the price of oil will go up and up.  It's only just starting to get mainstream exposure now, Once people believe that oil is going to be more and more scarce in the future, they will want to buy it now.
