There is a limit to how expensive oil will get, thus many of these expectations I disagree with. Right now what people think of as "oil" is only a particular class of oil- light sweet crude. This is easy oil and is cheap to produce. This may be running out. I don't think the hubbard peak is actually correct, but for purposes of discussion, lets assume it is. As the price of oil goes up, a lot of lower quality oil becomes economically viable. At $150 and a bit of time developing infrastructure at that price, and there is probably more economically viable heavy sour crude, oil shale, coal tar, oil sands, etc than there was ever light sweet crude on the planet. People will still drive at $6 a gallon gas, especially since by that point sodas will be $6 from vending machines due to inflation.
