Okay.
Regarding price signals, let's talk automotive for a second. Thirty-five miles per gallon is the standard for the new U.S. reform CAFE, and that has to be achieved in two vehicle product cycles. If we harmonized with that type of regulation, for example, it would send a very definite price signal to the auto industry, one I don't have a specific number for. I don't know whether that's something you could model. That will affect transportation choices for Canadians: vehicle choice, materials, technologies, manufacturing locations, and changes to collective bargaining agreements potentially. There are a lot.
What I'm getting at, in terms of economic modelling, is that if you want to capture costs, there are a lot of costs that could be captured in here. Are some of those things addressed? Those are additional corollary things that we have to consider.
