Yes.
The pop trucks, again, operate within city centres. That's why you see side guards on those. Those side guards, I can guarantee you, are not creating a fuel economy benefit in that particular case, because they're not travelling at highway speeds. They're not highway vehicles. That's why they have side guards; it's because they tend to operate more in urban areas.
In terms of what's happening right now both in Canada and the United States, the U.S. announced last May that it was going to introduce regulations for fuel economy standards/GHG emission reductions for new heavy trucks. Canada, at the same time, said that it was going to mirror those regulations, and that is in the process right now.
I think we obviously want to be as compatible as we can, but I'm not sure that just adopting the U.S. regulation is necessarily the way to go. In fact, we've proposed to Environment Canada some areas where we have to make sure, because Canada has a different weights and dimensions regime, that the base vehicles that they use for measurement don't put the Canadian industry behind the eight ball.
Also, there were some areas in which we felt we can and should go further in Canada, and those things are being worked out right now. I don't know whether that will come to pass or not. The regulation is somewhat different from the smog regulation. The smog regulation said that by such-and-such a year, the truck manufacturers in North America will eliminate the emissions of particulate matter and NOx, two major precursors to smog. They basically said, “We don't care how you do it, but you're going to do it.”
In this case, it's not really as prescriptive as that. What the regulations, as we understand it, will say to manufacturers is that a portion of their sales have to obtain a certain reduction in greenhouse gas emissions. They will either be given a credit, if there's a market for it, or perhaps there will be some penalties or lack of credit if they don't get there.
There's nothing that compels the customer to buy what we would call a GHG-compliant truck. If somebody walks in and wants to buy the same big old thing—I won't use the brand name, because they take heat for it, but they also produce good trucks—with way too much horsepower and all the bells and whistles on it, they're going to sell them that truck. It's going to take a long time for this regulation to have the kind of effect on GHG that they think it will have, but it is a step in the right direction. What we've been arguing is that it should be supplemented by a program of complementary measures that would allow us to retrofit existing equipment and include trailers. The EPA has said that they are considering regulating GHG from trailers because it's all part of the aerodynamic drag, and you have to look at the whole vehicle. They're considering it by maybe 2018.
