On the technology, I'm not an expert, but I did talk to this group I mentioned to you earlier, and they have done some testing in urban canyon environments, and sometimes GPS bounces off the building walls. So there are some difficulties, but from my understanding they're getting to the point where it's quite accurate. I think, really, where we have to focus road pricing—and this is probably a 10-year plan—should be in the urban areas. It's not just Toronto's issue, it's almost every urban area.
