Very briefly, as far as the U.S. is concerned, we're very much a follower because of harmonization and because they're the big elephant to the south. There are regulations, but typically we are staying pretty much in lockstep. The current regulatory process to adopt their regulations is actually not bad. It's fairly streamlined; it allows for it to happen fairly quickly.
As far as other technologies advancing, yes, in Europe especially it does seem to be quite a slow process, but it's bringing it into our culture, our environment, that is a bit of a challenge. There's an awful lot that's actually being worked on in Transport Canada, and hopefully we will see things move along. I don't have a list; it's something I can think about. But I can't, off the top of my head, suggest anything.
