What we find on the bus side today is that, when you talk about bringing the whole bus over, the barriers to entry are certainly significant in the United States. That would probably prohibit somebody bringing their bus over, simply because of Buy America alone, unless they set up manufacturing facilities. It may be less so in Canada, but the rules and regulations in terms of the other dimensions and such on a bus are still significant enough between Europe and Canada. For that matter, it's still a challenge, plus the freight costs. It's still pretty hard to be competitive.
I kind of agree with the comments on the propulsion side. It's a problem that there's one guy. One person supplies all transit buses today and everyone else is evacuated. A second, Navistar, is coming on, but today it's just Cummins. So the ability to have different propulsion options, as long as we weren't testing and having to certify everything for emissions, I think wouldn't be a problem.
