In my experience with Asian transit systems, a lot of them expressed to me that an urban transit system, especially those using buses, is a closed system. When it is a closed system, why are we concerned about the safety regulations that we have imposed upon ourselves in Canada?
For example, Montreal itself is a closed system. I don't expect you ever to export your buses, unless, when they're finished their service life, you send them down to South America. But before that, within the seven-year economic life that you mentioned, because it is a closed system, why, if we buy enough of them, wouldn't the suppliers around the world—the Fiats, the Volvos, and all of those—not meet our requirements for the windows, for example? As far as the propulsion system is concerned, it's not a problem. Most of the stuff is just very minor cosmetic changes to the bus.
