Perhaps I can add something. STM is a huge bus operator, so we have a responsibility to the smaller ones to test new things. I have many engineers and technicians working for me. If you take the Trois-Rivières society, they have no engineers. So they use AVT, Serge's group, to get information from us and it's really a matter of coordination among everybody.
Huge bus companies like those in Montreal and probably in Toronto and Vancouver have this responsibility to test these things with our knowledge, with our engineers, with our mechanics, with our technicians. For example, we don't do that too much with the metro, because on the metro side, we're not a big metro, so we leave those experimentations to the Paris metro, to the New York metro. Because even if it's very big, the metro in Montreal in comparison to other metros is small.
So these big metros have a responsibility to us to test all those new technologies. But we do that on the bus side, because I think we're the fourth largest bus fleet in North America, in Montreal.
