Today's internal combustion engine works well in the BRT. Any propulsion solution you're going to take will benefit from the BRT.
So going at a faster pace with fewer stops—stop and go—and travelling with a lot of people.... Of course today if you want to have a high rate of transportation, the combustion engine is the only solution, but even an electric bus would benefit from that. I think both our companies are making a big stride in having a 40-foot electric bus. But thinking about the high-capacity electric bus, today we're not there because of the capacity.
