Is it, though? Honestly, how many routes would even use them, and to what degree? The 3 sees respectable ridership between White Plains and 242nd Street, yet it tends to use the same buses as most routes despite its long express segment. Routes 1X, 43, and 62 are express variants of routes 1C, 40, and 60, so they'd be better off using the same buses as their local counterparts. How long routes 17, 28 (BxM4C), and 77 will last is a huge question mark, and the same can be said for route 10. Regular coach buses are far more likely to run into clearance issues, which means they can really only run on a single route (28), while buses with a single doorway and/or a high floor increase dwell times at bus stops.
