@hissingmeerkat @pageflight Expanding on "Drivers spending time accepting fares instead of driving. " and physical layout:
It’s better for bus timing and passenger efficiency too. You can now board and disembark from the back or front of the bus because it just doesn’t matter any more. You aren’t required to slowly board up front to pay the driver. An in->out flow *may* be nicer, but dropping the requirement will still help and speed things up.
