Only when someone shouted for them to move. But most of the
time, they just stop at the rear's face-to-face seats.
Not sure about the gearbox, but the bus seems to be "tired",
like a human moving with a heavy backpack.
You and the group of kids are the same. I have seen many of these
groups of bus kids making a nuisance in the bus. Either making so
much noise, taking up the spaces, eating and drinking so openly,
cause the bus uncle scolds them, passengers glaring at them, etc,
yet have the cheek to lecture people online.
Sometimes I can feel for those people who are irked by their
actions in the bus~
