Gimme a brake

I'm convinced that there are some bus drivers who have never actually ridden a bus before. Particularly those who like to slam on their brakes at every bus stop and red light. Have you never driven this route before? Did the bus stop sneak up on you? Or have you just never heard of gradual deceleration? Maybe that's not something they teach in Bus Driving 101. I guess it's not that important; it's not like any of us are trying to keep our balance and not fall over on these things, right?
