At least in San Francisco a bus is king of the road. They will run a red light at normal speed and just beep beep to tell everyone that this is happening. An abrupt stop isn't possible because people are standing inside and might get hurt.

Same reason why a bus will not suddenly slow down to let you into their lane unless lives are at stake. Which at sub 30mph speeds they're not.

Best to treat a city bus like it's a train.

You can think of being a bus driver in city traffic as a constant trolley problem. As a professional driver, do you risk injuring 50 people inside the bus or 1 idiot on the road?
