don't blow through red lights and stop signs
don't drive the wrong way on one way streets

when do you use the sidewalk? only when absolutely necessary and not at speed - example: tough intersection and turn where you might get squeezed and piss off drivers

Do you split cars at a stop light and go to the front, or do you hang in the back where you happen to fall? - this is called filtering and is usually OK. there are some situations where it should be avoided - too many options to cover them all here
