I follow a number of practices that I think make me an exceptional driver.
I don’t tailgate.
I generally drive in the right lane on highways and, related to this, I tend to drive the speed of the surrounding traffic rather than slavishly driving posted speed limits.
My policy for right turn on red, for changing lanes, for left hand turns where I yield: I do not want to cause other drivers to have to change speed.
I reserve use of my horn for serious situations, which is to say, I rarely use it.
