that's one reason crash traffic happens and stays for hours after the original reason for the traffic to happen in the first place is gone. I remember reading that one person applying their brakes too hard can have a knock on effect causing a traffic pattern to emerge for a long time after the initial braking ever occurred.

Yeah, I wish this was emphasized more in driving school. I wonder how much traffic could be reduced just by making people conscious of their traffic-causing behaviors. (for example, using your brakes to slow down when there is nothing in front of you and others behind you)
