What is it that flags us that a person hasn't seen you and is about to run the stop sign, or that the person in front of you is getting ready to change lanes before they use their blinker?
Years and years of driving experience,and by no means am I bragging. Remember I have said this a few times I expect everyone in front of me to do something stupid and they have never let me down yet. I can tell when someone pulls up to an intersection if they are going to stop or not. Hey you think they are stupid around your SUV try a transport truck it just seems to make the average driver extra stupid,they have to get in front of us even if it means risking everyones lives to do it.
