The law in California is on a 2 lane road, if you have 5 vehicle1s behind you, you must use the next "turnout" and pullover and let them go by. I have found that if you do this, most people will thank you by tooting their horn and waving. If they give you a one finger salute, they are just showing their IQ or age. just ignore them and continue on your way. when going up a hill on 4 or more lanes, just stay in line in the slow lane unless you know you can pass in a short distance. In other words don't get out in the passing lane and stay right next to the vehicle you are trying to pass because you don't have the power to pass, that will really PO everyone.
