He was kind of a smarty pants. It depends on traffic and the situation but I guess will just agree to disagree not knowing the area but where do you draw the line. Traffic here regularly travel 80-85 mph. I'm not going to drive 75 just to be in the flow. Almost all highways have a slow lane and a passing lane.The people traveling at these speeds are going to be mad if they have slow down even if it's 70. I don't think there are a lot of accidents because people come up on a 20 mph overtake but I'm sure some one can find some links. I guess it's a good thing I don't drive much
