If you are going near the speed limit in many parts of the country on a two lane road you WILL soon be holding up cars. Especially when the hours are around going to work and leaving work. I'll come out of Tupelo heading north on the Trace around 3 pm and set my speed 5 mph ABOVE the speed limit (checked by GPS) and will routinely have a line of 5 to 10 cars back up. Tough, I'm speeding. And I applaud it when some jerk passes me and a few miles down the road I catch up to him on the side of the road talking to the police.
