[Syndrome]

Why is it some drivers believe they have a personal space on the roads which cannot be encroached? I was driving for a couple of km behind another car. At one point they indicated left and pulled to the side. I believed they were either parking on the side of the road or entering a driveway. However when I passed them they immediately pulled out behind me and continued in the same direction as before. WTF! About 100 meters later I repeated their maneuver and ended up behind them. We stayed that way until we reached a roundabout and went our separate ways.
