The Road Safety Authority (RSA) uses the following video to show us Irish drivers how to drive around an Irish roundabout. It is clear, simple, and so easy for even the dumbest driver to follow - if you are in any doubt as to how to correctly drive around a roundabout, this video should help you:
This is for the jerk who was in the right lane and wanted to turn left at the Sandyford roundabout (under the Luas bridge) across me who was in the (correct) left lane to go straight. The driver of the big Audi beeped his mighty horn and shook his fist at me - clearly I in my small VW Golf was in his way. I wondered what I had done wrong. Hey jerk - if you want to know what you did wrong, just look at the RSA video.
