I was driving down from Mayo to Limerick one day and of course DS wanted a toilet as I was on the motorway. So I took the first exit and started looking for a suitable spot to pull over for him... I drove around a good while before I found a quiet enough road with no houses on it and for a few streets had this car following me... Nothing weird about that, except when I pulled over, so DS can do his business, the follower car pulled over as well! I looked back and saw the driver looking confused, like "Why did we stop here??" She was so intend on following me, she lost track of what was going on and where she was meant to be going LOL When she saw me and DS staring at her, she quickly drove off.
Similar thing happened a few months before then, in a small village in Cork. A learner driver followed me so carefully, it tried to pull into a parking space with me! I looked in my rearview mirror to see the poor lad frantically trying to reverse, while his instructor is giving out to him!
Being followed by cars like that is not unusual here. The thing is, our roads are VERY narrow in places and with cars parking on the streets, space is tight at times and carving through traffic is often necessary. So we tend to tuck in behind another car, or if we're lucky, a bus or truck (they make more space) and let them figure out the route and space for us.
