I was blown out of it yesterday by a Dublin Bus, i was only going 80 and he was annoyed I hadn't held back to let him join the dual carriageway, I was too busy concentrating and keeping eyes all around in the heavy rain. He then tailgated and kept his full beam, until he eventually had to pull over for a passenger. I regularly let buses out in the 50 zones as I think it's good to do so as it helps keep them on track of their timetable, but yesterday it was safer for me to proceed and him to slow and go behind me than try barge out from where he was joining the road, I'm not sure everyone realises the full rules of the road...
