Also it would appear that the further north in Scotland you go, the more polite the drivers are. I usually drive around Glasgow but for the past few weeks I've been driving to Perth and back each day - everyone is SO polite and well mannered - you get let out of junctions, let into lanes, if 2 lanes merge into one people don't race down the outside and cut in at the last second. Not what I'm used to! Makes a pleasant surprise for me
