That surprises me what you say about roundabouts, I assumed you used them of old. They are fraught with problems, not least because they are not all the same; some have multiple approach lanes/exits and when these ones are in the middle of a big city with the arrows on the roads indicating your direction of travel obscured by other vehicles... well... mistakes are often made. I make them, so I don't profess to be the ideal road user, but I am a careful one
