I don’t think they do it deliberately. They just don’t look and think ahead. There is less traffic here and many learnt to drive in the country and are freaked out by the Britannia roundabout. They would not enjoy driving in the UK! I was recently in Colchester and my is that place complicated to drive round. The famous magic roundabout certainly had me confused and I wasn’t the one driving that day (thankfully it was a local).
