Another curiosity with Sweden is that priority to the right has been codified in law since the switch to right-hand traffic, but has never actually been practised by motorists. Instead they have a bunch of unwieldy and dangerous ad hoc rules, such as priority-to-the-crossbar-in-T-intersections and priority-to-the-slightly-larger-road-in-4-way-intersections.

Also confusingly, when Swedes are about to make a left turn they keep to the far right instead of the more logical left, and vice versa.
