Yes, Phil, I overlooked your last point (and I have UK driving license). In Italy there are no separate rules or road signs for traversable roundabouts, hence no interdiction of U-turns. That needs addressing. Country-specific defaults?
"My" traversable roundabout is in fact often used for U-turns, but only by shorter vehicles. The articulated trucks I observe, are turning left, not U-turning, on a four-way layout.
