Never underestimate how confused people can get with the unfamiliar. I live a couple of blocks from a fairly standard roundabout and see people trying to exit the roundabout through an entrance to the roundabout or try to go clockwise in the roundabout (this is in Canada) several times a year. This happens even though the design of the roundabout, the road markings, and the signage make it perfectly clear how you are supposed to go through it. Then there is the less obvious stuff that happens multiple times per hour, like entering in the wrong lane given the desired exit (even though it is marked), vehicles inside the roundabout yielding to vehicles entering the roundabout (even though there is signage), or vehicles entering the roundabout failing to yield to vehicles inside of it (same signage). As for non-standard roundabouts, those can confuse just about anyone since people often don't realize that it is a roundabout.
