For sure, though "it depends" comes into play. Roundabouts down scale well beyond 3 lanes and if one gets clogged up it can have a butterfly effect that causes clog ups at other intersections At least with a standard crossing intersection of say the E->W road is hosed up because of a traffic accident the other flows of traffic are unaffected as long as the intersection remains clear. Even if some jerk gets stuck in the middle they have the ability to U turn out to unblock the intersection. With a roundabout when it's not clogged its very nice and I do enjoy them. But I've also been stuck at an intersection for more than an hour because of a fender bender in a roundabout causing a full traffic stoppage with no way out.
