That claim of reduced fatalities is also getting outdated now, since the introduction of roundabouts with more than one line. Also accident rate for the cyclists is actually higher on roundabout than in a a standard intersection. So all in all, roundabouts are not as great as many insist and my beef with them and their supporters is that they keep bringing up the same talking points that were presented _before_ roundabouts started to be built on a massive scale and don't want to hear the empirical evidence about how these roundabouts actually work in practice.
