I believe the statistics for cyclist collisions on roundabouts are actually rather worse than for other types of junction, and this is thought to be the reason.


[1] Assuming we're talking about the overwhelming majority of the world population who drive on the wrong side of the road.
Inspiring discussion of Sharknado is not a good sign for the audience expectations of your new high-concept SF movie sequel.
