Texas for example must have too much lead in the water because people seem to chronically get them wrong.
Indiana drivers seem to much better in general with a lower incident rate of "omg that guy almost hit me".
With this said roundabouts that service a fixed area, such as a neighborhood without much cross traffic seem fine in general. Whereas roundabouts in areas that pick up new traffic are far more prone to incidents. And god help you if the roundabout is in a tourist area.
One of the problems with roundabouts in the US is there are too few of them so you're always running into someone who has never dealt with one before which increases the risk of unexpected behavior.
Anecdotes are meaningless. I’ve driven in Texas where there were roundabouts and it wasn’t ever a problem.
Don’t forget that at a roundabout the risk of injury from unexpected behavior by other drivers is _lower_ than at a signalized intersection. There’s a good reason why the injury rate goes down wherever they are built.
