Drivers are poorly educated with regard to roundabouts.

New Jersey has eliminated them because they are horrible when traffic volume increases.

New Jersey didn’t eliminate modern roundabouts. Over a period of many years they eliminated almost all of the old traffic circles — which functioned like roundabouts but were designed differently — around the state.

Roundabouts are ideal for locations there a three-way or four-way stop would otherwise be used. I’m not keen on multi-lane roundabouts where vehicles must often change lanes within the circle to navigate through it. Those are accidents just waiting to happen.
