I would say unnecessarily over-sampled.

Original roads were edited in 2013 and imagery all showed this as a
roundabout, as confirmed by the TMR dataset so I updated it from TMR.

+1 to the operator tag in this case. In fact that's something we could
use this source for, to add operator=Department of Transport and Main
Roads + operator:wikidata=Q1191482 to all of these roads.
