Well they do work if the roundabouts are massive in size, but that defeats the purpose of a roundabout, which is to get something put in place with limited cost and space requirements.
For instance in Holland they do huge roundabouts to support highway crossings with overpasses.
But yeah, on their own, small roundabouts choke
medium roundabouts with lights also eventually choke
And deconflicting traffic with overpass or tunnel nets the best throughput but has highest cost and needs the most space to implement
It's usually a case of "should have done it ages ago, but , no money then or now."
