Spoke to a taxi driver here in town, he was pretty tired of them. Our small town has 70+, he had counted them... But they do make trafic smoother if placed right. Here however they use them instead of the normal highway crossings with elevated or lowered access roads. As you say, they cost much less and lowers the accidents a lot. But they are not fuel efficient on 80 km/h roads where you have to stop every 500 m because of another roundabout.
