Kia Ora,

Im from a chunk of Australia known for a tonne of roundabouts and observed the same issue. My theory is that this is actually roundabouts working as intended, despite the frustration of the South-Enterers.

Basically, if the flow of traffic is both moving too fast and with too great a vehicle density to allow for safe entry (even if slow, like 1 SouthBound Vehicle for 5x Northbound + 5x Westbound) then the traffic organism is actually distributing resources based on need, rather than convenience. The flow WILL automatically correct itself as the population of vehicles diminishes, the question is if the WAIT time for Southbounders (and the population of Southbounders) is sufficiently large that interfering with their flow is actually delaying more people than the North and West routes, but that is more of an issue of roundabout placement than it is the roundabout itself being inefficient.

(^^The above is all 100% observation and guesswork, anyone with some education on the matter want to chime in?)

It's a good load balancer for sure, but that doesn't help the poor sod who is in the minority who has to wait for ages simply for not needing to go the same direction as the majority.
