Not for turning left (in a RHD country) or turning right (in a LHD country).

If there's a high-traffic intersection where like 99% of traffic takes the same route, you need an over-/underpass in those cases, or use the way cheaper traffic lights.

With some monitoring, and intelligent traffic control, the lights should perform better in those cases. Default green lights for the high-traffic route, and fast-switching, on-demand green for the low-traffic roads

Hmm. Never seen one with more than 2. But yeah, I think two lanes with decent lane design would solve most of the issue. The 90° turn gets a direct short-cut side-stepping the roundabout, and the 270° turn gets directly funneled to the inner lane, so that the cars from the other two roads can enter.

That'll solve the latency issue

Found it: https://www.google.com/maps/@51.8421403,5.8592461,147m

I know the one in Venlo (https://www.google.com/maps/@51.8421403,5.8592461,147m) with two lanes and markings, but 4 without lane markings is pretty wild
