Roundabout but not quite

[Ketraar]

While I do love the now option toplace roundabouts in street crsings, they seem to not quite work as true roundbouts and instead seem to be curved crossings.

What I mean is that often I see traffic not aboyeing teh usual roundabout rule wheer anyone entering a roundbout has to give way to traffing within.

Traffic does the give way when turning left thing stoping in teh middle of a rounabout, creating traffic. In most medium traffic cases this is not an issue but seems that to get really effective rounabouts one has to still build them manualy.

maybe this is WAI and as such not a big deal, but if not then they may need some love in future.

So I had a bit of a try & error with roundabouts and must say its a bit of a fiddly thing. As mentioned above there is no real give way prio for roundabouts and instead the "right goes first" rule, which obviously breaks the whole point of having roundabouts in the first place.

First thing I found odd was that a lane is removed on exist, where I had a 4 lane one way road for the circle and a 4 lane 2-way road leading out of where just one lane was set for exit, to have 2 lanes exit the roundabout I had to place a road with 3 lanes in one direction. This allowed 2 lanes to be set for exit but still one lane was not used.

This seems weird and without a way to define turn per lane this is a bit annoying. Would at least like to understand why this is or if it's not intended.

The best set up I found was to use highway roads for the roundabout. This allowed the removal of traffic lights and stops. and have the incoming roads give way to traffic with the circle. Again missing an option to define give way or traffic priorities (Traffic manager where art thou?)

Any insights apreciated.

Traffic seems to be stupid currently. I have a big 5 lane 1 way street feeding into a roundabout that is a city cross where most of my main 8 line roads interesect and then distribute across the range of city areas. It is backed up forever and there is literally 0 traffic flow. Why? They could have 5 lanes flow, but instead everything gets onto the right most lane and only 1 lane and then do a right turn. Of course cars change lane in the last second which holds up traffic even more. Its simply a stupid design, no real world roundabout would work out like the ones in the game. Imagine you have 5 lanes to turn right, but everyone decides to not use the 5 lanes but only use 1 lane and converge frmo 5 lanes, to 1 and then stay on 1 lane, even when 5 are avaiblable....

not only 5 are avaiblable,...

big roundabout, 8 Lane crossing from all sides..... pure chaos as they change in last second from outer left to most far away right and then decide to make a U-Turn within the roundabout....

This is my city Roundabouts make it so worse then even when you take away xings people still cross I had a 4 lane then a roundabout but 20ft before it cars want to do u-turns in the middle of the road instead of going and using the round..what..no way to stop uturns 4lane with curb Fckj it still cross..same with highway exits don't matter how many lanes they will all move over at the last possible second..it is like NJ ..I thought the trafffic AI pre planed the most effecent route?
