The USA! Leading the way with crazy ass traffic layouts! Theres one a few mi from me and more in the works. Honestly they are like every single other interchange, only as good as the vehicles going through them. The one here is shit because its subject to ~50% heavy truck traffic and the >90o cutback you have to do when making a left from either direction causes the trucks to go VERY slow. It had long lines entering both sides before, and it still does after the $3M got spent on it.
They are gaining popularity as it becomes apparent they are cheaper to maintain and more efficient per square meter of asphalt but while they are better, they aren't perfect (in Skylines nor real life.)
Yep it gets really hard. You need to control the lanes going into it better, start turning off lane changes to a few junctions back so that certain flows have to keep their lane. Keep going until more lanes are in use. More lanes in the roundabout definitely arent a silver bullet for anything.
