Basically, the curblets prevent people from changing lanes once in the roundabout, but emergency vehicles can still easily mount them if need be.
I probably should Y-split the roads where they touch the circle to allow for a smoother transition into theroundabout instead of the sharp corners, but you get the picture.
I mean, the whole point is NOT to do that in order to slow traffic lol. For a turbo roundabout maybe a little contouring is expected. FWIW, I think islands on the four lane road would be appropriate, crossing four lanes of traffic is pretty dangerous. And I'm not sure of the scale, the crossings feel pretty far from the circle.
I'm curious, what did you use to create this? It looks excellent!
