[Fixed] [2.17] Iceland, roundabout bug

[TescoclubcardUK]

I have circled the problem in the picture, the problem is, on this roundabout, A.I trucks are getting stuck and failing to go round the roundabout and on to the bridge, happened the 3 times I drove there, it's like they have missed the turning by still attempt to turn and then get stuck on the central reservation/grass.

Looks like I've fixed it while making slight upgrade of that area. 15 minutes with increased traffic and everything works fine
