Thanks with the C6 the AI work better It continues to alternate gas and brake, but less and it comes out faster from that curve although it is still a problem if you are close to them because brakes suddenly at a point that you do not expect. I drove on a slightly different line than the one I've always used, probably is not the one suitable for them. for now I am satisfied maybe I'll try to improve that curve further next step: the cameras. (I observed those of Montecarlo while I was there and I begin to understand how they work ) There is still the issue of blue corridors. I redid "Find corridors" but they remained so. I will try to change the 3D in that area. I will try to merge the grass with sand.
