Alrighty, I decided to actually use my brain and came to the conclusion to instead bake the racing paths, instead of just having them create one at runtime. I made a small unity tool, I just place the checkpoints, click bake and a racing spline gets generated. If you look real close, you can see that the line follows an outside-inside-outside path for steering. Now that I have this, I will work on the racer Ai itself. First I will make it follow the track with optimal speed and then teach it to avoid obstacles, other cars and then even overtake.
