Okk, I feel like i’m getting close. As you can see, the car now tries to build a racing line, this is all in real time. While its still not perfect, I feel like I am getting close.

There are still some bugs related to the pathing on the road that I will have to fix, but overall its very good.

The system works by identifying an apex. The geometrical apex is considered in this case the point which has the biggest angle difference compared to its neighbours. Now, after it identifies the apex, it grabs all points leading to the apex, and shifts them to the outside, before starting to shift them to the inside towards the apex, all using a sine wave based lerp in order to get a nice arc. While this system is good, I feel like the driver script that is responsible with making the car follow the points is kind of goofed, so i’ll look into that.
