The project was made in Unity 2019.2.12f1. In this project you can see, how the cars learn a given map. It's based on genetic algorithm and neural network. Don't worry, if you have never met with this kind of project, it's time to download.
All you have to do is download the project and open the SampleScene.unity file.
I made a documentation, that you can find in the Wiki/Documentation page, or just simply click here
