3D City traffic simulator

A city traffic simulation prototype made in Godot 4 that can evolve into building cities that have the best traffic flow and human welfare or directly controlling the flow of the traffic to satisfy the drivers and pedestrians or any other idea :).I have uploaded the project to get reviews and suggestions so please let me know what you think. This is a hobby project that I eventually want to make into a more complicated simulation game when I have the time and the funds :')
