I’m glad you liked it. I made this project because I wanted to quickly generate random tracks for my game Retro Racing: Double Dash. It’s still a work in progress but if you liked this you might like that as well :)
It’s great that you’re making your own racing game. I’ve uploaded this project source code to github https://github.com/RichoM/racetrack-generator. It’s a little limited but feel free to use it, if it helps you get started. I just ask that you don’t use the car models, please.
For the car physics it took me a while to find something that feels good to control, I tried both the godot’s VehicleBody node and the popular sphere-based model but they didn’t feel like F1. Eventually I found this article, which describes the “bicycle model”. This is what I ended up using and it’s by far the best solution I found (it’s also pretty easy to implement, which is a plus).
Anyway, good luck on your game and let me know when you have something to show.
