About the Game
AI Learns To Drive is a sandbox simulation where you can create and train your own AI to drive a racing car across different tracks. The AI uses a simple feed-forward artificial neural network and is trained using evolutionary algorithms.
Edit AI
Customize your AI's neural network. Adjust settings like the number of layers and neurons to see how they affect learning. Experiment with different setups.
Edit Tracks
Design your own tracks with easy-to-use track editor. Choose from surfaces like asphalt, ice, and dirt to challenge your AI in various driving conditions.
Training
Train your AI using evolutionary algorithms. Over multiple generations, select the best-performing agents to create new, improved ones. Adjust training settings like time time limit, learning rate, and the number of agents to optimize learning.
Challenges
Test your AI's skills in campaign challenges. Earn stars by achieving goals like completing laps within a time limit, reaching high scores, or mastering tough tracks. Each challenge helps your AI improve.

This update introduces physics engine changes, focusing on performance and determinism.
⚡ Performance
- Partially multi-threaded physics updates.
- Rewrote Godot's raycasting system from scratch (testers estimate 100-300% performance improvements)
⚙️ Determinism
- Fixed inconsistencies in the first generation, newly created cars, the wheel sensor, and after pausing the simulation.
- Improved determinism to ~99% (collisions remain non-deterministic).
🔧 Settings
- Added "Maximum Parallelism" setting to control thread count.
- Increased default max population to 800 (up to 3000).
- Added a "Lap Time" reward (set this to -100% if you want fast lap times)
🖼️ UI
- Standardized terminology (e.g., "Score" is now "Distance").
- Fixed lap time rounding issues.
