If you just rotate both front wheels by the same angle (the default Unity approach), your tires scrub against the asphalt, fighting each other. This creates a "juddering" feeling at low speeds. Quality GitHub repos solve this with a simple trigonometric function that splits the steering angles, making the car feel grounded and heavy.

Before writing code, it is essential to understand the core forces acting on a vehicle. A realistic simulation balances these forces to create stable, predictable driving dynamics. The Foundation: Rigidbodies and Mass car physics unity github
GitHub is home to excellent open-source vehicle physics setups ranging from simple arcade scripts to high-fidelity simulators. Edy's Vehicle Physics (Community/Legacy Versions)
Suspension keeps the vehicle stable and ensures tires maintain contact with the ground. It is modeled using a spring-damper system: If you just rotate both front wheels by
