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.
Most high-quality car controllers rely on three pillars of physics: car physics unity github

If you decide to write your own custom scripts using community references, your codebase should address three critical pillars of vehicle dynamics:
To evaluate the accuracy and performance of car physics simulations in Unity, we implemented a simple car model using PhysX and wheel colliders. We created a test scenario where the car accelerates, brakes, and corners on a flat surface. We measured the car's velocity, acceleration, and position over time and compared the results with analytical solutions.
