What is the purpose of steering wheel free play?

[Robin]

The functions of steering wheel free play: 1. Driving safety: Most family cars are equipped with steering wheel free play to ensure driver comfort and driving safety. 2. Slight steering wheel movement: During driving, the driver's hands must hold the steering wheel for extended periods. No one can maintain a completely static posture—tiny movements of the arms or fingers, or switching hands on the wheel, may cause slight steering wheel movements. The free play is designed to ignore these minor movements, preventing them from affecting the vehicle. 3. Maintaining straight-line driving: This play helps maintain straight-line driving, but it should not be excessive. Too much free play can reduce steering sensitivity and precision. The optimal range for this play is typically between -3 to +3 degrees.
