Play, hysteresis and compliance

Too sensitive initial steering response may cause some nerve fatigue of driver. In order to make driver feel so to speak safe and stable riding taste, an adequate amount of  play might be required in some portion in steering linkage or the axle construction compliance, of course the function is basically different from Hysteresis.
The less compliance in axle construction design might be introduced, the more precise adjustment and the more firm establishment of wheel alignment and axle constructive geometry are required, so the designing on the distribution of compliance is the key to decide the riding taste of the automobile, the number of combination of them are unlimited on earth.
Not a many experimental trial would be performed and be tested repeatedly by many officials before rolling out of the model.
