When operating the lever, the force is evenly applied with a rebound effect. It avoids being too loose and causing accidental contact or being too tight and causing difficulty. The operation feels clear. The steering command is triggered quickly, and the wrist can complete the operation with a small movement, reducing the risk of distraction while driving. Whether turning left or right, the operation force is consistent. Long-term driving does not have the cost of adapting to the feel. The surface of the lever is treated with raised and recessed textures, which prevents slipping in rainy weather or when there is excessive hand sweat. The operation is more stable. The lever needs a certain amount of force to trigger the steering, avoiding accidental activation due to unintended arm contact during driving.
