Smooth wheel turning with mobile control or axis simulation Input.GetAxis("Horizontal"). How is it better?

Question

C++ / C#

Steering wheel control by pressing the "left" & "right" buttons. When pressed, I set bool left/right to true and when decompressed, to false , respectively. I need that when the turn button is pressed, the wheel turns smoothly and when unclenched, respectively, smoothly rises to position 0.
How I implemented it now

if (left && horizontal > -1)
                horizontal -= 0.1f;
            else if (!left && horizontal < -0.1f)
                horizontal += 0.1f;

            if (right && horizontal < 1)
                horizontal += 0.1f;
            else if (!right && horizontal > 0.1f)
                horizontal -= 0.1f;

The problem is that the wheel does not go to 0 when it is unclenched. There is always some degree of "underturn". Where did I go wrong? And is there another way without bikes?

Answer 1

For smooth turns, use the Vector3.Lerp/Slerp or Quaternion.Lerp/Slerp functions.
It's done like this
SmoothLookAt is a parameter that tells how quickly rotation will go to lookRotation, the same for movement and Vector, this is done in Update or LateUpdate
