One day I was driving along a beautiful, narrow and mostly straight road in southern Utah, and noticed that I was making a lot of steering inputs. I focused on how the vehicle responded to them. Then I tried reducing the magnitude of the corrections by half, and removing the corrections as soon as it began to respond. In a few minutes I was staying centered in my lane with very little steering wheel movement.
Sometimes modifying the brains transfer function is easier and cheaper than modifying the vehicles transfer function.
