I wouldn't use that.
Have your hands at 10 to 2 on the steering wheel, both hands lightly holding the wheel, fingers gently curled around the steering wheel rim. At this point keep the grip light and focus on keeping the same amount of pressure on both hands so you can keep the steering wheel absolutely still by balanced equal downward light pressure (the weight of a hand) You are now travelling ahead in a straight line.
If you want to change lane to the right, just allow a very very gentle pressure to rest on the right hand. Let the weight of your right hand do the movement and work and let the left hand relax or be 'open'. You probably only need about a millimetre of movement downwards on the right hand, a really gentle pressure, (not a tug or a definitive movement) When you are in the new lane on the right let the wheel very gently return to its straight ahead position (10 to 2) ready for the next lane change (probably to the left)
If you are changing lane to the left, let the left hand become slightly heavier than the right, and about a millimetre of pressure downwards biased onto the left hand (and gauge the success by the drift across to the left)
All lane changes should be smooth, particularly at higher speeds as it is important not to unbalance the car and create a skid (by coarse heavy steering movements) If you are rough or panicky with steering you will lose control of the car. The amount of steering wheel pressure downwards remains the same according to a standard lane change. But the speed of the steering application (lag) from turning the steering wheel to the turning of the road wheels may change according to the m/sec ground speed.
