Have to correct you here. Steering wheel angular velocity does not tell you how smooth a driver is in the context of performance driving at the limit. Driving smoothness is incorrectly interpreted in this manner so often. If this was the case then the slowest driver could be the “smoothest”, rendering smoothness a non-performance characteristic. However, if you are driving below the limits of the tires, then yes smoothness can be indicated by steering wheel velocity, but what is the point in that?
“Smoothness” in this context relates to the transition of weight transfer, lateral and longitudinal loading of the car, yaw, etc. Being smooth can actually involve small but fast steering inputs.
