Torque is the correct measure to be used. If the person is touching the wheel but not applying torque how do I know it's actually not resting his hand at the bottom? I wanna know that the person is there and moving the steering wheel. Since in case of anything happening I need them to move the wheel not rest their hand somewhere.
