[wireties]

It is not a given that your motor is always traveling in the direction commanded by the Victor. The Victor can instantaneously change its output. But unless someone changes the laws of physics the motor cannot. And remember the relationship of Victor output to velocity (of the wheel) is dependent on the torque curve of the motor, friction, traction, mass distrbution over the wheel, dynamic losses in the linkage etc. (thus the beauty of a servo that can determine direction and speed)
