Simple cruise systems only monitored speed and would throttle the engine to maintain the target speed.  When a loss of traction happens, the proper response is usually letting up on the throttle so traction can be regained.  These old, simple systems would apply more throttle insuring a mere slip turns into an epic spinoff event.<p>Secondly, when driving in spotty traction conditions, it is good to use a lower numbered gear and a safe speed combined.  That same loss of traction event can result in a very rapid spin of the tires due to the higher gears and torque combining to produce a rapid increase in tire spin rate when not constrained by the weight of the car and traction.<p>This can happen before a human can respond.<p>The higher gear puts the engine at a higher rpm and closer to it&#x27;s natural unconstrained speed, which diminished both the event and it&#x27;s impact considerably.<p>The human experiences momentary chatter as the grip of the tire varies, but does not experience runaway spin and the abrupt loss of control it brings.<p>I would think an automated car could be programmed with this all in mind and do rather well.<p>An awful lot of humans could use this kind of data programmed in as well.  :)
