when you're on the quieter stretches of motorway it is relaxing just to take your hand off the throttle, relax your grip, allow you to maintain a fairly constant speed with out the usual wavering of speeds
if you don't like or find it an "obsession" then fair enough but as i'm on thing everyday its helpful just to have one extra device to assist
i don't understand obsession with six axis imu, tft screens and connectivity but if that makes you "safer" or more complete then fill yer boots
