As long as one possesses a Shift Car or a Signal Bike, they are able to ignore the time distortions a Roidmude emits when active, unless multiple time distortion effects occur. Anyone who has a resistance to the Slowdown also transfers that resistance to anything they touch. As shown during the Crush Roidmude incident, some Roidmudes can involuntarily deactivate their time distortion effects when sufficiently damaged, which can be seen as a white dome retreating back into the Roidmude's body. During this time, Mr. Belt had warned Shinnosuke that even Drive can cause Heavy Accelerations.
