On a 'normal' bike, it's common practice to feather the clutch and/or use the rear brake to help stability when manouvering slowly. Does it hurt 'our' bikes to employ the rear brake to a very slow speed when in Auto mode? I imagine the drive pulleys will easily take care of the 'slippage' and maintain a smooth drive torque? But will this cause gearbox/transmission problems? It seems to be an effective slow-riding method in jammed traffic or when U-turning in a narrow road.
