DCC does work on rubbish road surfaces and is better than just having hard or soft suspension
Your "comfort", "normal" or "sport" settings are just initial damping. On comfort it will ride like a big car over bumps, potholes and speedhumps, but chuck it into a bend and the sensors will detect the loading and stiffen it so you don't get body roll like a 2CV.
Its called Dynamic Chassis Control for good reason - its not the older electronic suspension setting selector.
Its very clever, its very good.
Like much modern tech, some people don't trust the witchcraft, others accept it as a miracle.
