Portsmouth has introduced a limit of 20 mph on most of its non through route roads. Motorists appear to obey it despite the absence of "safety" cameras and it is my understanding that no speeding tickets have been issued (as of late October). I believe most motorists are responsible and drive at a limit suited to the area and weather conditions. In Hampshire this is hampered by speed limits of 40 on single lanes, then 30 on dual, 40 approaching a roundabout all within a mile - no logic and of course lots of fines, for where better to put up a portable "safety" camera.
