Apart from regularising a common occurrence, an uplift to 80mph will have little effect on average motorist's speed. It will not be any more or less enforced. It is not general policy to have speed cameras on motorways due to the potential for incidents if someone brakes hard to avoid the camera, Exceptions are road works and maybe some managed sections of road. Somerset and Avon used to do it and I was caught on camera in Scotland on the M74 about 10 years ago (on a near empty motorway and a clear sunny summer morning).
Having driven since 1970 and a large number of motorway miles, I have two basic modes of motorway driving. One is driving to the left staying in lane one and overtaking only as necessary aiming for steady progress between 60-70mph. Two is generally in the late / early hours on a quiet motorway where 80-90mph sometimes a bit more will be typical.
Mixing highish speeds with a busy motorway and less experienced drivers (try saturday morning on the M6 in Cheshire) is usually a recipe for disaster.
