The Association of Chief Police Officers will tell you that unrealistic speed limits are unenforceable.
A good example is the Farnham Road out of Slough. Approximately 30 yards either side of each and every set of traffic lights (at least 6 sets I can remember) the speed limit is 20 mph. I have yet to see anybody take the slightest bit of notice of this pointless piece of nonsense in the name of road safety.
I generally do stick close to speed limits, especially in built up areas, but I shamelessly ignore the sort of nonsensical limits that I have just described.
I agree with your sentiment but lets have realistic limits and then enforce them effectively.
How about at the same time prosecuting those that sit in the middle lane of the motorway when the near lane is empty, those that no longer use indicators (more prevalent by the day) and those that drive just plain badly.
It will be far more effective in the long term at reducing casualties but of course will provide little instant revenue.
