No, I suspect this is about fiscal concerns. I've heard that councils get more money for lower speed limits (can anyone confirm this?)
Cannot confirm - but it does seem logical. They are forever reducing speed limits up here and "Manchester Evening News" yesterday stated that the Labour Party would impose blanket 20mph past schools and in residential areas if they gained control of the council. In the former - fine if at peak times, and in the latter - no real issues with 24/7 limit.
(Given current hostility towards scams and a number of recent attacks on PC Gatso - one wonders if they are being politically suicidal. But then again .... postal votes...... cynical? ME?

However, you do wonder if pedestrians see lower speed as "I can cross the road and have time to get across before the car arrives" or even if they get impatient waiting and misjudge the speed completely or even become lulled into false sense of security and even think that hit at 20mph will not KSI them!
As for your original question as to whether or not this limit can be enforced or not.... given fuller information - difficult to see how they actually could. Course - with a Prolaser III - anything is possible

Whether of not they could make it stick given the signage - perhaps with good lawyer.... may get it chucked out!
But given the scenario - not viable - and more than likely they will not policing it - unless you make lots of noises and request re the boy racing nuisance factor - and they being such fly-by-nights will evaporate before plod get there. Par for the course - mate!
In Gear might know more - of course!
