So where is the followthrough

In any sport where you swing a stick to hit a ball, the concept of follow-through is key.
Don’t stop hitting the ball when you hit it, keep hitting until the ball is well clear of you.
But I noticed the other day how little 'follow-through' governments have.
I stay in Bedfordview. Residents on Kloof road complained to the council that traffic was speeding too much, and requested a solution.
The council took action, and soon speed bumps and traffic circles (AKA Sandton speedbumps) appeared on the road.
Which worked. Usually the "rebels" that cause speeding issues have low slung road cars that kak over speedbumps.

Great, the democratic process in action.
A while later, at a town council meeting, residents were informed that after months of fighting red tape and other issues, the speed limit on Kloof road had been reduced to 40kph.
Residents were not impressed. The councillor was surprised that hardly anyone present approved.
Why, well, I reckon it's because "phase 1"of the cure worked.
But as far as the council was concerned, after Phase 1: Speedbumps, came Phase 2: Speed limiting.
They didn’t stop to check on the effectiveness of their initial solution.
No follow-through.

I watch and love Top Gear, and (forgive my chronology, I watch it on my PC, not on TV) and they recently (?) had an interesting piece of information.
A number of stretches of road were flagged as high accident zones.
Insane numbers of traffic cameras were installed and maintained at cost to the taxpayer. A year later, the accident figures on those bits of road were still the highest in the country.
You could even argue that the cameras were 100% ineffective.
Now in a private company, a revelation like that would lead to, maybe, a dismantling of the program.
Paying for a useless system is a drain on company resources, rather put those funds into researching an effective solution to the issue.
But not in government.
They have no follow-through.
They're not spending their own money, and maintaining those cameras creates jobs, which is a good thing for a government to do.
The original point of the exercise gets lost in the exercise.
It won't be canned because it failed to achieve its purpose, because its purpose becomes itself.
And, as evidenced in Egypt with Mubarak, once you have a self-purposed system in place, it will fight not to be questioned and examined, since it has lost its original purpose and would fold under scrutiny.
So sadly I bring you a clear problem but no idea of a solution. I kinda wonder if the entire government has become self-purposed?
