Good luck with that reply. There are few groups who can spin and twist and dodge like the Scammerati. They are more full of shit than your local sewer rats.
One question that's always interesting is:
"Can you tell me what were the causes of the crashes that have "justified" this camera?"
That usually takes around a year to answer, with repeated e-mails to and fro.
They'll hide behind the discredited "30% of crashes are speed related" DSA fudge, then, when you ask again for the specific causes of the crashes at that particular site, they'll try a few more fudges.
Then you'll get "we don't hold that data". That's neat - so they don't know what the causes were, but they've decided a camera's the answer.
Then, when you keep asking you'll get fobbed around a few more people. You might - as I often have - try a Freedom of Information request. They'll try to dodge that one too, and tell you the information is already in the public domain (even though they still don't know where you could find it or what the causes are).
Eventually, you might be able to get the causation stats (as I did for the M4 cameras) after paying nearly £700 for the data because it was "onerous" for them to produce it under FoI.
Then, when you finally get the stats that clearly show the causes of the crashes were inattention, looked but did not see, distraction and carelessness - and that speed had nothing to do with it - they'll come back with "ah - but that was just the police officer's opinion who filled in the form".
And, as soon as there's any decrease in crashes anywhere near a camera, they'll be in the local press trumpeting their success. Of COURSE they'll be a reduction in crashes - try looking up "regression to the mean", a basic statistical phenomenon. But when crashes go up again - as they often do, year to year, you won't find the Scammerati offering any answers.
Fecking marvellous - they do what they like, they're unaccountable, unelected, pointless and complete one-trick ponies.
"The answer's a scamera - now, what was the question again?"
