Isn't it funny how nobody questions any of the data in this "so called" report because the general point it is trying to make is "Speed cameras are a waste of time".
If however this report (like so many do) say that they do make a difference then this thread would be full of people questioning all of the data.
Well, the flaws in the statistics used to try and justify speed cameras have been well known and well publicised for a long time (ie lack of regression to the mean analysis, stationary injury/death figures, increased injury/death figures in roadworks with cameras etc). The big news here is that it's finally a government report recognising the problems everyone else has seen for a long time.
As I'm yet to meet any driver who is subjective enough to look at both sides of the argument we'll just continue to go around in circles.
A report says they help (Boo, Hiss, it's lies I tell you, all of it) then another says they don't (All truth those reports are).
So long as each camera saves just one life it was worthwhile installing.
I'd disagree with that, because cameras have to offer a net life saving value over alternative techniques as well as cost efficency. Due to the fines, they are cost efficient, but there is very little evidence that the do actually save lives, and there is also evidence that since the focus on speed as the answer to RTA's, the KPI figures have stopped falling year on year, or stopped falling as steeply.
I'm not adverse to correctly placed cameras (outside schools, or in areas where speed is a clear problem, normally because the road is deceptive), but there are much better ways of saving lives in most other areas.
Look at the accidents used to justify camera placement on the M4, out of them, one man jumped off a bridge, another involved HGVs hitting each other due to high winds, there were tyre blowouts and a car driving the wrong way. How the bloody hell any of these are supposed to justify a speed camera I have no idea, and how a speed camera is expected to save lives in that area is totally beyond me.

Speed cameras are a very bad tool for trying to save lives, because it's not speeding that causes people to lose them. Spend the money treating the cause of crashes, and you'll save many more lives. You say a camera saving one life is enough to justify it, but what if the alternative was to save 15, but the camera is easier?
