A very interesting court case in Swindon this week - I know that sounds unlikely, but in this case it's true.
A salesman was summoned to court for speeding. It was alleged that he was doing 59 in a 30mph zone.
The driver was convinced that this was not the case. He took the police to court to demonstrate their mobile speed cameras can produce wildly incorrect readings in some circumstances. (The police hold this is only when equipment is used by untrained personnel). Anyway, he won his case!
If the laser fired by the mobile camera "slides" or "slips" along the target vehicle (a few milimeters will do it) then a false reading can be obtained.
The local tv news (BBC Points West) ran an experiment and found the same issues - in one instance, they even clocked a stationery vehicle at 72mph!
After hearing this, I was driving along the motorway and noticed a vehicle on the bridge scanning the motorway. Let's hope those bridges don't move by 1-2mm or the camera mounts, or the cars on which they are positioned.
Given this, how realiable are any mobile camera readings?
(Before you all complain, I'm as opposed to dangerous driving and reckless speed, but I am far from convinced about the current policy. It's strange that most of the locations around my area are high volume roads rather than continuing blackspots)..
I suppose it's back to the law being there to protect rather than make money
