One has had a tyre fitted over it and lit up so possibly not working now as it is very burnt.
Most police forces agree that the cameras have caused many accidents and are not using them now. The A38 camera on the bend has been removed as it caused danger to the people maintaining it having to cross a dual carriageway on foot on a 70 mph stretch.
^ cameras on one small town had very little to do with safety and all fitted on steep hills.
The mobile camera used on the Exeter to Exmouth road 1 mile near the town is parked up by driving along a public pavement. Apparently the police are allowed to drive along pavements but joe public cannot. However, since these vans began to park on it, now the householders have joined them and now park on the pavement.
I have had one speeding fine by camera in 51 years driving. In Wales on a motorway at 70 mph dead on but a 50 mph temporary limit was on at the time. 60 pound fine and 3 points in the post.
Cars, i rarely speed and just set cruise control to the limit. Motorbikes, i do speed a bit on open roads where there are no pavements of people walking along.
Speeding never killed anyone, but, hitting a wall usually does the killing when you suddenly stop
