Just a thought.
If the cameras are set for HGVs they have to work for the long bonnet units as well as the flat face ones. As such they may be set at a height that will detect the front of the long bonnet and so get a picture of the number plate and not the end of the hood.
In that case they will also catch a lot of above average height vans, caravans etc.
That may be so Andy, but there are very few long nose wagons in Europe and in any case I think that the detecting of the number plate is quite seperate from and preceding the detection of the vehicle size.
The reason I think this is because when the flash occurs it is only a fraction before my right hand door post, sometimes so late that it is not even picked up by my very wide angle dashcam lens.
Of course with the rear flashes, one of the 3 on Friday was this type, it is picking up the whole vehicle as well as the rear plate, so that explanation does not stand up.
Several months ago I reported being flashed at 80 in a 90 zone down one of the steep banks on the autoroute south of Clermont Ferrand, and assumed it was because I was in the slow vehicle lane and the camera was aimed at that. I now think that it is the same phenomenon, it simply thought I was larger.
With my latest vehicle, a 4 year old Partner, the cruise control is pin point accurate and so easy operate each time the limit changes, so I am hoping for amende free, if not flash free, motoring from now on.
Much harder in Spain though where the limit changes are almost too frequent, both up and down, to react to.
Does anybody know if France and Spain have reciprocal agreements yet?
