they have just installed these in the lake district along a dual carriageway. the dual carriageway is alongside a lake and is about 2 miles of just twists and bends.(50mph limit) before i enter them i always hit cruise control at about 49/50 mph to make sure i dont go over the speed limit. Now i was wondering as i overtook a couple of vehicles while going round the corners(it more or less meant i was straightening the corners out to make it a straight road) i was wondering that if a car travelling at 50mph going throught all the bends on its own side of the road and sticks to 50 must be ok, but what if you straight lined the dual carriageway all the way taking the shortest route possible would it mean you would average a greater speed from a-b, maybe although you didnt go over 50mph? bit like taking a short cut.

 

I woul imagine there is some tolerance. If you set your cruise at 50 what does your speedo say, cos they are normally optimistic

 

You will find out next week

Actually quite an interesting question.
If you new all the theoretical tolerancing, ie say 10% allowance and set the cruise control against a really accurate sat nav speed reading of 55mph, so a true 55 which if the camera was set to 10% shouldnt see you caught theoreticaly.
Basically the question has to be how much effort is put into the setting up of the allowed time to cover a stretch of road.
1/ the supposed route
2/ the actual quickest route a-b that was possible
3/ the actual quickest route without breaking the rules of the road

Personaly i always set the cruise control thru specs cameras and know most of the common speeds real speeds off my sat nav and set the cruise control to them rather than my speedo reading, ie 60mph is 64 on my speedo and 70 is 75 (as near as damit lol), just doing that and not pushing for the 10% tolleraance normally sees you passing most things quite well lol
As a side note, everyday I drive to work along a 70mph camered road, and nearly every car is driving along at about 65 mph and as soon as they see the actual camera they brake ??? WTF its not like it just one and they might not be sure of the speed limit, there is like 5 along a stretch of a few miles, so its like 65 brake 55 accellerate back to 65 camera brake 55 accellerate back to 65 etc, pisses me right off !!!
