Average Speed Cameras
Discussion
Why are there so many cameras on the main carriageways when the road has average speed cameras on it surely they only need to be on the exit/entrances to the carriageway & at the very end of the average speed section.
It's a simple question that I'm sure has a simple answer, but the only answer we could come up with was a chance for extra revenue.
I hope PH can clear this one up for me.

If the cameras were spaced too far apart then it might be possible to drive quite a bit over the limit for part of the section, then compensate by slowing down for the rest of it to keep the average under the threshold. I'm guessing placing cameras closer together reduces the chance of that happening.
What I really don't understand is through average speed camera sections where you Dan clearly see them I put the cruise control on whatever speed the limit is.
However every single time loads go past WAY faster - now the question is are they all going to get tickets or do they know something I don't? I'd much rather be going faster, if the road conditions permit and nearly every time I go through no one ever is doing any work, and not not get fines and points.

A risky strategy should the speed limit also enforced by other means such as mobile cameras.Conscript said:

But surely that's the point of the cameras which is to keep the average speed by adding loops your limiting someone's chance to stay within the limit hence my gut feeling it's for extra revenue.

They're probably doing an indicated 77 mph to 80mph which equates to an accurate 70 mph give or take. They may be using gps to. You'll be doing 65mph ish?However every single time loads go past WAY faster - now the question is are they all going to get tickets or do they know something I don't?

Fwiw I've made several journeys through 50 mph average speed zones recently (99% of my journeys are low-speed ratrun commutes) and have carelessly drifted to well over 60mph for long stretches of them.
I blame rarely encountering 'average speed' cameras, lack of cruise control, and a general lack of attention/ rush to reach my destination for this motoring faux pas.
I've spent so much time doing 60+mph through these zones (and most definitely not slowing enough at any point to drag the average speed down) that I'm beginning to wonder how excessive your speed has to be to get 'caught'.
I tend to sit behind the slowest traffic (which rarely seems to be doing ~50mph) and am overtaken regularly; I too often wonder if they 'know something I don't'.
I've gone through so many different average speed zones on different days/ times that there is no way I can reasonably believe they are not activated/ switched off. I can only imagine how blazé I'd become were I negotiating these on a more regular basis...
Based on an admittedly small data sample (personal experience), I feel genuinely sorry for anyone who has been caught out by average speed cameras.

Can we stop with this b
ks please? Most normal cars are within 1-2mph of indicated speed vs GPS. Even at 167mph my car is within 1mph indicated. My other two cars are within the same tolerances. No car on the road is 10% out at 70mph unless running incorrect tyres imo.HappyMidget said:

isnt it more to do with the actual technology in calibrating the cameras that they allow for a 10% difference in your favour?ks please? Most normal cars are within 1-2mph of indicated speed vs GPS.

Yeah I agree. A lot of modern stuff now is pretty accurate & I personally haven't had a car that over read by more than a gnat's cock for a few years now. What happens is you get at least 10% plus 2mph margin of error on any fixed camera so using a crap nav for accuracy you can happily sail through at 78/67/56/45/34mph showing on said crap nav knowing full well you are in no danger of being prosecuted while waving politely at Mr. Welshbeef as you pass.
Edited.. Forgot to wave politely at Mr. Welshbeef.

To add some drivers in average speed zones get so close to your bumper trying to make you go faster? I don't get it. ? I'm not going to get a ticket due to someone else if they want to risk it overtake.
Tucking in to try and hide their reg from the camera if they've gone a little too quick?mygoldfishbowl said:

My "safe" motorway technique is to set the cruise to 79mph and i can safely assume i won't get a ticket ,whilst travelling with a big enough speed differential to not dawdle past those in lanes 1 or 2.

Yes i agree with this, my current car has only maybe 1 or 2 mph difference between the speedo and a SatNav reading.

its to do with the cameras and how they are calibrated, not the cars speedos.My "safe" motorway technique is to set the cruise to 79mph and i can safely assume i won't get a ticket ,whilst travelling with a big enough speed differential to not dawdle past those in lanes 1 or 2.
