Driving M4 (from M25 to Bristol) went through about 4 sets of average cameras, now I sit bang on the speed start to end, what amazes me is the number of people that a) still slow down for the actual speed cameras, or b) ignore them completely. In general conversaion I've never known anyone got caught by them - anyone had bad luck on this front?
Average Speed - Anyone Been Got
- Thread starter T3Jn

Good question! I keep wondering this, usually on that same stretch of the M4 which has three or four average speed sections... quite a few people do seem to plough on regardless! Most do stick to 50mph though.
you can travel through the M1 roadworks (Jn 25-28) at 65 mph with no consequences (allegedly)
but if you get off at a junction in between they would miss you...Taz x said:
also they will measure your average over a shorter distance so you couldnt do the first part fast and the last part slow...
Ive never been caught on any speed cameras or anything... in the average speed cameras I use Cruise control...
A77 in scotland they have them. They work in pairs and in lanes, so in theory(but wouldnt like to test) you can tank it in inside lane then switch to outside lane before camera and it wouldnt "get" you!!!??
Also they dont work from first to last in a large line of them only from consecutive cameras to the next.
Pointless tbh :roll:

WOW :headbang: and people in the States gripe about police monitoring the toll roads...when the police around here only pic up the folks going more than 10mph over (like 80mph in a 65mph zone). We have no camera systems in place that take average speeds, just cameras that click you going through red lights.
Have fun with all those cameras!

I'm also surprised how many people just tank it past me when I'm sat at 50 on the nose through average checks!
I've been flashed a couple of times by cameras, but never got a ticket... last week saw a great sight on the M6 toll; Aston DBS pulled 'got' by unmarked black M5... oopsy!

The money is not the issue, they want to award points as well (and go through incredible loops to provide those as well, including having the law for motor offences reversed, i.e. you are guilty until proven innocent).
The M6 toll should be without police to be honest. If you drive anywhere under 100, you are the slowest driver on that road.

My missus seems to think the cameras cant catch you if you shift lanes. She was a Copper
I have tried the theory an and i have never been booked. These cameras are a bastard as i have to go through them on the work commute. Its like slow torture. Anyone know when they are removing them???
M6 Toll is being used for hunting by traffic cops. Watch out for the fit bird in the R32 and the M5...

I haven't yet to my knowledge. But I've heard it's so difficult for them to give us tickets they usually don't bother(not that I believe that). Either way I use cruise through average zones and use the car CPU to help calculate avg speed.
I did get flashed by a regular camera in Scotland....how likely am I to get a ticket from that?

This switching lanes business on the average speed cameras comes up a lot so I thought I would just put something here in case anyone was thinking of giving it a go.
Each camera looks at one lane and reads each number plate in a stream of cars going past at x mph. I used to be a programmer and the bit of software that does this trick is quite impressive. I did a bit of work on this type of stuff in the past and its not easy (OCR and voice recognition for my sins). The software basically figures out from a still frame which bit of the picture is the number plate and then figures out what your reg no is. Add dirt , weather conditions and variable lighting conditions and the fact that it can do it at all is why its quite impressive. It should be helped by the standard size/font/spacing but we all know not all plates are strictly standard.
Now what people are saying is that the computer which has a list of number plates along with time data and camera set/camera number can't match up a plate in lane 1 with a plate that was in lane 2 or vice versa. The bit they are interested in is the plate, the camera set and time. The camera number (lane number) is pretty much irellevant. The bit of code to find your plate in the database along with time and camera set (distance to last set is known and therefore time difference is known) and figure out whether you exceeded a speed limt is a simple time calc that I would expect a secondary school sutdent could knock up in there first year of computer studies. After doing all the hard work of getting your reg number I doubt they would fail in assigning you your 3 points becasue you passed camera 120/2 instead of 120/1
If you are going to gamble three points don't do it on a computer failing to match a string numbers and letters in a database

Couple of points that might clear the SPECS 'myths' up.
- The old ones used to only be able to monitor one lane due to Home Office type approval - however they are capable of monitoring more than one lane at once.
- They are used in pairs, and not necessarily with the next unit along the road (i.e. you could have a set of 12 over 30 miles and #1 can be paired with any other).
- They're 'probably' set not to send a ticket out unless you're over the ACPO guidelines of 10%+2mph, so in a 50mph stretch you'd have to be averaging 57.1mph to get a ticket.
- Most speedo's are not accurate at that speed and thus if you're sitting at an indicated 50mph you're probably doing 45-48mph - that's why the others driving at 56.9mph seem to be shooting past. I set my cruise at a GPS-indicated 55mph.
- Supposedly - from someone who installs them - they're not all active. But as you won't know which ones, you'll have to play safe.
