I once went through one of them at 60 once, but I then crawled through the rest at about 40. I got away with it. I think you should be ok.
#2
you did half a mile in the first half a minute.
#3
yeah, my maths is pretty good, 60 mph is half a mile in 30 seconds....?

otherwise known as 60mph

You should find out in about 14 days if you are gonna be fined they are normally quite quick in notifying the owners of the vehicle

depends how far the cameras are apart... 60 for a minute in a mile set of cameras, = 60mph average.

60 for a minute in a 10 mile set, doesnt.....

unless you know the set of cameras, it could be any 'average'

I would assume it is measure from one camera to the next, not over the whole set.

Right.

I thought you were worried about doing what you did between camera a and b (for example).

Different cameras can be turned on at any one time so could be safe, could be not. I wouldn't be overly worried though.

yep, the op says the cameras are for about half a mile. Therefore based on the figures most likely speeding in it and the rest is irrellevant.

Yep, but syas he got half a mile (65 in 30 secs) then went at 45 until end, assuming end of cameras. If that's the case, his average was below 50 (about 47mph) so he should be ok...

oh, thought it was only half a mile?

use the lane changing system next time ;-)

We have variable speed limt average speed cameras on the M42 and it is a common 'myth' that the suppliers were not paid for the upgraded system that tracks lane switching, so therefore the story goes if you switch lanes it cannot track you.

We have now just had some installed on the M6, whenever the variable speed limit is in force the message boards always say 'congestion please stay in lane' and I think this is so that the cameras can track you.
#17
I doubt that's how it works, if it does it's a shoddy system.

All the cameras need to do is send all lanes back to a main system which works out which car did the distance in too quick a time and then flash the camera on it.

Simples.

Cynic. It could because there is congestion (hence the reason the speed limit is in force) which is made worse my lane changing.

But if you switch lanes between camera A and B it does not track you(apparently).

It only tracks between camera A and B on lane 1, not between camera on lane 1 and camera B on lane 2.

Most of the time only lane 2 and 3 of a motorway are covered at all.

So the story goes they had the option to upgrade to the 'lane switching tracker' system but didn't cough up for it.

Don't know whether it is true or a myth, guess there is no way of knowing. If it ever came out to be true though it would be like a dodgem track.

What I can't believe is the amount of drivers that pass me doing say 60 in the 50, do they switch, do they know it's not working or do they get a fine. There seems to be an awful lot of them though that do not seem to be heeding the signs and I always wonder why.
#23
i dont know if its true about the different systems all i know is that when i came back from up north i did 80 through the m1 avg check and didnt get a little letter through the post (about 2 months ago) funny thing is when you see people speed then slow for the camera DUHHHHH

IT's a myth. There's a stretch of road between Stirling and Glasgow with these cameras, 40mph limit due to road works. There's a lot of people going above 40, and switching lanes when they can. I wondered myself, got a friend who works for the procurator fiscal, and apparently there's hundreds of people caught by these cameras every week, lane changing doesn't work, and they're switched on 24/7 apparentyl (another myth that they weren't)...
#25
So the next question is do variable speed cameras pick up over 70 mph when the variable speed limit is not in operation?

Are they on all of the time?

Has anyone ever been done by a variable speed camera that wasn't in variable speed mode.

how did i get through the m1 ones then??? i think it all depends when you switch lanes how long you take etc couldnt be sure im no camera-oligist but it must make a difference?
#27
System to system maybe different perhaps some cough up for the lane switching software.

Back when ASC were first out, if you changed lanes it confused it and it didn't clock you. I'm sure they've probably fixed that bug now though, well you'd think so!
#30
I don't know anyone that has ever been caught by an average speed camera - Has anyone here (directly to avoid hearsay and conjecture etc) ever been caught on the average speed checks on the motorways?

I also heard that switching lanes confuses the system. I regularly go through an average speed check on the motorway at more than the advertised limit when the road is quiet and have never been caught... not normally that lucky, so I think that the system is more of a check than enforcement!

OP - I suspect that you won't get a NIP (Notice of Intent to prosecute); they have 14 days from the date of the offence to contact you.

Good Luck!

Not sure what you mean with that comment ... The average speed check is on the M3 where there are NO roadworks and at 11pm at night is totally empty. If I am not doing anything dangerous and the cameras have not as yet caught me why should I do 50MPH?

I don't condone dangerous driving; however there are organisations that lobby the government to lower speed limits everywhere. Speed does not generally kill, dangerous and bad driving does which can happen at ANY speed.

I am firmly on the "Jeremy Clarkson" school of thought on this one

Switching lanes DID use to work, as the cameras were only type approved for one lane, even though they could monito moe. However now it doesn't, as soon as it came out, the SPECS (average speed cameras) were upgraded in type approval to work on more than one lane.

So it did use to work, and now it doesn't. Hope that clears things up.

Spot on with this,swap lane 2 lane does not work now,and it goes from cam 2 the next cam so your average speed will be between them not the whole area.

I meant the fact that you regularly deliberately flout the law by exceeding the speed limit isn't very bright. Whether the road is quiet or not, if the limit is in force you should obey it. If you don't then it's only a matter of time before you start clocking up some points.

LOL .. I have a clean license and pride myself on being a safe driver for over 23 years ... sounds like you are from the "rules is rules" school!

Each to their own :roll:
#38
^^^^ Why is the M3 speed limit set to 50mph at 11pm if there are no roadworks?
#39
Because they have come up with a great new traffic management scheme for traffic merging from the M25 onto the M3. Which is in force even when there is no traffic to manage .. great idea eh?

Nope, not at all. If you knew my last 6 cars you probably wouldn't think that.
I was just pointing out that you seemed to be gloating about how you keep getting away with breaking the speed limit. I was saying you won't get away with it for ever.
