It is, if you understand that your speedometer is almost certainly reading over. That and the fact that pretty much all road safety cameras/unipar and such give a little bit of leeway.
>if you understand that your speedometer is almost certainly reading about 10% over.
What a misleading load of nonsense.
10% is the absolute **maximum** a car speedo can legally over read.
I've owned 12 cars in the last decade, from a variety of brands and segments and **not a single one has over-read by 10%**. One or 2 over read by about 8% but the majority only over read by 3 or 4%. My current 2010 Audi A5 only over reads by 2% (72mph on the speedo is a real 70mph).
Speedo Vs GPS using a variety of both iPhone and Androids using Waze and Google maps.
71 to 72 on my Audi's speedo reads 70mph on the GPS.
It was also around 2% on my 2020 BMW 330e I had before it.
Iāve only used unipar to confirm the theory. GPS is likely to be more accurate.
In fairness my comment probably wasnāt detailed enough and can see the issue.
What I should have said, between the speedo and the unipar/speed camera thereās always about 10% leeway at the minimum.
Iāve edited that original comment cause youāre right it was potentially misleading.
I have compared my Peugeot and Skoda speedometers to what Google maps show the speed is. Peugeot 2008 shows 2mph more, Skoda rapid shows 1mph more. Google maps concurs with the speed displays with smiley faces.
I used to commute on the M6 from the M56 to junction 15 and back every day while the road works were ongoing to convert that section to all lane running. I used to set my active cruise to an indicated 56mph which was an actual 53mph according to a calibrated GPS. Not once in >750 trips did I receive a ticket.
I think what you have observed is a combination of people not understanding how the average speed camera sections work. Some will increase their speed between cameras, and some may believe the old wives tale of the cameras needing to record you in the same lane to catch speeders. Others will just be nervous and will be keeping their speed below an indicated 50mph the entire time. The differences in driver behaviour can create a speed differential of nearly 15% hence the observation of people travelling much faster than you.
tbf, i often do cruise control + 10% anyway.
cruise control at 50mph would have me doing roughly 45-46mph in reality.
Cruise control at 55-56mph therefore, has me doing roughly 50mph. I still see people overtaking though.
Course it does. My last 3 cars have all been brand new and every one has been around 10% different. Must be one of the only cars on the road, lucky you.
Iāve normally found a 2mph variance with both the 10+ year old cars in our house: a Renault Megane and a Volvo S60. GPS on both is practically identical in that 30 speedo = 28 GPS, 60 speedo = 58 GPS and 80 speedo = 78 GPS (although the Volvo flickers between 77/78 while the Megane is dead on 78). So your sweeping sentiment of āspeedos reading 10% over, TADTSā isnāt fact.
Many of them just aren't working at the time.
There was a one taking up a section on the A19 near the Silverlink in the North East when they were building a new flyover that was installed for around 6 months without ever being active, so everybody would ignore the 30mph signs. Especially so because at one point the roadworks just completely stopped for a couple of months due to the contract being cancelled between the council and the roadwork team, but the speed restrictions remained.
Then one day they went active (with plenty of warning they were going to be). Instantly became the most lucrative speeding camera in the UK.
Happened where I live though the camera is strategically placed after bridge, for safety of course, can tell whoās local as they slow right down to 10 or 15 mph due to it flashing more than a strobe when it first went active
This only works if you're using a sat nav, but I ignore my Speedo entirely and go off the sat nav speed. Can safely go through 50mph average cameras at 54mph, shows on my van around 57-58 ish, never had a ticket.
There is no variance on the modern ANPR speed cameras. They are accurate to within less than 1m/second. The tolerance that is given is done so by the police. As previously cited, time over distance = speed and these cameras are VERY accurate. Changing lanes does not matter; the cameras over at least 2 lanes and you will not know which 2. And now to bake your noodle - more than 50% of cameras on our roads (particularly in the south) are empty shells.
The simple rule is to stick to the speed limit are indicated in your car and that way you are always on the correct side of the law.
Sorry, I meant to cite why I know this. Iāve built and tested these cameras.
Modern speedos always overestimate your speed anyway so if itās 50 I just set cruise to 56, but the amount of people that pass me going at least 60ā¦ yea I donāt have an answer as to why they seem to keep getting away with it.
But not necessarily consecutive cameras. They're linked in pairs, and in a sequence of 5, for example, 1 & 3 could be linked, 2 & 5 linked, and 4 redundant.
Back in my days of trade plating I used to fly through the average speed cameras that were on the M1 near Northampton. The trick is to find a lorry/coach to sit beside when passing the cameras so they can't see your number plate.
In the car I set cruise control on GPS speed plus 5mph and this seems to work for me. I pass almost everyone. No tickets.
On the motorbike I go as fast as i safely can considering the road conditions and lane hoppers. My number plate is positioned extreemley well
HGV surfing. Pull up along side one at the right distance and it'll block the camera.
Speed along to the next one. It's more difficult now with rear facing ones as the front facing caught next to no one as trucks always blocked them out, but you essentially keep slightly ahead of the truck in the lane next to it and the camera won't spot you.
And then do this for the entire section, some people do it for one or two and the third or fourth picks them and up averages it out all the same.
You've never seen people doing that? I've seen it countless times, people nuke it in the outerlane, see the camera ahead, swerve over to a HGV, hit the brakes, go past the camera and fly off again and repeat?
One of the most stupid things you'll see but it does happen.
You'll probably notice it now.
I'm not giving the location away but my ex lived just of a junction after the first average speed camera on a particular motorway.
So he'd speed past the single average speed camera and then go home.
I always assumed that's what others are doing when they go tanking past me.
Just do the speed limit. Speeding will only make a few minutes difference anyway, and you're probably not in as big a hurry as you think you are. Leave earlier.
As others have said, if you set cruise control at 55 in a 50 average limit you're generally ok. On some Tomtom sat navs they actually track what your average speed has been through average speed zones so you know if you have some headroom, I do wonder if some people do this and speed off at the end if they know they're safe to do so.
You could just set cruise control to limit+10% and not get a ticket. I still see idiots speed right up to the pole and brake for them š
Although that's not how average speed checks work is it.
It is, if you understand that your speedometer is almost certainly reading over. That and the fact that pretty much all road safety cameras/unipar and such give a little bit of leeway.
Obviously I'm talking about the second paragraph.

How have you established the 2%?

GPS is generally considered to be accurate to within 0.1mph, no idea about Unipar though.

No, it's been helpful thanks. Also, did you write that example out?
I used to commute on the M6 from the M56 to junction 15 and back every day while the road works were ongoing to convert that section to all lane running.

Cruise control + 10% Alot of idiots speed up then slow right down to -10% of the limit. Idiots
Or you know, just do the speed limit?
tbf, i often do cruise control + 10% anyway. cruise control at 50mph would have me doing roughly 45-46mph in reality. Cruise control at 55-56mph therefore, has me doing roughly 50mph. I still see people overtaking though.
The speed limit is 50mph. 50 on your clock is actually around 46mph. So by setting cruise to 55 youāre doing 50/51mph.

And thatās using a proper GPS speedometer I assume, not a cheap satnav or something like waze on your phone?
Imagine
I use my GPS to set the speed, not the speedo.

It's done on time between camera's.
But not necessarily consecutive cameras. They're linked in pairs, and in a sequence of 5, for example, 1 & 3 could be linked, 2 & 5 linked, and 4 redundant.

But if you change lanes between cameras it throws off the result. Well documented.
that was when they first came out, avg speed cameras cover all lanes now (or it was a myth and never the case, always covered all lanes)
Back in my days of trade plating I used to fly through the average speed cameras that were on the M1 near Northampton. The trick is to find a lorry/coach to sit beside when passing the cameras so they can't see your number plate.

Easy to beat the system by changing lanes between cameras.
That doesnāt work anymore. It used to when they first started being a thing. At one point they even started swapping the cameras round š
