Speedos on older cars were often the full 10% out but modern cars are usually much more accurate, often varying only by tyre tread wear and marginal differences between the various tyre homologations for a particular model.
In your circumstances, I'd stick to 78.

It really irritates me when the police drive along the motorway at 65 (deliberately, I'm sure) and nobody will overtake them. Very effective rolling roadblocks they make too. I'll breeze past with 80 showing to enjoy miles of empty motorway ahead, and they never even look twice. I wouldn't do it at 90 though.
ISTRC from sat nav that the Mondeo's 80 mph is in fact about 74 mph.
Cheers

Nobody here can tell you 100% for sure but imo if you were doing an indicated 23mph (so probably 22mph true) in a 20mph limit area you probably are OK. Not all forces follow NPCC guidelines on speeding enforcement though.

How to work out your true speed? Get a passenger to count the number of 1/10 km white posts you pass in five minutes at a given indiated speed. You need to work to keep it constant while still concentrating, so you need an empty motorway. Especially soon after passing your test.
The number turns into speed as below.

92 -- 69

Or borrow a GPS unit and compare the GPS speed to your speedo. Drive at a real 77 mph and you'll be fine in a 70 limit.

I was flashed by a camera several years back in a car with a digital speedo. I didn't see the camera until the flash looked down and was doing 83mph. When the ticket came it said the same speed. On another note- I recall being a little shocked as it was a forward facing truvelo which blinded me for several seconds which I felt was a bit dangerous. I didn't think it was worth complaining as I was in the wrong after all!

no, but bin caught doing 90, tho'. 3 points and £60.

Of course, next time you'll go on your motorbike and be immune from persecution!!

"should I be ok if I constantly maintain an 85 mph indicated speed"
Not on the M4 in South Wales - cameras on bridges around Bridgend are a common sight.

Telling the Policeman who stops you that you checked on a motoring forum and they said it was OK wouldnt help you.
I think you know the answer yourself to be honest.
Different Police Forces will have their own set of standards as laid down by their Chief Constable.
Why not just stay inside the limit and have a less stressful journey.
One Chief famously said that doing 31mph in a 30 limit is an offence and would be prosecuted.

I know that the people who advise us earnestly that sticking to the 'speed limit' will keep us relaxed and out of trouble, with huge smug excrement-eating grins on our faces, mean well and think they are doing it for our sake.
I wonder though if they realise how incredibly irritating they are being. Don't we get enough of this carp from the authorities and so on?

They're like robots aren't they? This government must love them - they don't dare to think for themselves and take justified risks. All things considered I'm not surprised this country's persecuting everyone who dares to disobey Nanny.

Change your plan, join us, and find us no longer irritating.
I hope that you would agree that OP, with his limited experience, would be best off sticking to the speed limit. There's a reason why we all (well done if you didn't - I did) pranged a car within the first year or so of driving.

If you decide to check your speedo using a GPS, remember to do the check on a level stretch of road. A standard GPS measures speed over the ground, but doesn't take the effect of hills, tailwinds or any other factor into account.
Having done this calibration exercise, surely it would make sense to drive below - not at - the indicated speed that gives a true 70mph, just in case you had a lapse in concentration and slipped over the limit?

Yes it would be if prosecution was likely for 71mph but as we all know it is not!

"tailwinds"
Shurely not?

If lapses of concentration are your thing, would it not be more prudent to stay in bed? That way you won't be endangering others on the road.

Whilst I can see the point about altitudinal changes, surely a tailwind would only manifest itself as an increase in ground speed?!
|
|
A tailwind would only make a difference if the driven wheels left the ground, at which point you may not be spending much time checking the speedo. That's the good thing about flying - no speed cameras, and you can go at 250 kts in VFR if you wish.

10% plus 2 was devised many years ago mostly for when you were stopped by a police car. Nips are now being issued for 32, 43, 54, 65, and 76 miles per hour. Speeding is speeding 31 is an offence and the kit these days can measure that accurately. Visit Pepipoo.co.uk and read. Regards Peter

I don't want to be a bore but if you rely on your license and can only take two convictions then I suggest you make sure you are well within the limit.
Remember this law is there because you, as a new driver, do not have years of driving experience behind you.
I live near Glasgow and regularly comute to my brothers near Cambridge. I used to see how fast i could do it in but in doing so I was taking unneccesary risks.
This year I got a new car with cruise control. I set this at a GPS speed of (I think) 76mph and over the course of the journey I possibly was maybe an hour at the most longer. But I arrived refreshed and, more importantly, I did not slow down for speed cameras, traffic patrols as I was pretty confident I would not get done for doing this speed. I did not need to get there any earlier.
Some people have a couple of pints and are willing to get behind the wheel, others won't. No one knows exactly when they are on the limit or just over it.
However, the day they are over the limit and get caught and face losing their license, is when all the regrets come in and the realisation that they didn't need that extra pint, or in your case, the extra 15mins or whatever you saved.
Maybe I am just getting older or maybe I am just wiser and realise that if I lose my license, I could lose a helluva lot more as well.

Aside from all the politics, I'd strongly advise the same as most. Those first 2 years are probationary - if you get 6 points that licence is gone forever. After 2 years you'd have to be driving horrendously to get your licence permanently revoked. You're FAR more likely to be pulled in an urban area, so stick religiously to 30 and 40mph limits. Motorways and dual-carriageways are more flexible, but if you see PC Plod parked up with a radar, don't do what I did the other day and blast past at 85! (still waiting for my ticket!)
|
Of course I don't think people should get fines or points on their licences. I have managed to keep these within bounds so far on mine by being normally prudent and observant, just as I have generally avoided running up trees or into other vehicles by the same means.
It isn't reckless or insouciant behaviour that I seem to favour. It is fluid behaviour. The thing that gets on my nerves about this conservative, better-safe-than-sorry approach to, damn it, speed limits - not reckless or careless or aggressive driving - is that it tends to slow all traffic down by 10mph in the short term and impose a rigid, doleful, processional quality on us all. Among other things this is bound to distract people from the task of driving by seeming to make concentration less necessary.
By analogy, you could say that it makes the traffic more viscous, turning it from brake fluid to thick treacle.
It's an aesthetic thing. People drive better if they are properly awake. There's nothing wrong with working hard to make progress provided the real rules are observed.

Switch off the climate the control, open the windows, and get a storm of fresh air to wake you up

Like not going so fast that cyclists and pedestrians stay off the roads because it's all gotten too dangerous?
|
and pedestrians stay off the roads....
Pedestrians shouldn't be on the road in the first place, unless they happen to be crossing from one side of the pavement to the other.
|
>> and pedestrians stay off the roads....
Thats good, i dont drive on thier pavement, and they dont walk in my road.

'Gotten', NW? I always thought you were one of us, linguistically at least.
And of course you miss my point about being properly awake. It isn't a question of breathing deep and admiring the sky. It's a question of giving conscious intellectual attention to what you are doing at all times.
|

'Gotten' is correct English, is just that its fallen out of common use in the UK, but been preserved in the US.

Er, correct me if I am wrong Aprilia but I thought the address of this forum was .uk....
I only snipe at people's spelling and grammar if they have annoyed me, but this creeping US stuff gets on my nerves, train station, pah!

This is completely false.
What actually happens is that if you get 6 points, your full license is revoked.
This is NOT permanant. It is NOT gone for ever. It is NOT a ban. You can re-apply for a provisional immediatly, and retake your practical driving test whenever you wish.
It is possible, test centres permitting, to be back on the road less than a month after having your license revoked under the New Drivers legislation.
Albeit with 6 points already on the license.
|
This is completely false.
I think you might've misinterpreted what I was trying to say. In order to regain your status as a driver, you'd need to pass theory and practical tests all over again. Hence, THAT licence is gone forever, you'll need to earn another one before you can go out and drive. Bearing in mind the number of bad habits I picked up in my first 2 years behind the wheel, I wouldn't fancy anyone's chances of passing 1st time without some refresher lessons. All unnecessary time and expense, and MUCH more sensible to stay on the right side of the law and keep your original licence rather than having to go out and pass your tests again.

"If you decide to check your speedo using a GPS, remember to do the check on a level stretch of road. A standard GPS measures speed over the ground, but doesn't take the effect of hills, tailwinds or any other factor into account."
Of course it takes tailwinds into account. the speed is the speed tailwinds or not. And height variation makes not a jot of diffrence. The GP unit is measuring distance/time so is totaly accurate on a straight. Its not on bends as it measures things in straight lines and so "cuts corners"

That's very strange you getting blinded by a Truvelo camera as they have a non-visible infra red flash.

The flash on Truvelo devices, at least the earlyish ones, may have been subdued compared to same generation Gatsos but it was not invisible.
I was caught by one in Harlestone Northants c2002. The flash was visible enough for me to spend a fortnight or so on NIP alert but never heard anything. In those days they still used film so presumably it's run out.
It would have been a fair cop too.
