The gantry signs imply the lane change much earlier than the road markings do, I think that's the problem. There is a similar situation northbound approaching junction 3, the signs imply that lane 1 is for exit only but it's marked as a normal lane for some distance further.

The lane markings change between lanes 2 and 3 at the half mile marker. That's also the point at which the road numbers are written on the lane road surface.

Perhaps a change prior to the 1/2 mile gantry could be a little earlier. Anyone complaining after that truly is a retard. In fact anyone complaining anyway in this scenario is a bit special.

You do realise that his 60mph-65mph indicated is likely 50mph-55mph in reality? In lane 3 of a motorway? So likely driving slower than the lorries.

The signage is poor but surely anyone can see that driving at this speed for this long on that section is unnecessary and an obstruction.

Are you actually stupid or just speaking on a point you know nothing about making yourself look stupid?

If you don`t believe that and wont be told then the answer is YES, yes you are.

My Volvo speedo does not read 10mph too high at any speed but it does read about 11% too high. At 82mph in volvo S60 (and multitudes of other cars) your actual speed is 72mph.

Get in a 10 year old Volvo, then look at the GPS as it moves along and tell me how much the speedo is out. Then try the same in many many cars and you will see similar things to differing results. Modern cars are generally more accurate but mine is a 2001 model.

Perhaps you should educate yourself about a subject before you start making points and proving how little you actually know:

http://www.racq.com.au/cars-and-driving/safety-on-...
http://www.pistonheads.com/gassing/topic.asp?t=110...

Read something on the subject and stop making yourself look stupid.

Article and factual experience states: "So if your true speed is 40mph, your speedo could legally be reading up to 50.25mph but never less than 40mph. Or to put it another way, if your speedo is reading 50mph, you won’t be doing more than 50mph but it’s possible you might actually only be travelling at 40mph"

Turns out you are the one that is "full of st"

OP far less problem you being in lane 3 (aka lane 1 m40) than those I see every morning in lane 4 who really want the m25 but don't move over until almost parallel with the exit slip. Truly stunning demonstrations of impatience shown every day.

Why do people drive a car on motorways at less than 68mph?

In my case it's because I'm in absolutely no hurry and the difference in mpg between 60 and 70+ is pretty significant. Why should I spend money just tp please someone else. If me doing 60 holds you up, leave earlier!
That's quite a bad attitude to have. Surely the same can be said from the other side. I pay good money to go 70mph on the motorway so get off the road if you can't afford to do achieve the speed limit and no doubt keep with the flow of traffic?

Back to the question though I believe it's a case of moving over too soon and at a slow speed. Considering its 4 lanes of motorway traffic now merging technically into 2 a vehicle doing 60 can indeed cause quite a hazard.

We have a similar junction on the M27/A27/A3 junction. If it is light traffic I will stay in lane 1 or 2 until 1/4 mile from the junction.

As others have said the half mile marker represents the point at which the markings change - though I just measured this on street view and its actually 0.8 miles from where the lanes diverge so even the half mile sign gives you nearer a mile to get over. This coincides with my own perception that its better to move over late for this one. The other thing which does my head in about this junction is stubborn refusal to use both L1/L2 by traffic going towards Heathrow, though I seem to recall the junction was remarked in its current layout only a few years ago?

Complete bks

At an indicated 60-65 my speed is 59-64 as confirmed by force measured miles. If your speedometer is that inaccurate, get it fixed, it's illegal.

When do you think he should move over, just out of interest. 1 mile marker, after the half mile marker? last possible second?

Just asking to determine your opinion as to what is right.

I have just proven to you with links why it is not bks.

Try reading them and educate youself. Your car may be accurate, most cars are not. Do some research, don't make yourself look silly.

Good too see you are not just sticking by your guns and can recognose that some speedos are quite innacurate. OP could avoid all this by doing the speed limit.

Personally if I wanted to drive that slow I would try and move over much later, maybe 1/4 of a mile. Not blindly follow the signage that is setup for heavy rush hour traffic.

And yes I think what the OP is doing may well be legal but it just causing an obstruction by driving with little to no regard for the type of road or other road users.

Do the speed limit, check your actual speed on gps and dont get in L3 a mile before the junction. Problem solved.

Yes thats true and the law is an ass in so many ways.

So you think its fine if people drive at 40mph on the motorway just because "its legal, limit is not a target"

Common sense should prevail. Thought this was PH not brake.

With the speedo overreading argument you are aware as all cars are likely to overread there is likely to be little or no difference between cars.

If someone wants to drive at 40 on the m/way, and they are in the correct lane, then it wouldn't bother me. I certainly wouldn't be flashing them. Live and let live.

However they are quite likely to get a fixed penalty notice if they are causing a hazard to other road users and spotted by the police.

Just wow. No more to say on the subject if thats the sort of mentality we are dealing with.

So in summary (from my PoV)

At a genuine 60-65 there is nothing illegal going on most likely. Lane choice is also not illegal and as marked/indicated....

But there does appear to be a consensus that by moving over a little later and maybe speeding up a tad (not talking warp factor 5 here) then the issue most likely goes away?

So..... What do we think SHOULD be done rather than MUST be done?

It really doesn't seem that difficult to me frown

Your 60-65mph shown on the speedo is more likely an actual 50-55mph.

I understand well and am often unimpressed that people would cause an obstruction on a fast section of motorway like this as they can`t manage the speed limit.

These are rather quite shocking statements.

1. There is almost no chance whatosover that the OP's speedo is out by 10 mph. I'd say virtually no chance whatsover. Far from being "likely" to be 5-10 mph out at 60-65 mph, I'd say there is almost no chance whatsoever that such a thing is happening.

2. A fast section of motorway? It's a 70mph section is it not, much like any other section? But it's a section where the m'way splits into 2, so in fact it's section where caution would be wise, and thus it's a slower section, rather than a faster section.

3. Proven? With links on the internet? A link to a thread on pistonheads is proof? Dear god!

I've used various sat-navs in a variety of vehicles over the past 10 years or more, from MGB to HGV to a typical cross section of modern vehicles, and without exception thier speedos have all consistently been within 2-4 mph error at a wide speed range.

I drive different cars all the time and I use a Tom tom when delivering them and I would say the majority of them (mainly Vw, Bmw, Honda but could be anything) are 5-7 mph over reading on the speedo at motorway speeds but quite a few have seen showing more than that, very surprised you don't know that.

Nope you're talking bks because you said it's likely to be 50-55. All the links you provide show that it's not likely to be that far out. It could be, but in my experience of checking this over many years have never found a vehicle that is so far out unless either the equipment is faulty or there have been some other changes not properly resolved, e.g. whhel/ tyre size, diff ratio change, incorrect speedo drive gear as just some examples.

Furtgermore it's you that's looking silly because you're refusing to answer the question that several people have asked now regarding just where you think he should move across.

@ OP get your speedo checked. Your county surveyor or a friendly traffic plod ( increasingly a rare breed) will tell you where you can find a marked measured mile. Go along with a stop watch and time yourself at various constant speeds. Easier still if you have a sat nav with speed display, that won't be far out.

Personally I'd not change across until after the 1/2 mile marker so the lane markings are in place. Depends on prevailing traffic obviously.

Up to you but if that's still an issue a small squeeze on the gas to get nearer 70 isn't going to hurt tbh.

After that consider that the people ranting at you are unthinking s.
