2)Think "Well I don't think this is right. I know that I'm capable of driving faster than the sign says, and consider myself to be safe. But never mind, it will soon end, and then I'll be on my way again." Then you have removed the hazard completely, with the added benefit that your slower speed has indirectly given you longer processing and response times.

So it is about conscious processes. And in this situation making conscious decisions that will remove the hazards and result in much safer driving.


Ahh, well, I think you're close to the core of the problem there.

- Setting speed for legal compliance is always a conscious process.

- Setting speed for safety (operating a risk model) is always a subconscoius process in an experienced driver.

- Experienced and responsible drivers have FAR better things to do with limited conscious processing power than to worry about legal compliance.

- Overriding highly valuable subconscious risk assessment is unwise at best and downright dangerous at worst.

Hello Jub Jub,

I don’t know how old you are but, have you ever driven a car above the posted speed limit?


I used to drive as fast as I thought I was safe to. I got three points about 10 years ago for an SP30.

These days it really isn't an issue for me. I've got far more important things to be concerned about than fighting for the right to drive faster than I need to. So I drive to the conditions, and stay within the limit. Of course, the needle strays over occasionally, but generally when I look at the speedo I find that my judgement is keeping me within the limit. I have never been distracted by having to be obsessed with speed.

I've been driving for nearly 20 years. Both indirectly and directly related to my work, and of course as part of my life. Everything from bicycles, bikes, cars, and commercial buses and vehicles up to 7.5t.

OK. Some more component facts.

- The speedo isn't any real help to the process of safe driving. If it doesn't work it makes no difference. That's because drivers MUST continuously judge speed relative to circumstances in order to manage risk. But the speedo measures absolute speed and can tell you nothing about risk.

- The speed limit is always wrong. If it's right for a Porsche, it's wrong for a Transit. If it's right in the dry, it's wrong when it's raining. If it's right when the road is wide, it's wrong when the road narrows. If it's right when the road is busy, it's wrong when the road is empty. If it's right for a novice it may be wrong for an experienced driver. I could go on all night, but you get the idea.

- Few crashes involve speeding vehicles, and many that do involve extraordinary bad behaviour (racing, showing off, drunkenness, stolen vehicles, unlicenced drivers, recklessness and so on). It follows that the proportion of crashes involving 'speeding' and 'otherwise responsible' motorists is pretty tiny. Our best estimate is about 2% of crashes.


Right. So we're down to the bones of it now. Your battle isn't against speed cameras, but speed limits.

You suggest, quite rightly, that in accidents involving speed there are other factors. The factors that you list can be addressed, but not completely, by education, and by removing certain drivers from the road. Without exporing it too deeply, there don't seem to be any more obvious solutions.

You are not going to change speed limits overnight, if ever (and realisitically Paul you know that you are not in with much chance of getting any change). Your chief concern is with safety. So why aren't you campaigning for changing driver attitude within the current conditions, campaigning for more education, campaigning to get the most dangerous and untrainable drivers off the road permanently? Forget the speed limits for now. As I see it, when you can show clearly that driving standards can be improved to a point where it can be suggested that speed limited should be revisited, by implementing the required steps and showing a successful result, then, and only then, will you be taken seriously.

At the moment there is enough evidence on the roads that speed limits are necessary. You need to be able to prove that your alternative is workable. Campaigning against speed cameras is not going to do this.


No, none of the above.

Speed limits are a perfectly reasonable and useful small part of a road safety system. But the modern means of enforcement has promoted speed limits WAY beyond their level of competence.

The utimate objective of the Safe Speed campaign is to restore the policies that gave us the safest roads in the world in the first place. It isn't US who want to wander off into uncharted territory - it's the authorities who have, carelessly and recklessly wandered off.

-agreed
-agreed.

-of course. And an experienced and responsible driver by definition does not need to worry about legal compliance, once he has accepted that it is there and made the decision to follow it. It is only a problem if he refuses to comply.

-Disagree. Unless you are suggesting that risk assessment and response is as easy at 70mph as is is at 40mph, which of course it isn't. This is where your argument starts to fall down, as you move away from generally agreed ideas, and into your own theories.

There is a base-layer requirement for a driving standard and awareness at any speed. Consider this to be a horizontal line on one of your charts. Subconscious risk assessment of these issues is always present. Above this line, speed is proportional to requirement for increased risk assessment, with the added factors that it brings.

This is where another one of Paul's theories comes into play. I can't just find the page relating to it, but I'm sure someone will know where iti is....

Basically, everyone has a comfort speed - a speed at which information is being sent from the various senses to the brain at a level that keeps the brain comfortably occupied. If the 'data rate' is too high then we become stressed, confused and will miss imortant things. If it is too low then we become bored and distracted. I believe I'm correct in saying that the number of accidents involving HGV drivers falling asleep at the wheel, or barrelling into the back of stationary traffic increased fairly dramatically after speed limiters were introduced for instance.

So therefore if the limit is artificially low, then a driver trying to stick to it will become distracted (especially if he's got cruise control), the mind will tend to wander and he becomes a serious hazard.

Personally, in the scenerio I described with the low motorway limit, I'm happy to slow down from my normal cruising speed - its not about journey time for me - but I resent the threat of prosecution if, after slowing down, I happen to drift a couple of mph over the limit because I'm concentrating on the road rather than my speedo. I also don't like being in the danger zone around vehicles driven by drivers who aren't concentrating.

How do you feel about the continuous and conscious effort required to remain within the limit in a lengthy average speed enforcement zone (a'la SPECS)?

I think these mop up more of a driver's thinking and assessment capability than is safe and promote unnecessary anxiety.

Another of Paul's theories. Again, bare bones. Nothing is ever going to be changed by someone's theories. Unless they come to be generally accepted.

Obviously there is great value in discussing individual theories. But unless they are given substance other than, with the greatest respect, a group of people who want to come to the same conclusion as the theorist, there is not going to be progress.

So far, this campaign appears to have done little, in a long time, to gain any acceptance for the theories. This can only mean that there is massive evolutionary progress required (and all credit to someone who can hang in for the amount of time required), or the theories are not strong enough to be accepted.

... speed limits ... are a very useful guideline to a safe speed for a particular road (...), the problem is with the absolute and pedantic enforcement of limits and the exclusion of virtually all other measures.

Most people who join this site are very experienced thinking drivers, who like to pay attention to the real physical hazards on the road, but speed cameras (and just the possibility of them being present) force the drivers attention away from the real hazards and onto monitoring their absolute speed - something which reduces their ability to observe and anticipate the reals hazards, and which makes them feel like they are driving more dangerously than they otherwise would because they are not allowed to drive in a style which they know is safe. The un-spun numbers from the DfT and everywhere else support this opinion.


How is it that an experienced thinking driver is expected to tick all the boxes of awareness and appropriate and driving, but is incapable of/does not have to have an awareness of speed cameras without suddenly losing his driving skills? All of the other hazards can be managed perfectly adequately, but not speed cameras? Unless, of course, he is driving outside of the speed limits. Are you really suggesting that you can manage to drive safely through erratic traffic, past motorway sliproads, under bridges, through traffic lights, and can cope with all of this, but not speed cameras?

It is only a problem if they are driving at a speed which, to use your own words, they are not allowed to. You know full well that you are more than capable of gauging your speed and remaining under the limit without a constant obsession with your speedometer.

The safe driver doesn't normally look at their speedo except when hazard density is low, and doesn't need a speedo at all in order to drive safely - if you go 5mph over the limit because of a slight down slope or a slight over-acceleration it doesn't matter because you know that you can stop before hitting any hazard. Speed cameras, and especially the use of hidden traps force a complete change of driver priority - that slight overrun is now an exceedingly high risk hazard - to the drivers' right to earn a living. The driver therefore has to spend time modulating his speed that he otherwise wouldn't have done. A simple check of the speedo, due to the change in visual focus takes about 1 second from start until re-established concentration outside (see main site), it is far worse when a reduction is speed is demanded by an artifical hazard such as a camera; I know several where the camera is deliberately placed on a steep down slope, so to be safe from the camera the driver has to spend up to 3 or more seconds on the speedo while modulating the brakes - time which is not spent looking elsewhere. It isn't a "constant obsession" with the speedo (except in highly watched areas), but it is significantly more than I think it is safe to spend when my concentration is better spent on the real hazards outside.

... For many however the translation of the "keep to the speed limit" becomes the primary concern, and in complying with it they fail to Concentrate, Observe and Anticipate, and as a result the general standard of driving has fallen. What we want is a relaxation of the pedantic enforcement of speed limits, which will free up the concentration of the thinking driver, and positive encouragement of a more advanced driving style where training doesn't end with the ticked boxes of the initial driving test.


And that's one of the real problems with your ideas. You have accepted that speed limits need to be there, as some people need them. So how do you make some conform, but allow others to do what they like? It doesn't work does it?

It might work in the classroom, where you either have to all go at the pace of the slowest, or stream the groups so that the needs of the slowest and fastest can be catered for separately. But the roads cannot be separated. Of course, people need to be educated that the speed limit is not something to aim for, and anything less than the limit is safe, but we are never going to get there completely, and so they need to stay. And that's just unfortunate for those who would be able to drive faster and still remain less likely to be in an accident than a poor, slow driver.

Is it really such a problem? All it means is that it is going to take you longer to get somewhere. Once you have accepted that the limits are there and moved on from that, a speed camera is absolutely no risk to a good driver.

I am saying that speed limits should be guidelines. Absolute conformance to the guideline is not something that has to be enforced, except in the most dangerous of actions. Speed cameras however do the opposite because they punish the otherwise law abiding for minor transgressions of the absolute limt, while perversely doing nothing at all about the most dangerous outlaw drivers in their unregistered or stolen vehicles. Is this the way that it should be enforced? We want the properly trained traffic police that have all been sacked or reassigned as a direct consequence of the implementation of cameras to be restored, and they can use their experience and judgement to decide what is a safe transgression and what is not - based on what they see at that time.

Using the classroom example - what you are saying is that it is a bit unfortunate, but very correct, that everybody must be forced through threat of loss of licence to go at the pace of the slowest. Drivers should all be treated as if they are the lowest common denominator (as is happening now), and that by implication there should be absolutely no incentive to improve because no matter how good you get you will still be treated as if you are the most stupid child in the class. That is certainly the way the DfT are treating us with their new speed limit guidance based on average speed not the original 85 percentile rule. And that dumming down of drivers is already being seen on the roads. Roads that have been perfectly safe with NSL limits are being reduced to 30mph, and they intend to continue with this.

I also believe (from personal experience - search if you are interested about my entrapment) that the statement "a speed camera is absolutely no risk to a good driver" is naive. If in the ideal world everybody slowed down, then commercial pressures will force the limits and tolerances to be lowered and the traps to be made more sneaky. Many limits are already insanely low with 30mph limits on clear straight roads protecting nothing but fields, and we are getting to the point where limits will be set to the average speed of the most dangerous section, and then extended out for miles either side. As others have pointed out, completing long journeys at artificially low speeds then that little bit longer to get somewhere becomes significant - and concentration levels drift due to lack to stimulation.

Are you seriously telling me that you have never found yourself on a clear motorway (at 68mph of course) suddenly realising that your concentration has badly drifted and that perhaps you need a break - except that the next break is 28 miles away and nearly half an hour more of tedium. There is an easy way to improve the stimulation level - go faster, but obviously you cannot be trusted by Nanny to do this.

Risk assessment and response is usually easier at 70mph than 40mph. You're making the mistake of thinking that speed is an 'input' to the driving process, where in fact it's an 'output' from the driving process. You don't drive at 70mph or so on a motorway because it's permitted. You drive at 70mph or so on a motorway when it is safe to do so because you know it is safe to do so. 'Fast roads' are only fast roads when drivers assess them as being suitable to support that speed. When hazards threaten we slow down. When traffic stops we stop.

The horizontal line is 'max safe speed' according to the conditions. This is the safety line. The speed limit line varies wildly either side of this safety limit. You're suggesting that an arbitrary legal limit (which is always wrong) is more important than an assessment of the conditions. Clearly it isn't.

BANG! Give that man a gold star!

This is why cameras are a bad thing! You're not doing anything wrong or danerous, but you still get nicked for it!

Out of interest, do you live in an area that has a very strong 'speed kills' message? I live in a county that has consistantly lowered limits across the board and (I believe) the only SCP in the UK that has cameras on the motorway (and I'm not talking about the VSL cameras on the M25 and M42).

I'm very satisfied with the progress we're making on causing change. Try comparing the content of Ladyman's recent speech compared with anything that he's ever said before (or anything that Jamison said before him): http://www.safespeed.org.uk/forum/viewtopic.php?t=11244

Try this... We all know that it's important that no one drives too fast. The government defines 'too fast' in terms of the posted speed limit. We (Safe Speed Campaign) define 'too fast' in terms of the conditions. The speed limit is actually no more and no less than a proxy for the desired objective. Official messages are focussed on the proxy and not on the desired behaviour. Since sticking to the speed limi won't keep you safe, that's wrong, wrong, wrong.

I don't have a problem with it at all., because what you describe is only necessary for the driver who is unable to develop simple skills, or is in a battle with the limit. You're still in the mindset of slowing down for speed cameras. If anything they are better, because they are more of an incentive to develop the easily acheivable standard of being able to remain under the speed limit with minimal focus on the speedometer.

Are you musical?

I ask because some people can regulate speed by reference to engine pitch. I can't do that - My ear isn't sufficiently musical.

A simple check of the speedo, due to the change in visual focus takes about 1 second from start until re-established concentration outside (see main site), it is far worse when a reduction is speed is demanded by an artifical hazard such as a camera; I know several where the camera is deliberately placed on a steep down slope, so to be safe from the camera the driver has to spend up to 3 or more seconds on the speedo while modulating the brakes - time which is not spent looking elsewhere. It isn't a "constant obsession" with the speedo (except in highly watched areas), but it is significantly more than I think it is safe to spend when my concentration is better spent on the real hazards outside.


The fundamental flaw in your argument is that you are still aiming for the speed limit. It is clear that people are perfectly capable of learning to drive 'around' the speed limit without having to constantly monitor the speedo. So it follows that it is just as easy to learn to drop your 'natural' speed by a few mph, thus eliminating the risk of being photographed should you rise above it. Or are you suggesting that is is normal for your speed to wander way over the limit?

And so it also follows that if, for example, motorway limits were raised to 80mph, then exactly the same problem would occur, but at 10mph faster. Unless you teach yourself not to aim at the limit.

I am saying that speed limits should be guidelines. Absolute conformance to the guideline is not something that has to be enforced, except in the most dangerous of actions. Speed cameras however do the opposite because they punish the otherwise law abiding for minor transgressions of the absolute limt, while perversely doing nothing at all about the most dangerous outlaw drivers in their unregistered or stolen vehicles. Is this the way that it should be enforced? We want the properly trained traffic police that have all been sacked or reassigned as a direct consequence of the implementation of cameras to be restored, and they can use their experience and judgement to decide what is a safe transgression and what is not - based on what they see at that time.


Speed limits have to be set somewhere, don't they? And so all that remains to be necessary is for people to stop aiming for the limit.

It isn't a case of either or. Focus on other law breaking does not require speed cameras to be removed.

I also believe (from personal experience - search if you are interested about my entrapment) that the statement "a speed camera is absolutely no risk to a good driver" is naive. If in the ideal world everybody slowed down, then commercial pressures will force the limits and tolerances to be lowered and the traps to be made more sneaky. Many limits are already insanely low with 30mph limits on clear straight roads protecting nothing but fields, and we are getting to the point where limits will be set to the average speed of the most dangerous section, and then extended out for miles either side. As others have pointed out, completing long journeys at artificially low speeds then that little bit longer to get somewhere becomes significant - and concentration levels drift due to lack to stimulation.


You're painting a picture now of a country where all speed limits will be below 30mph, and the resultant loss of concentration disastrous. That's not going to happen, and is rather dramatic. I'm yet to see a serious proposal for a blanket reduction of the 70mph limit, for example.

Are you seriously telling me that you have never found yourself on a clear motorway (at 68mph of course) suddenly realising that your concentration has badly drifted and that perhaps you need a break - except that the next break is 28 miles away and nearly half an hour more of tedium. There is an easy way to improve the stimulation level - go faster, but obviously you cannot be trusted by Nanny to do this.


No. I generally open a window. And I don't tend to suddenly realise that I am in need of a break. It is all part of my driving awareness, so I've never been 28 miles away from a desperately needed stop.

I don't think the argument is complex at all. You have admitted that you don't like being made to drive slower than you want to. Anything that comes after that is just reasoning to allow you to be able to drive faster.

I’ve given you the evidence and the reasoning proving how cameras are, at best, useless; at worst, dangerous. You’ve given me the post above. Either you can’t give conclusive logical counter arguments, or you really don’t understand it.

It is true that the great majority of drivers are being made to drive slower than they want (at the cost of time/convenience); however it is also true that the great majority of drivers are being made to drive much slower than needed to remain safe and considerate. Furthermore, it is also true that drivers are being forced to drive below what is considered a reasonable speed hence inducing atypical behaviour, especially at camera sites. It is also true that limits are constantly being lowered (with the threat of so much more), compounding an already anarchic situation. Your admission of wandering over the speed limit will soon become more than just occasional.
Where will all this end? Would you really be happy at being made to drive at 50mph on a clear motorway, especially enforced by cameras?


Oh, you have the 'speed obsessed' thing wrong. It is not us who are speed obsessed, we are obsessed with the policies of those who are the truly speed obsessed.

Ahh, well, I think you're close to the core of the problem there.

- Setting speed for legal compliance is always a conscious process.

- Setting speed for safety (operating a risk model) is always a subconscoius process in an experienced driver.

- Experienced and responsible drivers have FAR better things to do with limited conscious processing power than to worry about legal compliance.

- Overriding highly valuable subconscious risk assessment is unwise at best and downright dangerous at worst.


-agreed
-agreed.

-of course. And an experienced and responsible driver by definition does not need to worry about legal compliance, once he has accepted that it is there and made the decision to follow it. It is only a problem if he refuses to comply.

-Disagree. Unless you are suggesting that risk assessment and response is as easy at 70mph as is is at 40mph, which of course it isn't. This is where your argument starts to fall down, as you move away from generally agreed ideas, and into your own theories.


Risk assessment and response is usually easier at 70mph than 40mph. You're making the mistake of thinking that speed is an 'input' to the driving process, where in fact it's an 'output' from the driving process. You don't drive at 70mph or so on a motorway because it's permitted. You drive at 70mph or so on a motorway when it is safe to do so because you know it is safe to do so. 'Fast roads' are only fast roads when drivers assess them as being suitable to support that speed. When hazards threaten we slow down. When traffic stops we stop.

There is a base-layer requirement for a driving standard and awareness at any speed. Consider this to be a horizontal line on one of your charts. Subconscious risk assessment of these issues is always present. Above this line, speed is proportional to requirement for increased risk assessment, with the added factors that it brings.


The horizontal line is 'max safe speed' according to the conditions. This is the safety line. The speed limit line varies wildly either side of this safety limit. You're suggesting that an arbitrary legal limit (which is always wrong) is more important than an assessment of the conditions. Clearly it isn't.
