Personally I feel "attentive" driving at 90. Not overly confident, but definitely attentive. Anything over 90 starts to scare me.

I am at an age (59) when I can remember the late fities and the sixties, and the gradual spread of motoring in the UK, and reading some old 'Autocar' magazines I was given recently it is obvious that there were far more fatalities; nearly twice as many as now, with a lot less traffic. Of course there were no national speed limits then, either, just the urban limits of 30 & 40. However strange as it may seem, the traffic was actually a lot slower then, there were few motorways, and most cars were pushed to do more than 80, generally people kept to about 45-50. Nowadays every car can do a 100, (or almost). Cars then had small engines - Minis 900 cc, family cars 1500, only the Jags and others could go fast and even then in not many places. Frankly, speed was not then the main cause of accidents, just as it isn't today, so what has changed ?

(Of course if there was no speed at all there would be no accidents. Perhaps we should all walk !!)

Well, we now have much more commercial traffic, lorries etc. The failure of railway freight is a theme right through this period which includes the Beeching cuts whihc cut railway mileage by over 50%. Currently, commercial vehicles are involved in around 26% of accidents, (and a larger percentage of fatality accidents), but are only around 10-15% of the vehicles registered; food for thought there, maybe.

Roads have improved a hell of a lot. more motorways, better signing, and road junctions etc, and cars themselves are safer - better brakes, handling and so on. And casualties have gone down markedly, with the largest reductions before cash camera patnerships were introduced. Yet we are now stubbornly stuck at around the 3200-3500 mark for deaths.

What has really changed is that far, far, more youngsters drive, and are able to finance the running of their cars. I was a motorcyclist until the age of 32. Yes, I fell off a few times, and it taught me to drive to the conditions. But nowadays, at the age of 17, most youngsters are driving around. This has been accompanied by the dumbing down of the motoring magazines. You have only to look at the style of writing in the magazines of the 1950s compared to today. They were written by educated people for educated people; responsible people, people with families etc, natural law-abiders and people who took care, and were polite to others.

What is urgently needed is a cessation of mechanistic processes which punish people for minor infringements. Nobody, BUT NOBODY can be totally perfect when driving, yet this is what the cash camera partnerships rely on. They are feasting on fallibility. Of course they have generous salaries to pay, and pensions too. Even, dare I say it , incentive payments for maximising revenue from fines.

A concentration of effort on recklessness is what is needed. I think this can only be achieved by police road patrols, not robotic and sinister roadside cameras. People driving recklessly need to be confronted AT THE TIME with their stupidity. Fore some, a warning, for others, the full eight of the law. Of course this will cost more, and frankly, I have to say if any new model of partnership was formed which could draw its cost from the fines imposed for recklessness alone, I would be content, but the current cash camera partnerships disgust me now and always will.


Very well put, I couldn't agree more with your sentiments. I too began driving in the sixties (1960 to be exact) and I remember it as a time of relaxed, enjoyable driving. I wish I could say the same for today's scene.

I totally agree with your point about HGV's, it's hard to know what the solution is but some kind of segregation is needed. It's bad enough on motorways but meeting such vehicles on quiet country roads can be alarming. We segregate railway stock from road traffic, why not HGV's?

Your point about youngsters is well made. They are, in the main, relatively irresponsible (I know, I was one once). It's not really their fault, they need time to gain maturity and responsibility but often refuse to accept their limitations. It would be unfair to label them all this way, there are some good young drivers but the wild (and noisy) minority do them no favours.

Keep up the good work, our society needs mature drivers to counterbalance the endless tide of youth.

Hello,

Not wishing to steal your thunder, but I actually suggested this to my girlfriend (while we were trying to solve the problems of the world, as we do) and I said that wouldn't it be good if I could take a series of courses, tests or whatever to prove to the Police that I was a confident, competent driver at "above average" speed limits.

You know, get awarded with a "+10mph" certificate or percentage-based or something.

So then, when getting flashed by said Gatso, the operator would check plate to name, name to "advanced drivers list" and see that I am legally allowed to exceed speed limits by 10mph.

Not a solution to the Speed Kills mentality problem, but it was just an idea. Nice to see I'm not totally barking up the wrong tree. :)


Actually jola, I made that comment, not TripleS

But remember, with my suggestion, at higher speeds you wouldn't be rocketing past other cars, you'd be passing them at the same relative speed as people do now at 90mph.

On the other hand, if you're saying that even on an empty motorway, 90mph feels close to the limit, I'd just point out that this really does depend a lot on the car, some high performance cars can feel totally stable and welded to the road at well over 100mph, just ask a trafpol :D

And so you should be (attentive at 90mph) not to be so invites disaster. If you feel scared driving faster than 90mph then you shouldn't do so, what would be the point? I would say you have reached your "comfort limit" At least you seem to know and acknowledge your limits, not very common in my experience!

My view on motorway speed limits is that it is primarily speed differentials rather than absolute speeds that are the important factor. I believe that for safety, you need to have neither too much nor too little speed differential between vehicles. My non-scientific estimate of the optimum would be 15mph differential between each lane. It's rare that you encounter people who want to drive slower than 60 mph on motorways, so that would give us 75mph for the middle lane and 90mph for the outer lane.

If we make everyone drive at the same speed, bunching will result. If differentials are too great, the risk of misjudging another vehicle's speed and changing lanes in front of them when they can't stop in time is increased. If we could increase the speed of the slowest vehicles, I therefore believe we could reasonably safely increase the speed of the fastest vehicles, too, to correspondingly more than 90mph.


I'm not sure I agree that differentials would be the problem stevei. Having said that I would say that the abilty to make a number of space/time mental calculations, accurately and in parallel seems to be something very few can do (come to that, making any kind of space/time calculation seems to be beyond some people!) This, I believe, is one of the major causes of accidents. I don't think it is something which could be taught either, it's an abilty we all have (to some degree) but not practised by many.

TripleS, I don't think your idea of an advanced licence (allowing the owner to disregard speed limits) is really practical (however appealing it must be to many). For one thing, even if you had such privileges, how would you exercise them when almost everyone else is travelling much more slowly?


Just the same as I do now. :)

In my view anyone that elects to drive at highish speeds must accept a large measure of responsibility for doing it in a manner that is compatible with the progress of those around him. You need plenty of time and space, and the speed differential should be restrained when in reasonably close proximity to other road users.

It is merely an extension of the duty that applies to all of us when driving, namely that you must behave in a manner than is compatible with the progress of those around you. Defensive driving becomes even more important if you are minded to use high speed and keep it safe for all concerned. Given a properly systematic approach it can be done.

Part of the assessment or testing process by which one would obtain such a 'super licence' would need to check out these aspects of a candidate's style and technique very thoroughly, along with general attitude and driving philosophy.

Despite what some people may think, press on regardless is definitely not my style. You will have references to 'the last of the late brakers' - well I think it nearer the truth to describe me of one of the 'first of the early brakers' if that is any help.

Best wishes all,
Dave.

Speed differential with other vehicles is indeed an important factor, though it depends on who is involved. I tend to study the body language of other vehicles as I catch them up, and I then make a judgement as to how much to trust them. My speed differential is then adjusted to accord with that.

Incidentally I think your 15 mph differential is a bit on the low side perhaps, and I have heard 30 - 40 mph being suggested as the upper limit, though that came from a Traffic Cop so maybe we lesser mortals would find that uncomfortably high. :) I would suggest it is something to be explored cautiously.

Best wishes all,
Dave.

No I didn't!

I think you have goldminer to blame for that bit. :lol:

No problem though, I sometimes have a bit of bother with the quotes.

Best wishes all,
Dave.

I've cocked up the quotes again :) but this time it really is TripleS saying:

Actually I'm very mindful of the problems with young drivers, and I would like to see some better means of helping them to keep out of trouble so far as possible.

It is no use telling them what to do or not do, like always obey the speed limit etc., because they are simply not going to do it. Youngsters will do their own thing whether we like it or not, so in my view we need to work with them, not just lecture them. Even now, I don't take kindly to people lecturing me!

What we should be doing is trying to help them find a style of driving they can enjoy without taking too many risks. It won't work with all of them all the time, but I suspect quite a lot could be done in that respect, and it might yield considerable benefits for all concerned. We should try it.

Best wishes all,
Dave.

My thinking is that you need to be able to accelerate from the speed in one lane to the speed in the next lane reasonably quickly to facilitate lane changing. If you had 30mph differentials, say 60mph inside lane, 90mph middle lane, 120mph outside lane, most cars will take a considerable amount of time to accelerate from 90mph to 120mph, making it hard to insert yourself into the flow of traffic.

Which in turn engeandours lane hogging.

I prefer low differentials. I rarely get more than 15 mph or thereabouts differential, except when there is a spare lane when I suggest a 50 mph differential is fair game (ie the overtaken vehicle is in lane one and the press-on driver in lane 3 for the manouevre).

The elephant racers would think 15mph quite a high differential! :hehe:

I prefer moderate differentials in the range 10mph to 25mph for adjacent lane.

I agree that with L2 buffering 50mph differential would be sane and sensible.

I'd be interested to see the effect on fatality and SI stats of a 110-120mph limit on three lane motorways, with a different focus of attention by the enforcers emphasising the risks associated with discourtesy, carelessness, inattention, intimidation and aggression, also taking into account vehicle and driver capablility.

It might make enforcement a tad more subjective, but I'd have no problem with that. :)


That would be absolutely brilliant for experienced and responsible drivers, but (as I've expressed before) I'm concerned about the effect on the ~5% of drivers who need speed limits most - the inexperienced. This small group haven't developed hazard perception, the ability to look well ahead, or any decent speed sense.

I believe the answer is to test the concept of a higher motorway speed limit with a 50 mile section in the middle of a long route to provide a test with control group.


I don't necessarily believe that we need a huge deal of experience to develop hazard perception and COAST, simply to learn from the experience we gain. But this could tie in well with a subsequent test, about 2 years after the original, where the new driver must be able to display the ability to perceive hazards and display COAST to an adequate level to release him to the full freedom of the motorway (perhaps initially limited by law to 70/80mph).


Germany - or some of the Fed states - operate this system - P plates for 3 years probation before they are allowed to drive at higher speeds. Should point out as Mad Cats have in past - higher insurance is paid to drive above 130 kph as well.

Also - myth that anything goes as well - there are CCTV cameras and anything really silly is prosecuted.

However - would agree most experienced drivers can handle 80 -90 mph and most would settle for this as 85th percentile as they tend to do on those German motorways anyway. Bit of an urban myth that Turno Rolfs are driving above 150 mph all the tiime. :wink: We've never noticed it anyway :yikes:
