Speed limiters on all cars - barchettaman
What a cracking idea - linked to GPS technology to automatically reduce the speed of the car to the immediate prevailing limit.
Advantages:
lower fuel consumption
less points on licenses
probably less accidents/road deaths
less chance of being slammed into at 90mph by someone coming the other way.

It wouldn´t be too expensive, as the cost of producing 30,000,000 would drive the prices down.
Obviously you could raise the motorway limit to 85, safe in the knowledge that noone could exceed it.
There would be small portable units available for shortterm hire at the ferry ports for foreign vehicles.

Complete tosh. And the Government wouldn't like it as according to your logic there wouldn't be any speeding tickets issued...
Speed limiters on all cars - cjehuk
Think it would end up with much the same situation as people currently complain about with Lorries i.e. small speed differentials making overtaking difficult and changing lanes hazardous as everyone tries to 'maintain' progress and not allow anyone else in. Plus you then may as well kill off any car that has more than 1.4 engine even in a large car as the power excess would be pointless. Good environmentally, bad for the industries.
Speed limiters on all cars - David Horn
No, it wouldn't kill off performance cars, it'd just stop them being driven at stupid speeds on motorways and a-roads. Still do 0-60 in 4 seconds etc.
Speed limiters on all cars - Lud
Barmy idea, absolutely lethal.

Something like that may well happen eventually. But people who like cars shouldn't encourage it. They will end up like the intellectual Iranians who thought the Shah vulgar and pro-American (as well as a bit of a tyrant) and so did what they could to bring the regime down.

Are they happy with what they've got now? No they aren't.
Speed limiters on all cars - barchettaman
Think of the upside though. We´d all save a shedload of money on fuel, and there would be less of Clarkson screamin ´more power´ and powersliding Nobles round airfields. Which can only be a good thing.
Obviously track days would be exempt from the speed limits - those with a speed bent could just get a weekly blast round Snetterton, then resume their steady, sedate progress the rest of the time.
Less road deaths (probably), the end of speed camera ´partnerships´, and we could spend the money saved on petrol on, for example, red wine. Another good thing.

>>Less road deaths (probably)<<

There you go again - probably. Any evidence? I thought for one recent year, speed accounted for 7% of accidents. That's an awful lot of other causes.

>>and we could spend the money saved on petrol on, for example, red wine. Another good thing.<<

No thanks - I'd rather drink the petrol! ;-)
Speed limiters on all cars - Westpig
Superb idea?

If i tried an overtake i could sit in the outside/offside lane all day, instead of nipping past safely

then there's the 'malfunction' because some clown centrally sets the limit incorrectly and we're all doing 50mph instead of the permitted 70mph

there'd be considerably more deaths and accidents purely because of the boredom factor (Paul Smith on safespeed.org explains it better than i could)

do the powers that be wish us to turn into robots or will they accept one day that we are individuals, that often do things differently.... within guidelines/ laws...........NOT strict rules set at a very low threshold
Speed limiters on all cars - IanJohnson
The reality - those of us who obey the rules will drive around in the limited cars.

Those who don't will disconnect them and drive as they do now - untaxed, uninsured, unlicenced, and UNLIMITED.

It will do for road safety what the ban on handguns did for gun crime - absolutely nothing

Speed limiters on all cars - Red Baron
The electronics would be prohibitively expensive.

It would only be cheap if the electronics worked perfectly all of the time...which it does not. There will have to be two such devices in each car that can communicate with each other through feedback loops and hardware checks such that one channel or lane takes over if the other is sending erroneous signals.

Even then you only need the first mishap where instead of limiting the speed, the device accelerates the car which in turn results in a fatality. Disastrous.
Speed limiters on all cars - AlanGowdy
I hesitate to contribute to this thread as I was rounded upon when I suggested as much a year or two back... Oh well, here goes...

At some point in the not-too-distant future all new cars will be fitted with tamper-proof GPS-controlled speed limiters. There are obvious conclusions to be drawn about such things as rocketing values of older cars not fitted with limiters and cars being designed for neck-straining acceleration up to the legal speed limit. These considerations and any others you can think of will not stop the faceless bureaucrats using the technology as and when they consider it proven and politically acceptable. If you believe otherwise you are deluding yourself. Sorry.

Don't shoot me, I'm only the hapless messenger.

Speed limiters on all cars - NowWheels
I think that there are two options for this. One is to have a satellite-or-similar-based system which enforces the limit on all roads. Expensive, but will probably soon be feasible.

The other is a more modest device, which simply limits the top speed to whatever is the highest limit on that country's roads. Much simpler, much cheaper, and uses already-proven technology (as deployed in HGVs).

My guess is that the second type is not far off, and that the first will follow about a decade later after most of the bugs have been ironed out.

Whatever the merits or demerits of the GPS-based limiters (and I'm sure there will be plenty of problems), the debate will be curtailed, because the 70mph limiters will have met with so many howls of anguish from roadhogs who claim that their freedom is curtailed when their car cannot achieve an illegal speed. That illogicality will be repeated so loudly by the petrolheads and the makers of fast cars that by the time the system is implemented, its opponents will be perceived as discredited flat-earthers.

If you can find it NW, have a look at Rudyard Kipling's slightly nasty and silly motoring story 'The Village that Voted the Earth was Flat' (1917 I think). I am sure you will disapprove, as the whole thing is a practical joke by rich motorists annoyed by speeding fines. He wrote another, similarly robust and unkind, pro-motorist (but rather anti-car in this case) story called Steam Tactics (1904). Same basic theme.
Speed limiters on all cars - barchettaman
We obviously can´t be trusted to keep to the speed limits - hence the 1000s of speed cameras out there.

Police would suddenly be able to concentrate on real crime, in the knowledge that the speeding motorist is a thing of the past.

Why are people against something that merely enforces exisiting legislation? Personally, I wouldn´t use a knife on a plane, I don´t carry one around, but I´m glad scanners and checks are there to prevent people doing so - again, technology merely enforcing existing legislation.

Or are people so desperate to break the law these days?

Actually, I usually quite like Kipling. He's long been out of fashion, but many people don't spot his heavy use of irony, and I have always like Orwell's assessment of him as a "good bad poet ". He has a kanck of saying things that make everyone uncomfortable, which I admire.

In that vein (and starying a little off-topic), there were two interesting articles in this weekend's motoring telegraph on climate change. I won't post the links here, but I do enjoy reading articles of whatever persuasion in places I don't expect to find them.

If only to repeat and add to my point on the Dangerous driving pt2 thread:

Speed does not kill, it is hitting something that kills and if averarge speeds are ever lowered the congestion will increase and congestion is a causal factor in RTAs. I know, lets have clever electronic devices that dont allow the car to start if the surounding roads are too busy!

Efforts need to be made to allow swift passge without increasing risk this having the double benefit of reducing journey times and reducing congestion.

>>I think you'll find Traffic Sections are being reduced severely>>

This is very true and has been for several years, as two of my one time traffic cop mates will testify. Much of this cutback was due to the spread of speed cameras, which don't address many of the serious problems on our roads such as poor or dangerous driving.

Those who would wish to impose speed limiters and more sinister methods of curtailing/rationing our activities are control feaks, whether in reality or who would love to be able to impose such sanctions. It's not just government, local councils are becoming increasingly active in this area as, for instance, many motorists will confirm.

As pointed out in other postings above, this country is increasingly fostering a totalitarian regime yet, for some unfathomable reason, the majority of the population seems completely oblivious or immune to the fact.

The "free" market will bring this in, not the government. Fancy cheaper motoring insurance if you have this fitted?

Actually I'd favour this if it allowed a margin for error and gave you a get out of trouble cushion, say 80mph on the 70 mph motorway with a time limit (say 20 seconds?), after which you get fined. Driving all day at 150 on a track would still be ok of course.
Speed limiters on all cars - mjm
I have a speed limiter built in. It reacts to all speed limits in all countries automatically. It will also react quickly to current prevailing road/traffic/weather conditions. Most of its sensors are duplicated and the central processor is extremely fast in operation.

It also has the ability to control the rate of acceleration, interior temperature, radio, windows, seat position etc, all in one unit.

It's called a brain. I go nowhere without it.

Shame that so many cars out there appear to be piloted by drivers who are missing that optional extra!

I agree though, none of us drive at our cars maximum speed all the time, if ever. Therefore we are already limiting ourselves to what we believe to be safe and reasonable. If we all got a bit better at that and *were* able to adjust to conditions (many don't seem to be able to) then electronic speed limiters would never need happen.

If only life worked that way! ;)
Speed limiters on all cars - school boy
You would have to have an off switch for track days, but then people would know where it is and would have it off constantly. There would be no speed cameras to catch them and obviously no police so it would defeat the point, plus it would be dangerous. The best idea that you can and never will beat is the police and officers with descretion, they would then earn more respect and not persuse pointless issues like speeding on the motorway at night, i.e 90mph on an empty, lit motorway at 3am.
Speed limiters on all cars - Adam {P}
The idea schoolboy, is that it would detect when you're not on a public road - therefore, no need for an off switch.

I know! Given the cock up they made of the MOT system, I'm almost looking forward to this.
Speed limiters on all cars - school boy
Well, then people will find the areal and block the signal. Just look at the trouble people go to detect/block speed cameras.
Speed limiters on all cars - TheOilBurner
Simple solution to this, if the device has been disabled somehow, it wouldn't allow the car to be driven anywhere.

Yeah, people will probably much about with the wiring etc to by-pass it, but the fines for getting caught would be very high.

Easy to catch you to, any car breaking the speed limit with such a device fitted would be immediate proof of interference with the device.

It would probably be checked as part of the MoT and police roadside checks.

I doubt many people would bother going to the trouble of disabling the limiter, they'd just learn to live with it.

Speed limiters on all cars - Armitage Shanks {p}
Oil Burner. By definition, if the device has been disabled it has no ability to control the car - disabled means does not work or have an effect!
Speed limiters on all cars - TheOilBurner
Yep, but I wasn't making myself clear I guess, if the ECU of the car *requires* the speed limiter to be available and functioning, then it wouldn't simply be a matter of disabling the speed limiter, you would have to de-couple it from the ECU (i.e re-program or replace the ECU) to make the car work. I doubt manufactuers would want to implement this feature, but governments may mandate it, I would expect.
Speed limiters on all cars - TheOilBurner
Oh for an edit button..

I also would expect that eventually, for sake of cost and to prevent interference, the speed limiter would be built into the ECU. You wouldn't be able to remove it or disable it no matter how hard you tried. You could still attack the aerial, but no signal from the aerial could mean the car would stick to an enforced 40mph maximum until the signal is restored, for instance.

Jeez, what am I saying? I'm just giving the pen-pushers in Whitehall all the wrong ideas!! :-(
Speed limiters on all cars - Adam {P}

If an engine ECU can be re-mapped, chipped or whatever some clever clogs will come up with a way of telling it that it has a speed limiter in place but of also nullyfying its effect. If it is a computer it will either break, its behavious can be modified or it can be hacked!

Eventually such 'smart' speed limiters might become the norm (The actual MCC Smart itself has a limiter, at 84 mph, I believe) but by then cars might virtually drive themselves anyway - something that has been predicted for decades without coming to anything more that a few demonstration vehicles on test tracks. But now the technological know how exists. What I could foresee is a system where the driver still steers the car and controls the speed, but is over-ridden if he/she tries anything outside the set parameters.

Deep breath... any speed limiter would be integral to the engine management system so not physically accessible and designed to flag up any tampering when next interrogated during servicing or MOTs. "They" could compel dealers to report any such tampering by means of imposing heavy fines for non-compliance (this might also benefit insurance companies by detecting undeclared chipping).

I can't imagine any system would be designed that would slam on the brakes when detecting a limit change, rather it would apply a reasonable rate of deceleration just as any sensible driver does now. As is currently the case, a following driver would be responsible for maintaining safe separation between his car and the one in front, so if the one in front is gradually slowing to obey its limiter there would be no excuse for not reacting accordingly. It's no different from what happens in today's world of free choice.

God - I'm almost enjoying this - the medication must be wearing off.

Won't say I never speed- once did 90 up a motorway to get out of a coppers way. Blue lights behind, 2 lanes, left lane full of people queing for the slip road. Got a friendly wave from the passenger plod as they passed once it was clear for me to pull over to lane 1.
Speed limiters on all cars - IanJohnson
1st problem with all this is what happens when it fails - and 2 parallel systems (Duplex) do not work in safety critical situations as the two do not know which is giving the wrong output so BOTH have to shut down - the answer is three parallel systems which assume that the odd one out is wrong and it gets shut down then reverting to Duplex - far more complex overall.

2nd problem - if it just removes power when moving from an NSL into a 30 ... Have you seen how far you can coast when you are doing 70! So to work the system MUST be able to apply the brakes.

3rd problem - there will be a market in unlimited ECUs. Cannot imagine the US or France accepting them! Anyone not wanting to comply gets a second ECU (growth market for Ebay) and swops it back for MOT tests and the like - after all the BiB will not be qualified to check if the car has been modified so will ask for it to be taken to a test station and on the way you swop the box over!

4th Problem - Any tunnel will become a racetrack when quiet as there is no GPS signal - are those long straight ones under the Thames at Dartford ever quiet?

5th Problem - what about fog/snow/ice - I must have been doing a safe speed officer because the limiter was allowing me to do it ! ! ! !

The reality - they do not need to do it this way - for those who notice the traffic master blue monitors around the country - they record vehicle speed between two points by number plate recognition and coule be used as a national specs system - far cheaper and will catch any car whether fitted with a limiter or not!

Driving a car is not a 'freedom' . A driving licence isn't a right, you need to pass a test to obtain one and it can be taken away . What is a freedom is the right to travel.
