Volvo made a good first move by limiting its new cars to 111.8 mph. Doubt its made any difference to sales.

Next should be to limit all new cars in UK to say 77mph (max motorway limit +10%) Lorries do fine with speed limiters so why not cars. We'd all soon complain if HGVs were passing us at 70+mph.

 

Then make it work like the speed limiters fitted to lots of cars with option to make the speed limit adaptable (from gps/tsr) which also means some kind of nav system is required.

My boss just bought one of these castrated Volvos, Renault are doing the same thing I believe to this 180 kph speed limit.

 

One of the cars on my short list is a Clio RS and maybe it would be good to get one before the law comes in and its long term value with be helped by such ISA laws or we just bight the bullet and go with the flow and get the track car, something like a Caterham, for those times when one want to blow the cobwebs out, and the motorcycle as well I hope.

 

From what I have read these clever car systems will not stop the main accident for us motorcyclist which we are victims off which is a car making a right hand turn out of minor road and the bike, despite having right of way, then T-bones the car who has not "seen" the motorcyclist.

 

I get even fathom how all these systems will fit and work on a motorbike and the cost they would add as a percentage of current buy price.

The Max legal speed in the UK will still be 70 mph for a Renault Clio RS and it will still be the NSL of 60 mph.

 

Plenty roads with 60 mph speed limits were i stick to the speed limit have HGV's or Coaches passing me, even Speed Camera Partnership vans which have a max limit on those roads of 50mph.

George, if memory serves you have played the percentages game of speed camera static and average and, as the stats show, most motorist often cruise over 70 mph but within the 10+2 "tolerance".

 

I would dread to think of the many thousands of hours drivers would spend on the road, the missed delivery slots if drivers, car and truck, had to stick to under 70 mph (GPS with a tolerance of no more than 1% inaccuracy).    

 

Dual carriageways are 70 mph nominal as long as they have a central reservation and long may that continue.

 

As I have said I would rather we implemented a legal OK to drive at 75 mph with a "your F*cking nicked son at say 78 mph, sure well have the tech to do this ie high sampling and accurate GPS.  

 

I level playing field with agreed tech please.

 

I did my time in the Speed Awareness Course when I hit the big 80 mph down Air Balloon hill on the A419, should have broke more and wasted that kenetic energy and added more CO2 to the dying Earth's air mass.

 

Please can we have speed limits like France or even Germany does, it is a point of national shame, and economic efficiency that we do not.

 

Would be happy to have a F1 style fuel flow limiter so the car cannot do less than say 50 mpg.  Would encourage me to change my mark 3 Octy for a more aero efficient mark 4 which for the same hp has a some 6 mph higher top speed as it so aero efficient, 143 compared for 137 mph I recall for the same HP ie 150.   PLus more safety features as standard.

 

@lol-lolIf you remember the threads in this section you might remember that the 10+2 tolerance was and is an England & Wales thing since the Scottish Government allowed Police Scotland to have a period of a pilot scheme and then changed the powers they had.

 

No speed awareness courses in the Scotland but there are towns on Trunk Roads with Average Speed Cameras in the town and 20mph speed limits.

Well, either you're not actually doing 60mph, or the HGVs do not have legal speed limiters which must be set to no more than 56mph. Coaches are allowed to do over 60mph on motorways.

@KenONeill

There are no Motorways North of Perth, and the A9 from Stirling to Perth is not a Motorway.

 

@lol-loland others doing Speed Awareness Courses should be tested on knowledge of the highway code.

 

Coaches of different lengths have different Max Speeds and England & Wales differs on those with Scotland.

A HGV pilot scheme on speed limits was carried out on the A9.

One of the best way to calibrate ones speedo is not follow a truck thru these 50/60 zone as they will be doing, usually, a steady 54 mph on the GPS, at least in England anyways.

 

The Police Commissioner for Bedford police wanted to nick driver and have no tolerance.

 

Skoda speedo not one of the betters one apparently.....  https://www.autoexpress.co.uk/car-news/106674/uk-speed-camera-tolerances-revealed-is-your-cars-speedo-accurate

5% error shown below.

Skoda Kodiaq 2.0 TDI 150 manual 28mph 48mph 57mph 67mph

^^^ 

The above was on the Tyres on those cars at the time of testing, not all drive on OEM size tyres, that might be more of the case when using winter tyres.

 

Hopefully many of us here know what speed the vehicles they are driving are actually at and not sticking to the speedo indication and have frustrated drivers behind them, 

especially those that chose to hog the outside lane as the inside lane carries on passing them.

When did I make either of those statements? (hint, I didn't ;) )

@KenONeillRead your bit on coaches being allowed to do over 60 on Motorways, well some are, and some are not, and they will not be between Stirling & Perth or North of Perth.

Then some HGV's limited to 40 or 50 on parts of the A77 will be exceeding that by quite a bit.

 

But then i know what roads i am on when driving at the speed i am and know what other vehicles are limited to on those roads.

@e-Roottoot I don't claim to know what roads you're on, because you never said!

Please can we have speed limits like France.

 

 

So are you happy to comply with the overall speed limit of 50mph, 80kph on French roads, apart from autoroutes and some dual carriageways?

I have generally found the French speed limits appropriate for the roads they are set for.

 

I find it interesting that they change Autoroutes from 130 to 110 kph in the rain which I think is an idea supported by statistics but it is 130 kph that I like as the 10% seems to apply there too so doing 145 kph, which is 90 mph cruising on their motor better than the UK's poxy 80 mph which one can get done at.

 

Worth reminding travellers that one can get done if one is too quick between toll booths so if one does do a blast of 160 kph plus between the booths then stop just before the booths in the pull over area and wait for a few minutes so ones average speed drops down in to the legal numbers.

 

France makes technical inspection for motorbikes compulsory -  newmobility.news

 

So you are happy doing 50mph on a French arrow-straight wide well paved road which we and the Germans would limit to 60/62mph? The speed is not appropriate for the road and has not been limited for safety reasons.

To clarify, buses and coaches are limited to 60mph on dual carriageways. Coaches under 12M long have a limit of 70mph on motorways, coaches over 12M long are limited to 60mph.

I would probably doing close to 90 kph on such a road but slow right down for the villages.  I find the markings and camber an issue sometimes.

It I is probably I am more relaxed and not in pushing it.

 

difference in motorway speeds France to UK Is significant but UK to Germany is massive.  Spanish motorway better too than UK.

So you would be happy to be doing 90kph when there would be an 80kph limit at most on that road?

Oy yes based on the police all over are using similar doppler/laser speed measuring equipment and cars are manufactured with 10% speedo tolerance and 2% for tyre differentials but I tend to have the 

GPS fired up so with the oft 5% speed error on a Skoda I would have 90 kph on the speedo and 85 kph, at max, on the GPS.

 

Despite France being my company HQ it is more usual that I am on holiday and it is the motorways I want to tank along and part from the tolls I prefer French motorway ie significantly faster averages allowed, less traffic mostly, except for those annoying pinch points like Le Harve.

 

Doing 30k miles plus in normal years in the UK it s so frustrating to cruise around in the 70 mphs, 125 kph, or less.

Then to hop over to Europe, especially Germany, and drive at 200 kph plus and neigh on 145-150 kph in France and Spain on the motorways.

 

I'd be happy with a warning on the dash telling me I've exceeded the limit, but not the car refusing to go if I put my foot down.

AI is definately A, but not necessarily I.

 

At the end of the day if you start to couple this with vision tech, such that the car decides when you can accelrate out of trouble then you're going to find it gets it wrong a lot more than some say. Ditto if the car cuts power mid corner.

 

I'm not one for exceeding speed limits, but I am one for letting the human who could die have the final say.

I wouldn’t like it if the car wouldn’t allow you to accelerate to avoid an accident.
 

I’ve had two incidents in the past when being able to go above the speed limit saved me from an accident.

 

One was a truck deciding to just swerve into my lane (I think the driver nodded off and I had to get clear) and one where one of the wheels came off a car in front.

I've had an example of this too. 35 years later, I can still take you to the stretch of road in question.
