UK to adopt speed limiting tech: do you support it?

I used to sell Trucks for a living (which have a mandatory top speed limiter always in place) and when demonstrating to a driver when I showed them the OPTIONAL driver variable speed limiter their first reaction was " I can't accept a limiter, my job is hard enough already and I need to go as fast as possible !
However when I spoke to the drivers a month after they had been driving the vehicle….THEY LOVED IT. A comment often made was they saw it as a protection for their licence…it made the truck so much easier to drive.
Between brain dead car drivers not allowing enough space and cutting in, and kamikaze pedestrians with a death wish and not forgetting the "Ninja" cyclists who insist on putting themselves in the blind spot of HGVs on the inside, having a driver variable speed limiter helped the drivers adapt to ever changing road speed limits, whilst remaining legal.
I think the sensible operating sequence helped greatly, the driver would drive the vehicle to the speed limit and press a button and then depress the throttle pedal to the floor using it as a foot rest, however the throttle still allowed variable control by slowing. If the road conditions changed and the limit was too fast the driver lifts his foot on the throttle which allows the vehicle to slow down as normal, or he would brake if more urgent slowing was required. When the road was clear the driver would again apply full throttle and the truck would accelerate back up to the original speed limit set, when the speed limit changed the driver would brake or accelerate the truck up to that speed and again reselect the new limit and carry on…it's so easy.
Having sold hundreds of trucks and discussed it with many drivers who used the system on a daily basis, the number of drivers who said they needed to accelerate rapidly to get out of trouble was limited to a couple of instances. When discussed with the drivers they admitted prior better road reading by themselves would have eliminated even those, as it was they simply pressed the variable speed limiter button and accelerated out of the problem…not hard is it ?
On todays congested roads a sensible system which can sense a vehicle speed and send a signal to a vehicles ECU (black box) will help maintain a more even traffic flow which in itself reduce possible accident spots.
It's different, moan if you like but there are no obvious downsides that cannot be technically sorted…it's the future.

I was done for speeding about 2 years ago on a dual carriageway and had to attend a speed awareness course. Much to my surprise I enjoyed it and found it informative and interesting. So when I came out I thought to myself “that’s it, no more speeding” and I have stuck to speed limits ever since. Initially it seemed a little irksome, but now I am used to it I cannot see why I bothered to blast away just to save a minute or two. Even on a long journey it makes very little difference and you arrive much more relaxed. I use cruise control a lot and it saves me worrying about any speed traps. What is the point of rushing around all the time?

One interesting but possibly not yet widely known factor is that, with so-called smart motorways, speed limits are reduced at certain times of the day to prevent excessive vehicle emissions. Apparently, this is quite common where motorways run through densely populated areas.

If every single vehicle in the UK was mandated to follow speed limits on the same day, this system might work. If not, speed-limited vehicles will become mobile chicanes for those vehicles which aren’t, causing endless tailgating, road rage, rear-end collisions and sharp braking which (in a long enough convoy of vehicles) causes traffic jams even on motorways. Speeds of 90mph seem to be common among the drivers of German saloons on motorways, and a car limited to 70 will very quickly become a hazard to itself and to others.

It would be lovely to live in a world where everyone respects everyone else’s space and driving speed, but that’s not human nature. Mass flouting of motorway speed limits (which were arbitrarily set half a century ago as a temporary measure during heavy fog in an age of drum brakes) won’t be solved by this act of bureaucracy.

Why make cars , Lorries, Vans, Motor Cycles that can travel at speeds above the speed limits ? The lunatics on our congested roads and motorways that are speeding and race one another in powerful cars and those in smaller high speed cars spoil it for rest of the law abiding public.
Bring on the highbred vehicles limited to the speed limit that the vehicle is travelling on ie 20 mph in Towns and by Schools 50 mph on Ordinary Roads and 60 mph on Motorways.
Technology can help us stop the appalling driving now being experienced by law abiding drivers , we see every day drivers breaking the law , no seat belts being worn, aggressive drivers travelling much to close to other drivers, drivers on their telephones while driving, and drivers staying in the central lane of the motorway when the nearside lane is empty , one could go on and on.

Older drivers must undergo a full medical and mental assessment when applying for a driving licence at 70 years of age.

We are not ready for enforced speed limiters. Almost all record you as travelling faster than you are actually going. Also there are too many instances of speed limits in places where they are not needed; how many times have you been limited to 50mph or 40mph in roadworks only to discover that there are no roadworks…just a pile of traffic cones at the side of the road.

There is so much bad and dangerous driving in the south east of the Uk, particular around London. Cyclists and motorcyclists being the worst affected. This will not be solved by speed limiters. Speed limiters are easy and can be used to argue the government is doing something about road dangers and keep the cost away from the public purse. The reality is they’ve cut police patrols and driver training. roads and motorways are almost entirely policed by speed cameras and people are driving dangerously, often below the speed limit. Where’s the campaign to observe the keep left rules on montorways? Where’s the patrol car pulling people over for weaving or understating? Let’s focus on safety rather than making vehicles more expensive

I see that manoeuvres such as overtaking ‘shouldn’t’ be affected… this is my only concern. I often see drivers who appear to go faster than their level of competence allows them to do safely… and in general, on motorways, dual carriageways etc. there is no good reason to exceed the limits. However, on single lane roads you need to be able to pass quickly, to spend as little time as possible on the ‘wrong’ side of the road… so, for a brief moment when you need quick acceleration, I think exceeding the limit should be permitted. I’m not sure how the technical side of this is to be achieved.
It would be no bad thing if average speeds over a journey were monitored, so that insane ‘white van men’ who appear to think they are immortal, could be reined in a bit. Some of them consistently exceed the limits.

I don’t support the mandatory limit. This will make most road users less productive, less efficient, and put up costs.
The most useful way to reduce danger to the public would be to limit the speed of the rogue driver, without impacting everyone, and the economy. Where I live, it is now an everyday occurrence for some idiot to overtake a car on a speed limited street (20mph nearly everywhere) by passing the wrong side of a bollard. This is the guy to constrain.
