Reduce speed limits to 30mph - petition

The article was correct. Your van is not a car.

As are these others on the subject.

New cars sold since July 2024 have to have "Intelligent Speed Assist", which means speed limiters that set automatically to the current speed limit, based on a combination of cameras seeing the signs and GPS.

you're wrong in the assertion that the Intelligent Speed Assist automatically sets the speed limiter, it doesn't it just flashes and bings & bongs like the back seat driver that it is, it doesn't prevent the driver travelling at any speed they choose to, they can do 29mph in a 30mph zone, or 129 mph in a 30 mph zone, there is nothing restricting the speed of the vehicle, car or van, other than the driver themselves

I have no automation at all in my 2013 car. But I do have a moderately old TomTom satnav (one with a SIM, maybe 10 years old). It's extremely good at knowing the speed limits (not temporary ones on M-ways). It gives me an audible warning if I exceed them. It's not exactly new technology.

The Sat Nav in my car is suppoed to use my phone connection to check for such things - and traffic especially

Adn it has a guarantee that it will keep working for many years

Except that Garmin have decided that that particular product is not out-of support and discontinued and therefore the update facility is no longer operational

Which is certainly not what the adverts said when the car was new (I got it used)
I have to update it manually every year or so
but even then it's speed limits are dodgy at time
and it knows nothing about traffic any more

Mine has a feature to set the maximum speed
and it claims to know the current speed limit via both signs it "sees"
and by the SatNav

but the SatNav is out of date even if I have just updated it and the "sign seeing" function only works some of the time

for a speed limit to be "forced" then the relevant vehicles would need a reliable WWW connection

and that could easily be blocked by "someone" if they just find out where the aerial/sim card is and have some aluminium foil!

ISA doesn't force it. You can always override by a hard press of eth accelerator.

No I'm not.

t doesn't it just flashes and bings & bongs like the back seat driver that it is, it doesn't prevent the driver travelling at any speed they choose to, they can do 29mph in a 30mph zone, or 129 mph in a 30 mph zone, there is nothing restricting the speed of the vehicle, car or van, other than the driver themselves

That varies by manufacturer & model.

Some just beep at you, many will act the same way as most previous ones, by not allowing you to accelerate past that speed without a hard press of the accelerator, and some will actually apply the brakes to stop you going over the set limit (again, can be overriden by a hard press of the accelerator).

But vall of those are officially classed as "speed limiters", even though the first does no more than warn.

ISA doesn't stop the driver going at what ever speed they choose, it has no control over the accelerator at all, you can still speed if you so desire, you don't have to override anything

SOME implementations of ISA work that way.

Citroen and Peugeot work that way. Possibly some others.

Fiat, Ford, Volvo, Renault, Honda, Mercedes, Vauxhall, possibly some others all limit the accelerator.

A quick google shows that Citroen, Ford & Volvo do not automatically, adjust the speed with info from the ISA, even in the Volvo, the driver has to activate the system to react against the accelerator pedal ,it doesn't slow the car automatically there is a lot of click bait B.S/misinformation about ISA, but it does not function automatically, it's just a warning system, with very few cars that will slow or speed the vehicle up, for those capable of such things, the driver must activate the function first

Ford and Volvo would disagree with your Google search. Citroen I agree, and had already said the same in my post above.

With both Ford and Volvo, you can de-link ISA from the physical speed limiter, and have it just warn you with beeps etc, but you have the option of keeping it linked (except on the EX30 model with Volvo).

Google is not a reliable source. It will mislead you if it helps then sell more.

That is how mine seems to work (Honda)
problem is that it is not that simple to set it
fine for a motorway but too complicated if the limits change

and when I tried it it never seemed to work consistently

personally I just find it a lot easier to use the "Intelligent" cruise control

and my brain

Having more of a think about it, I don't think any forced limitation would work in terms of tech and compatibility. A GPS signal forcing your limit to 30 (which can't be over-ridden), whilst possible on certain low speed stretches, could go wrong and you could find yourself limited to 30 on a motorway. It's a recipe for group litigation.

In my experience the only thing that drivers respond to is the threat of a fine and points. So perhaps average speed cameras are the only option. You can't slow down just before them and then speed up again like static cameras. They don't need to be manned. A quick search says that a standard 2 camera setup costs £5000/year to maintain. That seems fairly cheap given that they would still inevitably get some money back in fines. I think that should also be coupled with a public service announcement to tell drivers to use their speed limiters if they have one

On an A road, an average speed camera would be pretty pointless. To average the current 60 speed limit you'd have to be pretty much flat out whenever you could.
Back in my foolish youth I could just about average 50 through mid Wales but only by driving like an utter bell end

Or maybe insurance costs? With all this data sloshing around are we going to see a rise in policies with reduced cost black box/telemetry policies which will snitch on you and increase your premium if you override the limiter/ignore the warning. If that's how they work, I don't know.
