Aston Martin Speed limits
Discussion
Hello
Does anyone know how Aston Martin or any other manufacturer is going to handle these EU speed limits due in 2 years?

Cruise control.....
No, it is different from cruise control. Speed limiter relies on the driver to use accelerator and brakes as normal but will not allow the car to accelerate over the set speed, although a steep slope will not prevent overspeed however.
Cruise control relies on the car always maintaining a set speed through the computer controling the accelerator, not suitable in busy traffic.
Yes, my DD has a driver operated speed limiter. It is calibrated from 20 mph in 5mph steps.
Have only very rarely used it.
I do use the Cruise Control for the Avg Cam roadworks. Have you been on the M4 roadworks section ?
Seems to go on for about 20 miles. I set the CC at 53 mph, because I know the speedo is 3 mph fast.
I think the point here is that the new regs mean that the speed limiter will be on and dynamically adjusting to speed limits needing to be overridden each time rather than being something that can be set either on an ad hoc or ongoing basis as determined by the owner.
Personally it's not technology I like. My RR has speed limit displayed on dash and manages to get it wrong on a pretty regular basis, Not looking forward to a world in which other drivers blindly drive at a (wrong) speed limit imposed by their vehicle.

That's a valid concern. I would expect existing system like the one in your RR would improve because currently it uses a proprietary system for looking up the speed limit. For this there will likely be a definitive register for all speed limits that national governments are committed to keeping up to date. Your car will have a database downloaded from the internet to look up speed limits based on GPS data. That will need to be kept up to date by connecting to the internet. However it's not hard to think of a scenario where it could go wrong.Here is an example. Recently a 40mph road near where I live was dropped to 30mph. Because 30 is the default in-town speed limit they didn't put up new 30 signs, they just took down the 40 signs. let's say a car has not connected to the internet to update it's database (perhaps the wireless subscription has expired or the phone provider has a problem), the GPS database would say the limit was 40, there would be no signs to contradict it, so a driver who is used to relying on the system will simply drive at 40mph.
So the system is unlikely to be perfect, but the question is whether it will be worse than human drivers who we already know get stuff wrong all the time.
I had heard that new cars would be having speed limit enforcement.
We can already see the real time speed limits displayed on satellite navigators, so therefore connecting that system to a cars ECU, has always been seen as the next step. Governments will soon be talking about loss of revenue from lack of fines, as if they have now become entitled to that revenue stream.
What I did not expect you to describe though, is that the driver can switch off the system.
If they do decide this is necessary, then why permit it to all be turned off. I don't understand the point of having it.

I wonder if it will be as reliable as tyre pressure sensors, emissions lights, sat nav's and all the other electronics manufacturers like to put on cars now, make sure they get part of an MOT test for functionality, and then reap the rewards of fixing deliberately fragile systems?
Just like cam and crank sensors bring on the engine management light because incorrect timing that they are monitoring can affect emissions. Part of the MOT but well over 95% are faulty sensors causing the fault and there is nothing wrong with the emissions or engine timing.
It will be funny when someone gets thrashed in their DB12 by a Cortina on the motorway and they cannot bypass the system without fear of invalidating their insurance or getting nicked.
You may as well just have a black box fitted like a millennial.

These are my thoughts exactly, way too control for my taste.You may as well just have a black box fitted like a millennial.

The logic goes that sometimes you need extra speed to prevent an accident, or safely complete and overtake, and that in such a scenario a hard limit would do more harm than good; hence the override.

Yep knew that, but of course the system would then detect law breaking has occurred, so automatic prosecution becomes possible. No need for speed cameras then.
I can now occasionally ‘enjoy‘ my AM, when safe to do so and no one is around, but it looks as though this pleasure will eventually be ended for us all.

One argument here is that you may want to get a bulb changed at the weekend when you get time and the shops are open but you will do more starts than that during the week!
The big argument currently is that the manufacturers will not allow the aftermarket access to these live telemetry reports, bypassing the "Block Exemption" regulations allowing repairs to be done by independent garages or owners themselves, all on the excuse of security.

And if the EU get the EOBD3 regulations through, if you get a systems fault light come up on your dash, such as an engine, lighting, TPMS or braking fault etc etc, your own car will report you to DVLA that your car is no longer in a proper state to be legally driven, you can then be prosecuted after a certain time if it is not fixed, or after (say) 10 engine starts. This was foreseen by the manufacturers and hence the latest "connected" feature on cars, with the manufacturers arguing that the system will also inform them of the fault so they can get you booked in to fix it.
