mandatory speed limiters to be fitted from 2022?
Discussion
I had heard about this elsewhere with the difference that it isn't to fit speed limiters to cap vehicle speed but rather like the limiter like on my MY18 Kuga where you set it to a speed and it will allow you to override but will bleep at you and you have to use harder than normal throttle pressure .
I use this feature more than the cruise to be honest, it's very useful if you want to ensure you don't get caught by anything.
That said, it's probably only as matter of time, it's all linked to the push for fully autonomous cars, as is adaptive cruise etc

I think what they are aiming towards is automatic control of maximum speed on motorway. The driver assist on most cars can already do this but I think the aim is to be able to send a signal to all cars at some point in the future. First step towards some sort of autoomous motorway mode

2 issues I hold with this:
1. Its widely accepted that the speed limits are what they are still to cater for the braking distances of old cars still on the road and keep emissions down. So its almost ironic that it'll be brand new cars forced to stay at the limit, whilst the old, less capable (in theory) cars that can do whatever speed they like.
2. As older cars will be able to do what ever speed they like, will insurance companies ramp up rates on these "free" cars, forcing people into new, restricted ones?

The infrastructure isn't there yet to fully implement this.
I completely agree... to an extent. I have a Mercedes which reads the speed limits signs from the mirror rather than GPS based. This does also link through to the cruise control on the car and adjusted the speed (can be overridden/turned off, I have it on)I've taken the car the France, Spain and Germany and works flawlessly. Gives you no overtaking signs, speed limits of slip roads and of course the relevant speed limit. In France in particular, it tells you the motorway speed limit is 130, if the wipers are on occasional the sign changes to 130 / 110 when wet, and then then when wipers are on full speed it just says 110 and I'd concur they were right at each given point.
However, in the UK, it's only about 90% accurate:
It's struggles with dirty road signs.
It can't pick up the urban motorway (not smart motorway) speed limits such as the ones on the M4 at London.
It can occasionally read a sign from a parallel street. It is clearly visible to the road I'm on and probably should have been obstructed from sight, but could present a danger. One particular one is on the M1, there is a 30 slip road and if you're in lane one of the M1 it will start braking.
It can't read some temporary road work ones (the ones in bold and long text, plenty of them in Hampshire - must be the contractor).
It occasionally gives me an 80 mph speed limit on one of the M25 gantry's for the 60.
And on one occasion, the cars suddenly started braking when overtaking a roadworks van on the motorway. This was due to him having a 20mph road sign in the back of his van.
The technology works fine in Europe I've found but not the UK. The faults my system has can be avoided if road sign placement was a little better, cleaner, and by making sure the speed limit sign is of the correct size and font.
In time there's no reason it can't work. It just needs a bit of human sense checking and overridding for the time being.
I'm more concerned about any linked autonomous braking, We've already seen numerous reports of Quashqais unexpectedly and severely braking as an example. I don't mind something that tells me when I'm over a limit and requires me to firmly press on the throttle to over come (hell my kuga does that now, albeit I tell it the limit myself) I'm not so comfortable with it suddenly braking as it perceives a new limit where none may be. I see it on my sat nav when I'm on a motorway and under it is a regular B road with a 30 mph limit.

Our 2016 BMW X1 unexpectedly and severely braked when it thought an oncoming truck was going to hit it. I had taken absolutely no avoiding action as I could see the truck was simply following the A road centre line but a little closer to the line than usual.- notentirelyconvinced
This isn't connected to speed limit signs but shows me autonomous features simply will not work. The computer algorithms are not clever enough and will never match the human brain for conjecture.
Who on earth would get into a car and let it drive itself along a winding country road. You'd have a heart attack!

You're falling into the trap of assuming everyone is as attentive to the road as you are. Every day I see people almost hit other vehicles that I saw clear as day from a much worse position than they were in.This isn't connected to speed limit signs but shows me autonomous features simply will not work.

I'll happily pay what ever they want if it means keeping my old unrestricted car.What get's me, is that the German car manufacturers will be hit the hardest by this. If all car's in Europe are restricted to max speed limit, then what is the point in anything with more than 100bhp?
