The RAC said that although the mandate does not apply in Great Britian, it is very likely that most new cars will be affected, because manufacturers are unlikely to modify new vehicle designs for the market here in Britain.
ISA uses a combination of GPS tracking data, satellite navigation, and information on speed limits of that roads that the vehicle is currently on. If the driver is travelling over the speed limit, the system can reduce engine power until the speed drops to the limit.
Itās just the same technology as already fitted on numerous high end cars you can switch between cruise control, speed limiter, or automatic speed limiter.
The auto limiter is the best option for keeping your licence under our joke speed limit and enforcement regime.In which limits can change multiple times within laughably short distances.Or laughably low limits for road conditions like 30 mph on the elevated A 40 London Westway.
Iāve been reading about problems with people trying this speed limiter technology, Although you can turn it off in the menus some drivers have been seeing how it performs when switched on.
Not very well, it would seem, The placement of speed limit signs in certain situations can be very dangerous, as someone found out.
He was on the A45 doing the national speed limit when he passed a turn off that had a lane closed & a 30mph limit, The cars camera saw the 30mph sign & braked quite suddenly to bring the car down to that speed & almost had a car doing 60mph rear end him.
Itās not the cars fault as it was doing what it should but the placement of speed signs in this situation needs looking into.
If the ācar had seenā the sign from further away then might it have slowed down earlier, and more gently?
Is it the positioning of the sign, or how the car is set up?
I see that the sign does not apply to the road the car is on, but would it not have behaved the same if it was on the slip road?
Yes I suppose it could have seen the speed limit sign earlier + itās coupled to GPS, so the car knows the speed limits, Itās just that placement of the 30mph sign that confuses the car as thatās roughly the position the signs are in for the car to read. Some cars are more sensitive than others.
So are temporary speed limits (roadworks) uploaded onto a database which the carās maps access? I really do not know about this stuff. But the car also reads signs at the roadside? Can cars read overheads on m-ways?
No not really, just the ordinary data for roads, Roadworks are a big concern even for Teslaās FSD. Lidar equipped cars fare better in those situations. Yes these cars can read gantry signs as well ass roadside signs.
It was the same car as mine, a 2023 MG ZS EV which are too sensitive, The AEB scares the heck out of my missus when it applies especially if another car approaches the give way sign from a side road a little too fast, the carsā radar/camera thinks it isnāt going to stop & applies the brakes quite harshly with a loud ABS sort of sound as it works by a pump because thereās no vacuum.
I think there is a sub menu somewhere where you can tone down the sensitivity,
Have āthe authoritiesā taken leave of their senses?
This goes against everything they stand for.
The revenue lost on speeding motorists will be colossalā¦(unless you actually believe the prime reason for current type speed cameras is for road safety that is.)
Donāt worry Rob there are enough glitches in the systems to provide plenty of scope for getting nicked in big way when the thing decides that itās in a 50 mph or NSL limit thatās actually a 20 or 30 limit.
Or a throttle input that makes it decide to suddenly cancel it out.
They will probably make more. I have had my new car for 3 weeks. Its generally quite good. But two stand out moments was driving past a quarry on a national speed limit road. The car slowed me to 10mph as it had somehow applied the quarry site speed. It wanted me to do 70 through a 30 close to the motorway near highbridge - cant remember the village. Other than that it kinda works.
Absolutely. TBH I didnāt actually get down to 10 but it would have. I thought I had lost all power, and put my foot accelerator for the 10mph warnings to sound and flash.

ā¦kinda dangerous then eh?
