MG4 EV speed limit issue

[riskybiscuit]

Maybe go into settings and set things for Imperial then set back to Metric? (Or however they are described in the settings)

Thanks mate. I tried this but no joy i'm afraid. I rang the garage and they have advised that my software needs to be updated. Im due in this Thursday.

I’m talking about a cover on the driver screen

I’m borrowing one from work. If it fits, I’ll post a picture.

Pardon me if I'm totally wrong, but I thought you could simply turn off the speed notifications? (Speed Limit Mode in the (blurry) photo below)

You can - but it defaults to On next time you get in the car.

Ah, another of the NCAP cockups

Yup; it's one of the things I always turn off when I get in the car (along with LKA). It's just too unreliable to be useful.

I use Waze for all non-trivial journeys (other navigation apps are available), and that has reliable speed limit info on it.

Mine sometimes doesn't and I have to turn it on manually!

I sometimes think modern technology is gaslighting me...

@Yorkshire Hillbilly has put a label over the sign/symbol on the driver screen, not on the windscreen (if I've understood his post right).

Correct, I've used a circular shaped one of these https://www.amazon.co.uk/gp/product/B0CYCJ3S64
I can't stand any kind of lights at night, especially anything that blinks or flashes. I already had them in the house for the stand-by LED on the telly in the bedroom etc.

I variably use Waze, AmiGO or Google Maps ... all 3 offer speed limit indication and vehicle speed. (This is something fairly recent for GMaps - at least it does this on the phone screen; I don't have my own car to check via Android Auto, and AA in the Corsa courtesy car I have is utterly useless so I have to use the phone screen).

What is your experience with Corsa?

I gave up with mine and just stuck a black round sticker over the constantly flashing speed warning

I find that if I don’t go over the speed limit, the car doesn’t flash at me… quite handy really

The Speed Limit Mode stays off when you turn it off - I turned mine off half an hour after getting the car

I think you'll find that statement won't go down very well with anyone on a dual carriageway whose car has seen the 20mph speed limit on a services turnoff!!

You’re right, silly me! I was on the M6 last week and the dashboard was telling me that the limit was 30 for about 50 miles

No, no, silly me! I thought this discussion was about warnings on the dashboard being annoying because they were erroneous, not that people think they are mandatory to obey!

The thread is about speed (traffic) sign detection, not Speed Limit Mode.

What is your experience with Corsa?

It's an ICE car so it feels horrible. (Drove it for 5 hours or so last Friday ... 2.5 hours each way ... and it was really tiring compared a BEV). But as a car it's OK ... manual gear changes are sooooo last year though.

‘The thread is about speed (traffic) sign detection, not Speed Limit Mode. ’

I was replying to Sloucher’s #22

It's hopeless on mine. MK has a LOT of 70mph dual carriageways and 60mph single carriageway roads - all marked as 'National Speed Limit.' The car has no idea what NSL means and shows 60 for the dual carriageways and anything from 30 to 50 for the single ones evidently depending on some random occurrence that I haven't discovered yet.
Other manufacturers manage to get his right 90% of the time, the MG is wrong 90% of the time.

I've an MG4 LR bought in Apr-24. Speed limit detction in the UK is usually wrong but when it does read a speed limit sign correctly then at least that's the speed limit on the display.
On holiday in France in 2024 I switched the car to metric and it would never recognise a speed limit above 70 (kph) - for speeds below 70kph the recognition worked as usual, over 70kph (and there are a lot of 90 & 110 kph limits) it never recognised them.
On its first service the s/w was updated (BTW this did improve the LKA) and I hoped that would fix the speed limit issue. Sadly on holiday this year the problem is still there. I even changed the language to French but still no higher speed limit than 70kph.

Presumably this isn't a problem for Australian, French, German etc. registered cars. What's the secret sauce?

Perhaps as suggested by Yorkshire Hillbilly I should treat the display as if adapting the headlights for driving on the right!

 

[tsedge]

Well, the appropriate fix is to disable speed limit detection on each drive. It is simply immature technology that nobody has a good enough implementation of right now.

Even with cars that read the signs better, there are mistakes and tests have shown that they are easy to defeat with small modifications to signs. It is a hard problem for computers to read signs, they aren't able to do it in the way we can.

 

[Ian Key]

I very rarely notice what speed is being displayed now I've got used to the car. Perhaps it's because I use glasses for driving so my close distance vision is less in focus

If it used GPS instead of a camera it would be more accurate. My old Garmin sat-nav was very good at displaying the correct speed but you still had to be aware of temporary speed limits through roadworks etc.

In my opinion it's technology that's not needed and it's making drivers lazy in their observation of what's happening around them.

I'm afraid that we just have to accept that the cameras and their associated software in these cars are pants. There should be a button you can press to switch the whole damn lot OFF so the driver has full control of the vehicle. Somewhere under that cloak of defective software is a great car trying to get out. The speed limit thing is a useless distraction as it is wrong most of the time where I live. The car warns you that you are approaching schools that were demolished thirty years ago. The latest bonkers interpretation of the terrain is the 'rock slide area' warning when the cameras see an inclined bank on one side of the car. The frontal collision warning is another distraction that needs to be turned off permanently along with the wretched ELK and the speed limit detection.
Incidentally, I recently had an opportunity to drive a 74 plate Hyundai IONIC 5 which has a different set of bonkers 'safety' features (at least they are more simple to turn off). While reaching across to pick up my sunglasses from the centre console, the car told me to "take a break" as it clearly interpreted a sideways movement of my head as fatigue and imminent danger of me falling asleep
