MG4 Lane keep assist

[Rip Van]

"I certainly don't like LKA but getting into the habit of turning it off is all that's needed to really enjoy the car."

Not really, if you're one of the unlucky ones who also suffers phantom braking and other issues.
@yellowmitch sounds like you're in exactly the same position as me then, bar the PCP.

...turn AEB off as well then.?‍

 

[NLMGSAN]

Luckily (or unluckily) I own the car outright and its mine in its entirety. It has every possible update and is at the latest of everything.

Now in fairness, it's considerably better than it was, and either me or the wife can easily turn off LKA/ELK with the pull down menu ON R59.

But the foibles with this (wifi hotspot not working etc) and some other silly things mean that I have no confidence that anything will ever be completely sorted by the less than helpful lacklustre manufacturer.

For that reason, I am considering changing the car for something else, despite loving the driving dynamics and exterior styling

For the wifi hotspot there is a solution. Can't find it directly but it is here somewhere.
Edit: Hotspot fix

A) I don't really agree with having to turn off all the safety features, they should actually work, and it's rather apologist to think otherwise. I paid extra for the fully featured car with all the safety features as I sometimes do a lot of mileage, I shouldn't have to disable these things because they're faulty.
B) If only that were the only other issue.

That's a valid point.

But I'd prefer not to have so much computer involvement, I still trust this old brain more than a cheap computer. With unknown software.

There's a history of undiscovered software bugs killing people.

Coming from cars(s) where it worked borderline flawlessly however, you can understand the frustration, and as I say its unfortunately part of a litany of errors and random system faults.

I'd be happy to use these aids if they were fit for purpose. I find LKA just wrong particularly when its bright with its tendency to pick up tar lines on road repairs and jerk the steering, and traffic sign recognition unreliable either picking up signs on side roads or not recognising main one due to them being dirty/partially obscured by vegetation. Its not restricted to MG though I was chatting to a friend who has an ioniq 5 and he has the same issues on our local roads.

My MG 4 gives a small wobble on steering wheel (LKA) but never steered me into traffic and never will maybe I don’t hang on to the wheel with grim death and my lane positioning is pretty good so I don’t have all these dramatic driving moments (try landing a Cessna 150 in big x wind ) my 17 year old granddaughter makes no comment when driving as she regards this as normal car output.
For the price absolutely awesome vehicle.

I think the problem is that most (non motorway) UK roads are poorly marked narrow full of potholes and indifferently repaired patches that just confuse the LKA. Most of the roads around here don't have markings so LKA remains in the ready (white) state then it will pick up a shiny repair (its worse in the summer) and decide its a white line which is unfortunate if you are crossing it and jerk you in one direction or the other. It reminds me of driving my old beetle with shot king pins, if you hit the brakes hard it would pull to one side or the other.
As for the 150 I didn't do much tailwheel flying after completing the training but had plenty of X winds in 152/172s, Cherokees and most fun in K8 glider with a castoring tailwheel.

I've hard it happen even on well marked roads, it does seem to vary from one MG4 to another however, which suggests maybe firmware/hardware differences as well as software. There have to be some significant variables for it to be this variable amongst owners.

I think the only time it has happened to me on a well marked road was when a properly repaired large patch had a tar line boundary running parallel to the direction of travel and it decided to move me over so I didn't straddle it. As I said elsewhere the system only works well in very specific circumstance and as such is unfit for purpose, on many UK roads.

 

[JeanLeFlambeur]

So where it's been described as LKA taking control or moving over, does this mean that even if you have the steering wheel gripped it will force you over? Is a firm grip on the wheel enough to prevent the LKA from moving the vehicle?

(I appreciate we shouldn't and don't have an iron grip on the wheel at all times, I'm not suggesting that's reasonable or the solution)

 

[Tyranuus]

It yanks the wheel relatively hard, and takes some notable resistance to let go, more than it should IMO. I'm used to fighting it now but it's unpleasant even as a 6'3 guy. It has got slightly less heavy handed with updates but if you're driving using relatively light force due to the relatively light steering its a significantly noticeable yank.

You certainly don't want to have a firm grip all the time you're driving, on a long trip that won't be good for your body. It happens very quickly, and you can overpower it, but us humans have a reaction time,

 

[OriginalBigAl]

I have said this before but its main problems are: inconsistency, because of this we cannot trust it. If it was consistently bad we would complain but turn it off. Conversely if good, we would leave it on.
Because its in-between and on , it is not a pleasant relaxing driving experience ( what's it going to do next ) and because of this lack of trust do we actually know its going to work when we actually need it, again unnerving. like others I resent paying and having to maintain systems which are forced upon us , whilst the powers that be say I shouldn't I am sticking with Mark 1 eyeball until threads like this are no longer replied to.

Precisely. And between the SE and the higher specced versions differences exist as well. Then you have various circumstances where systems should operate.
If, as OriginalBigAl correctly states, systems are not reliable and predictable, controlling a car becomes a bit of a lottery. The worst of it all is that you are 'forced' into using these systems because of legislation. Going around this (disabling systems) is purposely hindered because of the assumption that using it improves safety. However, that is a concept of safety on a population base. The problem is: I'm not 'the population', I pay for the thing and I’m responsible if it fails to improve safety. And, according to MG UK, the latter is not the case either.

There's much more of a history of unknown people killing other people on the roads due to their 'old' brains.

Can't argue with that!

Never done glider, 1st solo was in a Beachcraft skipper still my favourite to this day, and really my LKA is same as VW and Subaru in feel maybe because I have light relaxed grip on steering wheel.

Ahh yes, but is there a history showing that computer "safety features" have saved more lives than they've ended?

Of course. ABS is on simple example. Taking it a step further on motorcycles, C-ABS (cornering ABS) utilising 6 axis IMUs is a definite life saver, particuarly is wet conditions. For cars, traction control in poor grip conditions has saved may accidents, a percentage of which will have been potentially fatal.
