anti collision emergency braking

I have no such problem with my butler walking in front of my car with a red flag. Felicitations Jacob?

Emergency braking has happened twice during my one-year driving experience with MG. I believe MG's computer has a 1/2 second delay in response in these situations. For instance, when the car in front had already turned left into a side road completely, the MG's computer thought that the car would collide and applied emergency braking, even though there was no car in front of it.

I have never experienced this issue with my other Mercedes

Out of interest has anyone had an accident because of AEB?

I had an accident because of phantom AEB on the motorway in a gen 2 ZS EV. I think I c****** my pants.

104km to a complete stop because of ‘someone’ walking on the road.

I turn pretty much all the "safety"features off or to alert only, every time I get in the car. Also if I could just have normal cruise control rather than adaptive that would also be fine with me. Not a moan as I really love the car but it's just trying to be too clever and not particularly making a good job of it.

Shouldn’t have to switch them off every time you get into a car.

Unlike Teslas opt in system, certain pilot features can’t be switched off.

Has happened to me once or twice but I've learned to anticipate it now

So I was driving up a steep hill, approaching road works where the road was down to a single lane controlled by temporary traffic lights.
Foot off the gas so was slowing quite quickly, the car in front was turning left just before the roadworks, the traffic lights turned green so no oncoming traffic, as I put my foot down to go around the car turning left and enter the road works, the car decided it was going to be a collision and threw on the anchors,
now I'm all up for these safety features, but the gap between me and the car in front was still large enough for me to safely go around and our speeds were well under 30.
The emergency braking caught me completely off guard as my response to the upcoming situation was completely different to the cars !!!!
Not so sure these safety features are such a good thing as if me having to swerve out the way or increase my speed was the only way to avoid an impact, the car would possibly not allow you to do that , just a thought .
Any other experiences similar ?

This happened to me. Clear, straight road. Had the ACC on at 79km. Nothing in front of me in my lane. A lorry was in the other lane coming towards me and my car thought I was going to hit it? Hard braked way to much. Frightened the life out of me, thankfully the car behind me was well behind me. I now turn off the AEB every time I get in. The alert only is fine

I've had this happen a couple of times.
Apart from making me curse it scares following drivers when doing an unnecessary emergency break.
All designed to make us leave greater distances between cars I suppose and it only needs to be right once to make it worthwhile.
Are there insurance implications of you turn off these systems - my insurance was cheaper because the car does have them.

The safety features shouldn't directly affect insurance. What they do is increase the NCAP safety rating of the car, which may indirectly do so.

Auto Emergency Braking works with ACC on or off. On the times it's happened to me, when I've analysed the situation then it's been me that was wrong each time. As a human we make assumptions, like assuming a car is turning left at the next junction because their indicator is flashing. But what would happen if that same car slammed on their brakes because something was blocking their exit from our path like an unseen child? In that situation our subconscious assumption that the road would be clear by the time we got there would be wrong. It may be annoying that it's pointing out bad habits, but it's actually safer than a human driver 99% of the time.

I've seen the scenario a couple of times where a car is turning left in front of me and a pedestrian walks across the side road in front of them and they stop, my car warns me with a beep, then if I don't take evasive action like braking or swerving around the car if it's safe to do so, it brakes. All as it should do.

My ZS Gen 1 collision control has never activated in over 20,000 miles. In fact I have often worried it isnt working. Not that we drive too close ever, but it has beeped at us a few times.
Do I need cruise control to be on for it to auto activate?

It works independently of cruise control, the fact that it's never gone off indicates that you're driving it as intended.

Hmm, yes to an extent.

But following a car at a 2 second (double chevron) safe distance on a dual carriageway, whilst it safely takes an exit slip road, and then the car jumps heavily on the brakes just isn't the right response. It's misreading of a situation that happens safely and legally all the time.

I've actually had it slam on the brakes in response to a stationary car sat in a road running parallel to the one I'm driving in before...

Definitely better to have false positives than it be insensitive, so that's an upside.

It is over sensitive in ACC mode only. My ZS EV brakes on slow arching corners and vehicles driving towards me in the opposite lane. It isn't the AEB because it only happens in ACC mode. More annoyingly, the Lane Assist actively steers the car towards the kerb which then activates braking.

I much prefer ISA/MSA modes (which does use regenerative braking). It's just a nuisance you have to go so deep into the menu to activate it each time you start the car. No reason it shouldn't save the last setting. MG tech's should count the steps it takes to activate ISA/MSA.

The slowing down in corners thing isn't a phantom brake/collision detection thing. That's just it's actual intended behaviour..."driving like a frickin Toyota driver" - Teslabjörn.

I've found it overly sensitive, period. Doing just over 25 on a relatively wide road, car in the oncoming lane waiting to turn...presumably it perceived that as the hazard and slammed the brakes on so hard, I nearly had heart failure. It was completely clear ahead, not even any parked cars...no reason for it at all that I could see. I'm just thankful there was nobody behind me.

In the space of a week I've had this happen a couple of times, and some other front collision avoidance warnings when there's nothing ahead. I'm beginning to wonder it it's faulty, or if I need to tinker in the settings a bit more.

The Kona was a lot worse than the MG for phantom braking.

Your butler might take issue with you running him over regularly ?

If that uses the same tech as the MK1 to gather speed limit info I'd not be putting much faith in it ?
