Just picked up by ‘25 GLS580. It appears that the automatic lane change feature of last year‘s active lane change assist is no longer. Just tested it on the interstate for 20 miles and could not get it to automatically change lanes. You have to initiate the lane change with the turn signal. Granted, if you’re not used to the previous automatic function, it can be scary if you don’t know it’s coming. But on the open road it’s was a nice feature.

Lets see if it becomes available by subscription....

I doubt that, r u sure you are not missing anything in the setting menu? Why would they remove a feature like that…

My MY24 GLS 580 does not have automatic lane change assist, only active lane change assist. Perhaps you are confusing the GLS with the S-class (which I think has automatic lane change assist)?

Guess I made the wrong assumption that it would be included on the GLS. It was included on a loaner ‘24 GLC.

My 2022 GLS has the auto-lane change assist (and my 2018 W222 had auto-lane change too). I wonder why they removed it from the facelift GLS (unless it became a separate option from the drive assist).... The reason I like it is because I trust enough as a 2nd verification that left/right side is free and clear to merge into, plus that I get to keep the auto lane and speed assist all turned on without disrupting them or the need to re-engage them.

When you think about this feature as being the other driver in the left hand lane in the process of passing you, an activated turn signal prerequisite seems like a good idea. I'm almost certain I won't see you eyes divert momentarily to your rearview mirror. And even at only 60mph, I'm moving about 4 car lengths per second.

you shouldn't be closing on another vehicle at that rate though. And if you are you won't see the other driver make a head or eye motion either. As the faster driver I actually trust a computer to see me coming more than a human.

Driver assist features are yet a long way away from dealing with the way people really drive. A few minutes on an interstate beltway around any major city at rush hour reveals their limitations.

Are you sure that you don't have active lane change assist? That's the one where you have to tap the left or right turn signal before it changes lanes.

The automatic lane change assist will do it for you without your input.

All "assist" functions off in traffic, for me. Humans in adjacent cars are too unpredictable.

I think being in a driverless Robo Taxi would be a frightening experience for me as well.

My 2020 W222 does not have an auto lane change feature, only lane change after I initiate it, by blinker I think, I usually turn some anyway. It’ll follow someone with its adaptive cruise to a mind numbing low speed until I notice it and initiate the pass. Auto vs active lane change?

Car gets confused anytime I wear these.

That would be active. At least I think that's the term.
I call it "active" because I have to actively pay attention when I use it. Because odds are, since I'm using Active Steering Assist, it'll require me to grasp the wheel mid-pass, abandoning the pass and confusing all the drivers around me. Including myself.
So I'm actively poised over the wheel, ready to do my part.

I use both - Active Steering Assist (NOT Lane Keeping Assist) and Active Lane Change - on the open road. Makes the driving much more pleasurable.

I hear you about inadvertently following an ever-slowing driver.

I don't see how anyone has this problem. Ours will roar up to a slow vehicle and then mash the brakes. If the slow vehicle then moves over it will mash the accelerator to get back to the set MPH.

Bummer. The 2024 GLS 580 is fairly smooth in that situation. It does accelerate with more oomph than my other vehicles, but it's not jarring, and I prefer it, especially since I'm in Individual mode with Drive set to Sport. In Comfort Drive mode, it seems to accelerate slower.

I think the previous poster and I were talking about the same thing, which is following a driver for miles, who slows gradually, and you do too. It happens.

My wife often falls onto that category - she doesn't like being in the fast lane. I don't like being in the slow lane, but I don't usually roar up to anyone. It's kind of Road Ragey.
