What are owner's experience with the Steering Assistance? Coming from Tesla I'm surprisingly disappointed. Just today I was in the right lane and it tried to turn off the freeway onto an offramp. I find I have to watch it much more closely than the Tesla. Not to imply that I didn't watch the Tesla, but the EQE will stray right across a line at random times with both Lane Keeping and Steering Assistance enabled.

The Distance Assistance cruise control works great, but it's activated with the Steering Assistance, or vice versus, so I'm constantly having to pull up the menu and enable or disable Steering Assistance when I want to use it. Much less convenient than being on a stalk.

Hmm, interesting. Our cars don't seem to have that issue with Distronic. I've been using various versions of Distronic for over a decade, and can tell you that while earlier versions with steering assist did exhibit the behaviors you've mentioned (my old W212 E-class was notorious for wanting to take exits), I don't see that problem at all on the EQEs. The progress they've made in lane centering and handling diverse terrains and road conditions is stunning. I will say that on occasion, the car will "acknowledge" the exit lane with a slight tug, but won't actually take it. And if there's a car in front, it simply continues on as if nothing had happened.

Interestingly, Kyle Conner in the Out of Spec Reviews YouTube Channel, which is well known for testing all sorts of brands and models of EVs, recently took a '24 EQS over their Hogback Challenge, an ADAS torture test of sorts in the mountains of Colorado. The EQS scored higher than all the other cars they'd tested to date. There are rumors that a BMW i7 has also scored well, but they haven't posted the video, so for now, the EQS has done the best in those very scenarios. Here's the video:

Note that the challenge has featured a couple of Teslas and many other cars, and the MB ADAS system consistently scores at the top.

Not sure if this is on all trims: Steering Assist will use lane markings as well as trying to follow the vehicle ahead. So if the vehicle ahead takes an offramp then the MP may try to follow.

It's standard on Exclusive trims and up. Premium doesn't have it by default. MB actually made a video explainer about 5 years ago showing how Distronic won't take an exit even if the car ahead of you does. It's something that was a problem on first generation Steering Assist, but today your car will continue in its lane. There may be some very specific exceptions to this, but in general I find it always follows the lane and ignores the exits as one would want it to do.

The typical off ram on our highways are split configuration, like a Y where there the lane open up into two lanes. Following a vehicle would likely take priority, and this could be going straight or taking the off ramp. I am always in control so this has never bothered me.

Since ADAS is not really model specific, I answer more generally. I have not experienced this with the latest MB systems. Even my 2019 C63 doesn't take exits, unless the route guidance indicates that I need to get off the highway and route based speed adaptation is enabled, where it automatically starts to slow down for an exit. In my experience the MB system also handles highway forks better than what I've seen Teslas do. Maybe the latest Teslas are better at that, but it seems one can still find recent YouTube videos of Teslas veering off the road even with the latest FSD. I've never had an MB with Steering Assist suddenly veer off the road. The MB system occasionally requires the driver to help along and make occasional steering corrections, but nothing like a doomsday maneuver like Teslas seem to occasionally do heading for the side of the road, a wall or bollard or something.
