Here's what my complaint is. Your driving at a posted speed limit of 75mph. Then a speed limit sign says 55 mph speed limit. The car drops from it's distronic set speed limit to down to 55 mph. Is there anyway to eliminate the car from doing this ?

In ECO mode it's dangerous imho. Just mush if you floor the pedal in ECO. Thanks for reading this.

 

A better example of the danger of this drop in speed is this: driving east from Cisco, Texas towards Eastland, Texas, there is an exit along the road that has a sign saying 'exit speed 45 mph'. The stated speed limit on I-20 is 75 mph. When get to this 45 mph sign and am continuing on east on I-20, the car tries to drop down to 45mph. If there is a car behind me, it presents a danger to me and him since the car is slowing down for no good reason.

 

Yes, and it's all in the owner's manual. Just need to read it. On page 235 it explains where you can turn off all the various speed adaptations. The owner's manual can be downloaded as a PDF as well, so you can search it: https://www.mbusa.com/en/owners/manuals for USA. Go to the respective MB site for your country if not in the USA.

 

Go to the assistance section of the settings menu. Under traffic signs or something like that you can uncheck limit adoption which will stop the car from changing speed based on signs.

 

The second good hint I've found today!

Thanks!

 

Ok. Found it under ADOPT SPEED LIMIT. Had manual online prior to buying the car Thursday and have the car manual that came with the car.

Sat in the car one night and tried to find a setting that would remove speed limit signs and missed it under Distronic.

So thank you SUPERSWISS.

This EQS 450 seems more efficient driving at 75mph than the '22 S Model Tesla I traded it for. Not near as quick/fast but enough for me. Only thing lacking is a supercharger network like Tesla. I consider this car a 'beater' or regional car and not much else imho.

Much more comfortable ride than a Tesla S Model. Tesla S Model supposed range of 405 is more like 220 if you drive at 75 mph and not charge over 90% or go under 20% charge. About 30 miles for every useable 10% of range.

Not nearly enough Electrify America stations on the interstates. Desperatley need one in Corpus Christ

 

Another similar though related piece of digital lunacy and my workaround and a suggested fix:

Problem: On a particular stretch of road, my car thinks the speed limit is 20 MPH when it should be 50 MPH. There are no signs anywhere so I'm surmising that the car is using some internal map based speed limit (DISTRONIC already does this for curves) and my location triggers the slower speed limit. Because I typically drive in the strongest regenerative mode, this change in speed limits causes a very abrupt "braking" by the car, much to my chagrin as well as the vehicle just behind me. In my Tesla it was termed "phantom braking".

Workaround: DISTRONIC doesn't actually brake to slow down, it just coasts until the correct speed is achieved. Unfortunately when I am driving in maximum regenerative mode, the car doesn't coast, I pull strong negative G's and the transition is abrupt. What I do now is to always turn off regenerative braking when I engage DISTRONIC and the car notifies me when the speed limit changes and I can feel a very subtle deceleration. At this point I tap the accelerator pedal and this is usually good enough to reset DISTRONIC back to the originally set speed. To me, disabling the sign reading function is a mistake because when this feature works, it works really well, especially when the speed limit decreases along my route. The only reason I use DISTRONIC is because I would be speeding too often mainly as a function of following the flow of traffic and this would negatively impact my insurance rates since my speed is monitored as part of a rate discount program.

Solution: If there was a way that DISTRONIC could "learn" from these errors, that would be awesome and truly remarkable. In the example above, if the car noted that I manually overrode the DISTRONIC instruction to change speed, say two times, in that same location as defined by my car's GPS, then in the future DISTRONIC would forego reducing the speed at that location because it us clearly a mistake of the system. If more than a handful of drivers did the same thing, then the map database would remove the speed recommendation altogether so that it doesn't happen again to future drivers over that same stretch of road. The same thing would apply when DISTRONIC is reading a sign from another parallel road in error. If tapping the accelerator would restore the original speed and after two occurances prevent it from happening again to me, the vehicle would be a truly intelligent and more than just a car. As a stop gap measure/OTA update, make it an option in the driver's settings to automatically disengage maximum regenerative braking anytime DISTRONIC is engaged. The would be awesome as well!

 

Yes if no speed limit sign is recognized for a while it'll fall back to the speed limit from the map data. Sounds like that road has a wrong speed limit. You can report map issues at wego.here.com and it'll be included in future updates.

 

You info is correct. The problem is that incorrect database info is a recurrent problem.

 

I suppose that depends on where one lives. Don't really have map issues around here. On the contrary. Went 1.5 hours north today for a nice lunch and being labor day I thought maybe I should use Google Maps today, so I did. Traffic was not bad, but there was a road closure and GM took me on probably the worst detour, along with everybody else. The road was best described as a residential rural road littered with patched up potholes. Everything was on it. RVs, trailers you name it. Clearly everybody using GM. Between dodging oncoming RVs and finding the last smooth pavement that was left I was thinking WTH Google. I know there are better alternate roads up here. Heading back home afterwards just to get another data point I started out using GM again, but as soon as I saw that it was taking me to the same horrible road I aborted and started the MB nav which took me on a much more sensible detour with way less traffic, proper wide roads w/o patched potholes all over. I almost forgot, at the end of that horrible road there was actually a sign saying "Residents only", but I guess Google doesn't care. Just goes to show that none of these systems are perfect and GM isn't as good as many make it up to be.

I don't have the automatic speed limit adaption turned on, though. I manually adopt it by pressing Resume whenever I want, and I certainly don't have my insurance company monitor my driving. I did have it turned on during my European Delivery trip, because of all the speed traps over there and it worked quite well, but here in the USA I don't find it helpful. My 26 years accident free driving record speaks for itself and I do drive an AMG, so not exactly driving the speed limits. Radar detectors are legal here.

 

The speed traps in Europe are ridiculous and tge speed limit seems to change ever 5 miles on the highway, its nuts!
Its almost impossible not to break the speed limit!

 

Yes, exactly. I managed to get only one ticket with the help of the automatic speed limit adoption. It was at the end of an unlimited section of German Autobahn. Didn't slow down fast enough and got flashed with 30 kph over or something like that. It was cheap, though. Speeding tickets in Germany are more of a slap on the wrist. This June I got one in Switzerland for 1 kph over. I kid you not. I am Swiss, but they've lost it back home. Haven't received the actually fine yet, but got an email from the rental car company which charged me 30 Euro for the trouble to send them my contact info. They attached the letter from the police and I couldn't believe my eyes. Literally they went through the trouble for 1 kph.

 

Yep I got one in Switzerland for 4 km. Stupid. Basically it just another tax. Switzerland is **** retentive that way. Made trillions stashing away dirty money but a 1km infraction is a no no. Theres the Swiss for you. Singapore is the same thing but, in addition, they cane you....in public !

 

Apparently my efforts to get rid of the automatic slowdowns worked. Today, I drove a 65 mile run with Cruise Control and Distancing on, and both worked without any changes in speed where they had occurred before. Fingers crossed.

 

Congratulations. You've just removed what i call a dangerous 'feature'.

By the way. Have you ever been in ECO mode and had a situation where you needed to accelerate quickly ? Try that while distronic is set to 75mph and see what happens.
In ECO mode I can step on the pedal to the floor and it's mush. Goes nowhere. I''ve given up ECO mode as dangerous and leave it in Comfort or Sport. No loss of range have I seen doing this. Just like in a Tesla S, If you take it out of chill and put it in Sport you get the same range when traveliing with adaptive cruise (I don't care for what Tesla calls it) as long as you leave it in adaptive cruise and don't stomp on the pedal while traveling

 

You can get instantaneous acceleration in eco. All you have to do is mash the accelerator and keep it there.
