Active Lane Keeping Assist - is it possible to turn off permanently ?








On my '20 450, built in built in July '20, I was able to turn it off permanently, and now the new '21 AMG53 also allows it to remain off forever. At least the hard braking is off and I don't have to tell the car every time I start. I don't know if there were updates on either, but my selections stay put.
However---- I sense that, while driving with Distronic active on winding roads, the car seems to slow 2-3mph as I follow another car, even though that car draws away from me (keeping a constant speed).
It feels like "Route based navigation," (RBN) which uses a combination of reading curve warning signs and GPS, slowing well in advance of a corner, to speeds far lower than I like. I DO NOT LIKE the Route Based Nav and I have it turned off, like the Active Lane Keeping. Or maybe it's the Traffic Sign Assist, reading imaginary signs - which I also have turned off.
So it seems like there's some "residual" ALK and/or RBN, or TSA, still doing something. Or, it could be that going around corners just slows the car more than the Distronic can overcome, or something. It's not as potentially dangerous as the ALK, but still causes cars in a line behind "that guy" holding us all up, to accordion behind me. Imagine an AMG holding up traffic!
Sorry for the long-winded description, but we ARE loaded with technology, and sometimes it's hard to separate the effects of features. Alphabet soup.
Any ideas?

On curves I sense that mine is slowing at times by misreading a fixed object as a vehicle. It has happened when there was no reduced speed limit sign.
I had some of these same issues with my GLE 450, they were fixed after recalibration of the Camera & Radar that were apparently out of sync. Distronic has been around for a long time. Malfunctions like this doesn’t make me excited to try a self driving vehicle any time soon.
