Interesting. Also I’m still very convinced that they update the algorithm behind our backs without an actual software update give my experience last year - here’s a quick recap:
One day, last year, before the ARNR software update, my car was howling down the road. I figured it was tires as it was colder and I was on the PS4S. The noise was awful. I had posted here and nobody knew what it was, and it literally started from one drive to the next. Turns out Tesla had turned on the ARNR behind the scenes on my car, perhaps for testing/pre-release. Many weeks later I got the ARNR software update which added the toggle in the menu to enable/disable, and since someone else said it had created a right racket in their car, I put two and two together and disabled it, - peace and quiet finally! I’ll give it a go again next time I’m out.
Thankfully as of recent software updates Tesla does not automatically turn ARNR on again randomly like they used to, even if you set it to off. So it has at least stayed off since I disabled it.
