I thought i noticed something similar last night but with only hours in the seat i didnt know how it was supposed to work. I found it fascinating that when indicating the car knew when i had changed lanes and auto cancelled when i had finished.Couple of things I noticed today, on EAP was trying some lane changes and it wasn't making me 'tug' the wheel like it was when I was doing it in the old Tesla (back in October, so several versions ago). This and using the indicator buttons rather than stalk made changing lanes SO much better.
The other cool thing I noticed, which I didn't see the older M3 do, when I change lanes into a turn lane, the auto indicator cancel seems to recognise the fact it's a turning lane (displays the turn arrow in the visualisation) and keeps the indicator going until you make the turn. I had auto cancel off most of the time I was driving the 2020 M3 as there were a few times where it wasn't quite accurate, but I'm pretty sure even when I had it on, it never did that (could be wrong). I've found the auto indicator has worked perfectly so far, just occasionaly on a small roundabout it takes a little longer than I'd like. to cancel the left indicator after exit.
In a normal car its 3 flashes or on until you cancel.
I was getting a few warnings saying my right camera was obscured, but the message went away. Not sure what that was about.
Havent driven the car today, its been in the shed getting accessories and ive been drilling down into the settings.
Did a lightshow, that was cool.
