After update 2020.36.3.1 (9/9/20) my M3 stopped for this stop sign. Came to a dead stop about where that car in front of me is now, about 50ft beyond the sign. In case it's not clear, those stop signs are for the road joining the road I'm on now, not my road. Even prior to 36.3.1 I have experienced phantom braking at this location before. I didn't realize why until now when it came to a full stop with the message saying stopped for traffic control.
I'm anxiously waiting for the neural net update.
