    Has anyone noticed when driving without AP 2.0 engaged, getting collision avoidance alert tones when approaching a stop sign/intersection a bit too quickly, or when rolling through without a full stop ? This, with no vehicles in front ?

    I noticed this shortly after the 21.9 update and experienced multiple times when driving back streets over the course of several days. I didnt notice that function before.

    Also noticed this, didn’t think anything of it at the time but in retrospect there wasn’t any other reason for the beeping

    I noticed yesterday for the first time a slow down on a back road on AP when aproaching a stop sign at a T junction. I commented at the the time "wow, did you see that" to the others in the car, but did not go back to retest. Not sure if it was the T junction or the stop sign... V2018.24

    Quite annoyingly, I get them when passing parked cars in my subdivision... even giving them a wide berth. I think it is more prevalent when I am driving on a curved section of the street, and perhaps it looks to the system like the car is directly in my path. Didn't do this on earlier firmware.

    I have this happen on AP1. For quite some time. Makes sense - road curves, no lane markings to guide the computer, looks momentarily that you will drive into a stationary car.

    But, I though the Tesla couldn’t “see” stopped vehicles that were stopped when they came into view? Maybe the difference is the lack of lane lines within the subdivision?

    I will be interested to test this on the drive home, i normally disengage AP when approaching stop signs, how far are you from the sign when you are getting an alert?

    It varies but when I saw this it was at the point where I should have stopped. It wa similar to AEB alerting and I’m not convinced the signs were the cause, but it seemed like it at the time.
