In my case I was leaving one stop sign, heading into another stop sign. Road was straight.

Does anyone know how I can reduce the sensitivity of collision avoidance? Can I completely turn it off?
I had 2 Audis that would both occasionally do this in a specific area, but my wife managed to rear end someone without the system activating. I didn't option it on my 911. The system on our BMW will false beep with warnings occasionally but has never slammed the brakes in error like that.

There has to be a way to turn it off. What do you do when you’re on a track?

This tech was not ready for prime time in 2020. I certainly hope it works better now.
Had this as well on mine. Problem seems to be, the system has been transitioned from the 1st gen to 2nd gen, and was developed probably around 2013. It would also break for cars which were already gone, which means it lagged by 1 or 2 seconds.

Never happened to me in a 992. Not in mine, and not in any other that I have benn driving previously.

My 2019 Cayenne would do this also and sometimes very significantly like on an upward parking lot ramp. Very scary when it happened.
