You cannot turn this behavior off persistently -- you need to open car settings and disable it every time you leave Park. My guess is that some jurisdictions mandate this behavior.

When this "feature" triggers you have a short window in which to do _something_ to tell the car that you are paying attention. Your options are either: accellerate or brake. If you do nothing the car may apply full brakes and bring you to a full stop, regardless what is behind you.

This has been happening for much longer than that -- at least as early as Winter 2019, when I unintentionally brake checked a Prius after merging while going over 101 @ Rengstorf.

What behavior are you referring to? We are talking about autopilot, and possibly FSD, neither of which are engaged by default (obviously!) What do you mean they can't be turned off?

Again, what is this? I have a Tesla, and I'm not aware of any feature that requires me to accelerate or brake to prevent the car from stopping itself.

Automatic Emergency Braking. You cannot turn off AEB persistently.

Before the car emergency brakes, it will warn you via "Forward Collision Warning"; the screen will show the object it thinks you're about to hit in red. You can set this to "Late" to reduce false positives -- but if you do, you'll have less time to take action yourself. So now I set it to Early.

After a FCW, you have a small amount of time to do something before the car will do something for you. The M3 manual describes AEB here:

https://www.tesla.com/ownersmanual/model3/en_us/GUID-8EA7EF1...

It also explains "Automatic Emergency Braking is always enabled when you start Model 3. To disable it for your current drive, touch Controls > Autopilot > Automatic Emergency Braking."

This article is about autopilot phantom braking, not AEB. I've never had AEB trigger, or heard of it triggering when it shouldn't, but maybe I'm unaware.

Phantom braking includes self-driving/cruise and ADAS, e.g. "What is phantom braking"

> Phantom braking is a term used to describe when an advanced driver assistance system (ADAS) – or a self-driving system – applies the brakes for no good reason

(AEB is part of ADAS)

i had it trigger twice: once to prevent a frontal crash that would have been my fault, and once during a storm. i am very glad that it is there; works extremely well.

Can you put some tape over the sensors?
