Sometimes I just let it (phantom) brake for a while to see if it can recover, if there's no one around. Maybe they waited 2 seconds for the heck of it?
I can imagine that might be what they did.

I can't wait for the next update! Phantom braking is driving me nuts.

Everyone who drives a vision only Tesla doesn't view braking for no reason to be an emergency unless they know that there is traffic behind them, so a "F you Elon" may be shouted before you actually press down on the accelerator. Sometimes I let it go as long as the car wants just to see how stupid the system is.
In fact, I suspect that laservet allowed the car to slow, waiting for it to stop braking for no reason to see how bad this particular phantom brake event was before he decided to press the accelerator... when it got down to 40 mph with no sign that the car realized it was NOT an emergency brake situation he pressed the accelerator to avoid driving 40 mph on the highway.

PS: I am not saying "yes it did" calling you out on a lie... but you sure did call laservert out on this as it it were a lie...

It was pretty clearly a wild exaggeration. The claim was he was going to get rear-ended, which certainly sounds like an emergency.
Frankly I see this a lot: people experience hard braking for 300ms or whatever, and it's surely scary. But that maneuver changes your cars speed by 5mph or so! It's just not "unsafe" in the way that a lot of people tend to assume. Cars stomp on their brakes under human control in traffic all the time, and we all get by.
It's just a meme. Everyone gets clicks and upvotes and agreement if they shout "phantom braking", and so everyone comes to believe this is some kind of horrific safety issue and not just the control authority tuning glitch that it is. I mean, I'm up to maybe 800 miles under FSD control now, and I've seen my share of "phantom braking" events. I've never once seen the car come to a near stop in highway traffic or otherwise place itself in harms way doing this. It just jerks you around and scares your passengers.
He never said there was a car behind him, he said that he hit the accelerator to avoid getting rear ended... I interpret that to mean "if I am doing 40 mph on the highway and the car continues to slow down, eventually someone is going to come up behind me"... it is a lot easier to write "I hit the accelerator to avoid being rear-ended". I hope laservert clarifies this in a future post.

I'd argue the Y/3 should likely be in their own partition due to the "Vision Only" and hardware variance.
You can create thread there and name it vision only cars phantom braking.
Yes, you want to suppress all thoughts of vision only system not being perfect, so you want to shuffle them off to an area that nobody reads... but since reporting the thread didn't work, you can accept the moderators decision and just not read the threads that make you sad. Have you asked them to lock the thread yet? I figure that is your next step.

Lol I didn’t report anything. But yeah keep it going. Also thanks for advice. Reported

They're making model 3s and model ys with vision only, but they're keeping radar for model s and x? Is this true?

Driving to San Francisco from LA, I had a lot of phantom braking on a clear day. I kept a foot on the accelerator and just stomped on it every time I had a case of phantom braking.

Is it possible to set these cars to simply hold a speed, so that they can at least be as competent as a 1970's car? I'm more than happy to perform the "traffic awareness" function myself.
Nope. Wish it were an option, as I would find that far less stressful than having to hover over the accelerator "just in case".

Can you just give it a rest? People were just disagreeing with you, not staging some kind of conspiracy to suppress your Extremely Important Opinions.

??? What are you ranting about? I never said it took two seconds for it to decelerate to 40. That's a fabrication on your part, don't attribute it to me.
Others understood what I said, not sure why you had such trouble. The car decelerated hard, and unlike all the previous phantom braking events in which it decelerated 10-15 mph and then ceased decelerating, in this case it continued to decelerate hard. While it would have been interesting to see if it was going to bring itself to a complete stop, traffic traveling at 75-80 mph including an 18 wheeler in my lane was coming up behind me and it wouldn't have been safe to allow it to continue to decelerate. So I accelerated back to speed but I had to continue to press the accelerator because even though navigate on autopilot was still engaged the car decelerated hard again each time I took my foot off the accelerator. That is completely different behavior than it has shown when phantom braking in the past, in all the other episodes I could accelerate back to speed and the car would continue at that speed without braking a second time.
Not sure where you got that 2 second nonsense, maybe you're having a bad day.

It pretty clearly was a wild exaggeration on your part. Where did you get the 2 second thing? I certainly made no claim, you just made that up. As far as getting rear ended, driving 40 and still decelerating hard in the fast lane of the interstate when traffic is going 75-80 mph is quite likely to get one rear ended.
Again, this was clearly not like the phantom braking I have experienced in the past.

Math.
Look, if you really were about to get hit then post a video, the car has a 360 degree dash cam available at the push of a button. If the car merely braked hard and you let it, you weren't "about to get rear ended" and I think it's borderline irresponsible to say so, because it leads people to believe that a system under your affirmative control was unsafe for other drivers.
