My car is vision-only running 2021.3.103 and AP seems to work well for me, I'm only 350 or so miles in but use AP daily going to and from work and have not yet experienced any phantom braking.

Discussion: Tesla Vision system for Model 3/Y

I think it's highly situational and a function of those roads. If there's a combination of visual and/or RADAR-reactive things on a given road, the same problems will keep happening.
I know there were a couple of spots on a regular route of mine that generated phantom braking on the highway for me, and over time, they were all eliminated. Phantom braking still happens occasionally on different roads, but those consistent spots got fixed.
The 75-> 45 is exactly what people are referring to when they say "phantom braking." It knows you're on a freeway, but the system feared that something was stationary on the road ahead and began to brake so that it *could* stop in time if it decided it needed to.
The other things, like the bouncing in the visualizer, are common. It's important to know that it's *just* the visualizer. The car's internal model of the world is not designed for pretty rendering on screens for humans. It's designed for fast in-access memory to a probabilistic model of the world around you. The visualizer you see is an add-on layer being generated by your infotainment system based on checking in on that probabilistic model now and then. Don't stress over the dancing trucks; it's doesn't mean your car is clueless about your surroundings, it means your infotainment display is unclear about how the inside of the car's real "brain" is thinking.
You can do the double-thumb reset and reboot of the whole infotainments system *while* driving on the highway *while* the car is in full Navigate-on-Autopilot, and it will keep driving itself just fine. You're not rebooting the car's real "brain," just the infotainment system which is there to interface with the humans.
Apparently it was nowhere near the many weeks a lot of people were intimating.
An update is out now,
>Tesla has started releasing a new software update (2021.4.18.10) that is bringing back emergency lane departure avoidance and smart summon, and it is increasing the Autopilot speed limit from 75 mph to 80 mph.
from Tesla releases new update for vehicles with its new 'Tesla Vision' system to restore Autopilot features - Electrek
Also notable, to me:
This jibes perfectly with my suspicions earlier in this discussion. RADAR is very, very noisy, and it's making more problems for the system than it solves. Some people keep focusing on the tiny minority of circumstances where RADAR gives an advantage and ignoring that it's generating problematic noise most of the time. The system spends processing time and energy overriding the noise all the time... and it can even be hampering the effort to actually get better on the pure vision side of things.
This is not correct; it cannot determine where an object in front of the sensor is, only how far away it is.
Given two objects in front of the sensor, it can estimate the angle between the two objects; that's the angular measurement being referenced.
With a very small angle between two objects which are 5 m and 10 m ahead, you can guess the second object is the car two ahead of you. With a large angle between them, it could be in an adjacent lane (or an overhead sign, depending on whether this angular measurement is planar or not.)
My bad....the message is that I can't turn OFF the wipers but I can manually changed them from auto.
NoA is Navigate on Autopilot
I think it is from driving conditions. Today in the rain of all things, the phantom braking went from 30+ times to about 10. And coming home in the nice daylight it had more issues than in the dark rain, go figure....
Hopefully you are not taking your car to the car wash, but if you do, remember to turn off the auto wipersMy car is vision-only running 2021.3.103 and AP seems to work well, though this is my first Tesla so I don't really have anything to compare it to. I'm not getting phantom braking (though it can be overly cautious when it sees people walking on the sidewalk resulting in a dramatic slow-down). It has even done well when driving into direct sunlight during sunset. Overall I've been very impressed and my trust-level in the system is growing. I do wonder if those reporting a poor experience are running 2021.4.18.2?
As for the auto-wipers... I live in Vegas, what is this "rain" you speak of?
Do you have a reference for this? The angle stated in the data sheet does indeed appear to be the angular resolution. It is essentially the beam width of the array and specifies the closest two objects can be separated in angle and still be recognized as distinct. How Tesla uses this radar is anyone's guess, but the device itself does appear to be a scanning phased array device capable of both radial and angular position measurement.
Just got 2021.4.18.10 and can confirm restoration of ELDA and Smart Summon… will test auto-steer to 80 tomorrow.

We own a 2018 model 3 and 2021 model Y with no radar. We have no issues with the high beams on either car. I think they work pretty well at staying on when need be and turning off when other cars are identified. Yes, they go off on some false positives, but come back on in a few seconds.
Both cars have occasional issues with brake checks, but neither will brake from 75-45, or perhaps I’m ready to intervene much quicker than the average person.
Also, as an early FSD adopter, I can say that the early FSD 3 systems had issues that got better over time. Constant improvement is the key here, not expecting an out of the box perfect level 3-5 system. If Tesla didn’t use all of us as beta testers, we’d likely be confined to a waymo type system limited to geofenced areas.
So my car officially started bugging me to upgrade to 2021.4.18.2 which adds the interior camera monitoring. I currently have my camera covered and dont really want to have to uncover it but fear doing so will stop AP from working. Has anyone with the update tried covering the camera to see if it stops AP from being activated?
Very nice, I hope to be seeing this SOON. The phantom braking has improved now that I don't allow the high beams to come on but during the day, well still getting them.

I shot a video earlier today, while not purposefully truing to film autopilot/ Vision you can get a good idea,
Few points. I feel the system does many things well, but there are definitely some things it needs to work on. No FSD on my car
- Curvy backroads. Does a pretty great job, if there are bright lines painted that helps a lot.
-Autohigh beams are laughably bad. This causes no remorse and blinds people that are 200 yards off and just doesn't care.
-When a car in front of you slows down and turns right for example. Even AFTER the car is completely out of your lane of travel, the Tesla still continues to slow down. Takes a good 2-4 seconds to get back on the gas
I've had a few false "front collision" warnings come up at night in the fog. Nothing was there, but it freaked out.

2021.4.18.3 no issue. Theor
Well that was interesting.
575 Km, first half in daylight, second at night time.
Daylight, no issues at all to report.
Nighttime,
- 6 or 7 phantom breaking occurrences. They mostly seemed to happen when car is about to go up a hill. Like road level in front is higher and mistaken for a collision box??
- Twice got warnings that my driver side pillar camera was dirty. Probably because road was too dark and no vehicles behind.
- Blind spot monitoring worked very well as it saved me once.
- Vehicles on side or rear of the car don't show up in the 3D render until they overtake me.
- vehicles in front show up on the 3D render when they seem way closer to my car than in daytime. And this translates to autopilot slowing down much later than in daylight (I have 7 car length distance set).
My phantom braking also occurs going up or cresting a hill, especially when another car is coming over it in the other direction.
This is all daytime driving.
2021.4.18.2
Maybe .10 version will help.
