AGIAN, here is an example from yesterday. I pull up to 12" warning and then move another inch or 2 to keep people from squeezing between my bumper and the bollard. This can ONLY be done with ultrasonics and NO WAY vision could tell me this.

Tesla replacing ultrasonic sensors with Tesla Vision

there's no way to reuse and land effing rockets back on terra firma, either...but...
never and no way are not Tesla terms.
Yeah i know it's Space X doing the impossible. so what.

Why couldn't vision do it?
If it sees the bollard and ground and determines its position when X inches away, why wouldn't it be able to move another X-10 inches forward?
If they handle it the same way they handled the deletion of radar it will go like this. When you go into the app to accept delivery of your car there will be a pop up explaining the the change. You will get the option to accept the change or cancel the order.

FWIW- nobody ever said that was impossible. There's stuff on doing it that's decades old.
What people said was it couldn't be done economically.
Elons strength isn't in doing things literally not possible.
It's in designing solutions to really hard things in a way that makes them cheap and easy to mass produce.

So I got my vin on 9/21, being delivered on Friday, i assume based on what the Tesla release says I will still be getting the sensors in my car?
Accept that many people felt that Bluetooth headsets did not have the same fidelity as cabled headphones, and there was quite a backlash. There were petitions to demand the return of the jack, but Apple stood fast. Eventually the market changed and people accepted the new way of doing things. New Bluetooth standards increased fidelity, and new wireless headphones started giving us better sound quality.

i sure hope so. i prefer sensors for park assist and the like for now.

No doubt. But at least, with sonars, as admitted by Tesla's chart, the car can still do Park Assist, Autopark, Summon, Smart Summon.
Without sonars, all those functions are "Coming soon."
I would think the occupancy network could be even more accurate than ultrasonic sensors as it would try to figure out the 3D position of stuff instead of whether there's something within the range of sensors. Unclear how precise Tesla will allow smart park get, but theoretically it could decide to pull over short parking stops like at superchargers while stopping before taller curbs. Maybe Tesla will allow summon for even smaller space margins than currently.
Here's Optimus Occupancy Network shown at AI Day that could be used for Autopilot pulling into garages, etc. Although unclear if the bottom visualization has limitations on what it can show to avoid visual artifacts from showing the visualized robot placeholder. Notice the closest rolling shelf utility cart has the bottom left corner disappearing:
They gave people a dongle for their cabled headphones though
They can be handy. On the other hand, I put a crease in the bumper between two sensors, neither of which detected the object. (Non-Tesla, no backup camera)
This just really ticks me off. I don’t want to lose functionality I already have in my car. And I think it is a really bad idea to gimp features in the new cars they are selling. You are making both new and old owners angry and generating ill will. This cannot be good long term for the company.

The bollard is seen but the ground is nowhere in view.
Sonar is just like a very simple ruler tape measure. You roll your ruler out and you get the distance. It emits ultrasound and it bounces back to instantly translate to distance.
It's more difficult with cameras. As you said, it can use the cues like a bollard and the ground. It has to translate pixels into meaningful objects (labeling). It's not a simple ruler. It's a very complicated computation of the pixels to get what you want: In this case, distance.
Which people complained about, lost, had to buy again, lost again, etc. My point is that eventually things settled down and now Bluetooth is the new norm. We're in the OMG phase right now - change is bad!! Let's see where things go as the tech changes and things get better.
I had made the point that Tesla was going vision-only, with exception of ultrasonic to augment the blind spots, in order to work in the driving environment designed for humans that primarily use vision. In a similar vein, Optimus is designed to work in an environment designed around the human abilities/sensors.
Now they are scrapping those.,,,
