Have to say, seeing my Auto Pilot graphics with cars "jumping" all over and appearing and disappearing.. (this is not the FSD Beta graphics mind you) compared with what seems like a stable and coherent visualization of the environment, it really makes the difference in my feeling of confidence that it's aware and able to react to the same things I see around me

In reality, cars around you are blinking in and out as they jump between dimensions.

You can’t see that with your eyes because brain compensates and smoothes visual experience.

Tesla accurately represents reality.

That's part of it. Another part of it is that Tesla's computer vision is still a work in progress which introduces unnecessary jitter into the visualization. The good news is that they seem to be making improvements and the jitter is slowly going away.

It certainly does now that you’ve posted an off topic low quality comment.

> it really makes the difference in my feeling of confidence it's aware and able to react to things as a result of being aware to them.

Could you clarify? In which direction does it make a difference?

Seeing a "stable" visualization of what the car sees strengthens your confidence in its ability to perceive the world around the car.

yeah I am still confused because in the first part there's jumpy graphics and in the second part there are stable graphics, and I'm not sure if this represents a change over time, or different vehicles, or what

I believe OP is comparing the visualizations produced by the Auto Pilot system in their Tesla (jumpy) to Waymo's visualizations (stable and coherent).

Ah, okay thank you.

> this is not the FSD Beta graphics mind you

For some reason Tesla still uses old visualization software for non-FSD beta vehicles. This both means objects the system sees aren't on-screen and the interpolation algorithm for making the 3d models look smooth-moving is pretty bad.

I wonder if its possible that the FSD beta graphics use more power to render. Would be dumb to lower range on all Teslas for what is essentially eye candy. Even on FSD vehicles the visualization reverts when FSD is not engaged.

That looks like it's partly because it shows the raw LIDAR data (with some camera data mixed in I think). That's intrinsically not "jumpy" but it's also not what the car uses for driving - you have to look at the shapes on the ground.

It's kind of hard to tell, but they do seem a lot more reliable than Tesla's. Of course that's not surprising seeing as they use LIDAR.

Does anyone know if the Waymo one looks like that in real-time? It's not just nicely rendered afterwards for the video?

IIRC correctly in their Waymo videos you can see inside the cabin. Each passenger gets a video feed of that video, so I think it is real-time. Let me find a link.

EDIT: This was posted above for different reasons, but you can see the render is real-time. https://www.youtube.com/watch?v=zdKCQKBvH-A&t=401s

I've ridden in one. It's real-time.
