Phantom Braking. It’s solved now by TeslaVision, so I know you probably rarely think about the acronym anymore.

Ah, my position on phantom braking is that I'm against it but if I'm riding in a robotaxi I prefer it to the opposite failure mode.Peanut Butter; this is a sticky business.

Aren't there ultrasonic sensors? When I get close to a curb my ultrasonic lines appear on the visualization, the closer the redder the line.Tesla is hitting curbs Iiterally because the cars can't even see them directly (it's just extrapolating like a human does). It doesn't even require advanced sensors, just something like the 360 parking cameras that have been out for ages to cover the blind areas in the front.

We started small in a limited area but very quickly you will see us expand where we are covering all of San Francisco, hundreds of vehicles out there, serving rides every night. I think that could happen as soon as the end of the year.
That's not footage from the center camera, it's some other camera he added to the car that is much wider.No, I'm assuming a known distortion camera. Outside of the camera light travels in a straight enough line.
The bollard is definitely visible to the center camera when the car hits it! The curb strikes I have seen have all been moderate speed right turns. Though many people claim it would hit them during higher speed left turns but no one seems to want to prove it.

The ultrasonic sensors are blind to curbs or low barriers that are below about 8 inches:Aren't there ultrasonic sensors? When I get close to a curb my ultrasonic lines appear on the visualization, the closer the redder the line.
Model 3 Owner's Manual | TeslaThe parking sensors may not function correctly in these situations:
...
- The object is located below approximately 8 inches (20 cm) (such as a curb or low barrier).
Given how long Cruise has tested all over SF, I would be more surprised if they can't expand city wide. I don't think it really says anything about scaling until they test in a city they have never been in before at all and see how long it takes to get everything up and running smoothly.On CNBC, Kyle Vogt said that Cruise could expand paid driverless to all of SF with hundreds of robotaxis as soon as the end the year:
Now we all know about CEO's making FSD promises. LOL. But if Cruise is able to expand city wide with hundreds of driverless robotaxi by the end of this year, that would be quite an achievement IMO. I think it would show an ability to scale.
Bummer. I wonder what my sensors are seeing when I get close to curbs. Perhaps vegetation or something just above 8 inches.The ultrasonic sensors are blind to curbs or low barriers that are below about 8 inches:

Plenty of people with curb rash or have scraped the underside of their front bumper on a concrete block to show for it, that the sensors did nothing to warn about.
Obviously. There are multiple front cameras, one is 120 degree fisheye. I assume it can see pretty close to the front of the car...That's not footage from the center camera, it's some other camera he added to the car that is much wider.
Three cameras mounted behind the windshield provide broad visibility in front of the car, and focused, long-range detection of distant objects.
Wide
120 degree fisheye lens captures traffic lights, obstacles cutting into the path of travel and objects at close range. Particularly useful in urban, low speed maneuvering.
Main
Covers a broad spectrum of use cases.
Narrow
Provides a focused, long-range view of distant features. Useful in high-speed operation.
But due to how high it is mounted and how the wide camera additionally has the entire lower part of the view blocked by the camera housing, it can't see the actual curb that is next to the car's front wheels in the actual moment (the rear facing cameras does catch the back however). It's simply not possible without a lower mounted camera. FSD just guesstimates the position of the curb relative to the car from previous frames when it is driving toward it (much like a human does), without directly seeing it in the given moment. This works ok when it is just traveling straight, but obviously has caused issues (curbing) when it makes a tighter turn.Obviously. There are multiple front cameras, one is 120 degree fisheye.

All the curb strikes I've seen have been on the back wheel where the camera can see the curb. Not sure why it matters though, I don't see how more camera angles would help because by the time the curb is out of view it seems like it would require dramatic path corrections to avoid.

It's too late by the time the back camera sees the curb, it needs to see the curb as it is heading toward it. A lower camera in the front can do that.All the curb strikes I've seen have been on the back wheel where the camera can see the curb.
Isn't the situations described of low speeds while making a turn (a bunch are at right turns in stop signs). I don't see how a low camera in front would NOT help. The car would be able to directly see where the curb is and thus avoid it. It does not need to rely on estimating it from previous frames while it is rotating the car (which is where it seems to gets things wrong).Not sure why it matters though, I don't see how more camera angles would help because by the time the curb is out of view it seems like it would require dramatic path corrections to avoid.

I'm not sure how relevant that footage is to actual curbing. The screen shot you show have the left car further away from the car, plus the hood of a car is much higher than a curb. We have no footage from the cameras when the car is making a tight right turn. I'm pretty sure in that situation the curb is pretty much going to be invisible as it is making the turn.I've seen that it is masked by the housing but haven't seen exactly how close to the front of the car. It would make sense for it to be aligned with the hood though... I'm sure those bollards were in the field of view.
Looks like it can see very close to the front of the car. Much of the other car's hood is still in view at the moment of impact.

In the screenshot the front of the Tesla is in contact with the Camry. It would be interesting to know exactly what the blindspots of the car are though. I bet it's pretty close. I guess you could put your head on the ground and pretend to be a curb and look up at the camera and housing. haha.I'm not sure how relevant that footage is to actual curbing.
