Can this be solved with just cameras, or would this need additional hardware? I know they removed LIDAR, but thought that would only be effective short range, and would not be too helpful at 65 km/h.

TIL Mark Rober is a domestic terrorist
I tried Waymo when I was visiting LA a few months ago. Genuinely terrific stuff.
I do not trust Teslas one bit though.
Tesla doesn't use lidar for its sensing, living on the prayer that AI will just get good enough soon enough. Absolutely galaxy brained decision.
waymo's have almost hit me like three times, and if i were slower, they would have. you are part of the problem. those are killing machines.
I'm surrounded by waymos every time I go out and I can tell you that if they "almost hit you" three times then that's very likely a you problem -- and a reason for more waymos, not fewer.
Anecdotally, only once have I been in a situation where I've said, "do better, robot" because I was slightly inconvenienced by it.
By the numbers there are very few waymo incidents compared to human drivers and those include waymos being hit by bicyclists who aren't paying attention.

Im glad Luigi & Wile are on the same side.
OMFG someone test to see if Teslas stop to eat free bird seed.
It got fucking wile e coyoted
The scientists in Ireland calling their data set to prevent this exact fucking thing "Coyote" sent me over the moon.
I saw the video pop up in my Youtube recommended, but didn't bother watching because I just assumed that any cars tested would be using LIDAR and thus would ignore the fake road just fine. I had no idea Tesla a) was still using basic cameras for this and b) actually had sophisticated enough "self driving" capabilities that this could be tested on them safely.
They are not still using cameras but removed LIDAR and radar from their cars during the chip shortage 2020/21. The story they were telling was "humans don't have LIDAR but can drive cars as well, so the cars also only need 'eyes' like humans".
Small correction here: they never had LIDAR. Cars with LIDAR have big racks on top with a spinny thing measuring the surroundings. Teslas had radar but removed during the chip shortage (and disabled it on existing cars) and acted like it was an improvement. The radar was used for distance keeping on cars and could actually detect the car in front of the car by bouncing signals off the ground, it was really slick.

Humans cannot, in fact, drive cars well. Humans kill tens of thousands of other humans with cars every year in the US alone.
Yup, cameras and humans share various exploits. Self-driving is going to work better than humans once every car has it and communicates with each other, allowing for minimal gaps even at high speeds, once roads are all very standardized and in a database, and-
Wait, that's trains
Fucking build more electrified high-speed rail and forget tech bros' shitty promises
I was getting mildly outraged and ready to comment how you were re-deriving the train at first. Well played.

And the really dumb thing is that lots of modern non-selfdriving cars now have lidar sensors to help the humans not crash into things. Musk apparently wants the AI to be working at a disadvantage.

That statement of him is not entirely wrong. But we humans have a very powerful bio computer that is perfectly tuned to process those visual inputs in realtime. Until a comparable performance is possible, removing LIDAR is very stupid.
Besides that, in the fog and rain tests a human likely would have killed a kid anyway, and why settle for human limitations when you could be safer?
We absolutely should also have lidar or analogous tech as part of a solution here, even if cameras did manage to get to human level safety.

And let me just add, Musk ordered the LIDAR removed against the engineers better judgement.
Did he have lidar removed? I thought it was radar. I didn't think any Tesla vehicle ever took on the cost of lidar.
This is true. There never was LIDAR.

They tested a LiDAR rigged car, and it stopped just like you predicted. As of 2021, Tesla uses only cameras for FSD, and not even radar (which my stupid fine Toyota truck has).
They tested the idea safely by building the wall out of styrofoam, or at least that's what it looks like when it blows apart :)
Front-facing radar is the bare minimum needed to pass the test given (fake-road wall). Many vehicles use it for adaptive cruise control, and radar is even faster than either cameras or lidar for figuring out the range to an object. 1000 Hz measuring distance to an object is enough to find both the relative velocity and the acceleration of another object. This provides enough time to apply the brakes safely when approaching a vehicle or obstacle
LIDAR is even better, and also more compute intensive and expensive to install.
I think Tesla was very short-sighted in removing radar sensors, certainly. If they hadn’t, they could’ve spent more of their energy on making the FSD cars better instead of just making them sufficiently safe with insufficient sensors

Clearly we don't need lidar!

I am a bit disappointed to not see the Tesla crash into a real wall. I feel a bit click baited here.
Also, they prepared the polystyrene wall to break this cartoonishly, but still played on being surprised.
The purpose of the video is to test a hypothesis, not to total a car.
Mark Rober is a youtuber sure, and some of the stuff he does is to feed the algorithm. But he's also an engineer, and that involves experimentation and a good dose of science.
Engineers won't set up tests that intentionally destroy their expensive test equipment if they can conduct an equivalent test non-destructively.
Did anyone seriously expect it to be a real wall with Rober sitting in the driver's seat?
I was expecting they'd rig it with a dummy sitting
Apparently, yes.
Is such depressing cynicism fun for you?
