> Tesla will kill critical videos of FSD Examples?
The implication is that Tesla DMCAed the video in TFA. Obviously, I don't know if that is true that, 1 the video was DMCAed and 2 that Tesla sent the DMCA takedown request.

>> What if it's covered in mud, or snow? That's the entire problem. These systems don't understand anything about the world. If you see a sign covered in snow you're going to recognize it as such and make your best guess as to what it says and weather you care. You probably don't need that information to drive safely because you have a lot of knowledge to fall back on. These things dont, so some folks want to improve…
Right now, the TSLAs with FSD will disable it in snow+rain, so I assume that even if TSLA achieves L4, it will be only under ideal conditions until they have enough data to resolve these edge cases.
Maximise the video and watch the left hand HUD pane from 0:10 to 0:11. The dotted black line coming from the front of the car (which I am assuming is the intended route) quickly snaps from straight ahead, to a hair pin right, to a normal right turn. Ignoring the fact that the right turn happened to be into a pedestrian crossing with people on it - what was the car even trying to do? The sat-nav shows it should have j…
With safety systems you always want multiple levels of overlapping checks.
E.g.,
git discussion on HN: of course we all know how git leverages merkel trees to make it workable to produce millions-of-line ambitious projects across timezones with people we've never even met before (much less are willing to fool around giving repo permissions to). But goddammit it takes more than five minutes to learn the feature branch flow. That's unacceptable!
self-driving car discussion on HN: I've seen plenty of human psychopaths nearly mow down a pedestrian at an intersection so how is software doing the same thing any worse?

There are pretty stringent laws against drunk driving in most places... if Tesla's "self driving" modes are that bad then they should be equally illegal
Genuinely curious: how would you even go about advancing autonomous driving without testing it in the streets? I'm absolutely certain that they've attempted to simulate millions of hours of driving, yet this odd behavior happened in real life, which now can be studied and fixed. If we never had the software on the wild, how would you ever really test it?
The onus is on the company trying to do this to figure out a safe way.
They don't (should not) get to test in production with real innocent lives on the line just because they can't come up with a better answer.

As I understood the Tesla AI presentations the path is determined using a Monte Carlo Beamsearch which looks for a feasible path while optimizing an objective that includes minimizing sideways g-forces and keeping the paths derivatives low (smooth path). Form the videos I have seen this fails often (in that the path doesn’t go straight even if it can). Knowing a bit about randomized met heuristics myself, I am not su…

I'm actually in complete agreement! What sticks out to me is your assessment that the flight environment is "embarrassingly simple from an automation perspective", which I agree as well (as compared to cars). And yet despite that simplicity and decades at it, we still run it with an incredible robust infrastructure to have a human oversee the tech. We have super robust procedures for checking and cross-checking the a…
> we still run it with an incredible robust infrastructure to have a human oversee the tech Airplanes are responsible for 200-300+ lives at a time, so it’s quite incomparable to road vehicles. Of course it makes sense to have human oversight in case something goes wrong. On the flip side, the average car driver is not very skilled nor equipped to deal with most surprises - hence the ever present danger of road traffi…

We know how to make computers navigate maps perfectly. We don't know how to make computers see perfectly. The other uncontrollable humans on the map just make it worse.
Yes this'll not work in existing cities. That's fine. That's the point. An inscrutable black box "ML model" that can be fooled by things that humans aren't fooled by should not be in a situation where it can harm humans. I as a pedestrian did not consent to being in danger of being run over by an algorithm that nobody understands and can only tweak. Build new cities that are self-driving first or even self-driving only, where signaling is set up as I wrote in the first paragraph so that a car reliably knows where to drive and how to not drive over people. Take the opportunity to fix the other problems that old cities have like thin roads and not enough walking paths.
