      Speaking of fire trucks has anyone here ever read the emergency response procedures for teslas in severe accidents? When I was a volunteer we gave it a look over.

      If I remember right, Depending on the model they recommend up to 8,000 gallons (~30k liters) to keep an overheating battery’s temp stable in case of fire or exposure to high heat. I’ll link the resource page here.

      Our engine holds 700 gallons (5.2k liters) and the typical tanker in our area holds 2,000 (7.5k liters)

      That’s a house fire level response for a single electric vehicle. Just getting that much water moved to a scene would be challenging. We have tankers, but how many city departments can move that much water? You don’t see hydrants on highways. And foam is not effective like it is for normal car fires. The future will be interesting for firefighters.

      It is especially important to understand that Tesla’s struggles with navigation are entirely a result of Elon refusing to equip them with LiDAR. This isn’t some “The tech is really new and really complicated and we’re still figuring it out” problem. There is a very good solution to most collision avoidance scenarios, but Elon refuses to let them use it because he’s an idiot.

    For those doing the maths at home:

    An F35 who obligingly flies top-towards-you (not exactly something you can do, but hey, maybe they’re turning) is all of 10m tall.

    An AIM-120C can very comfortably hit a target at 100km.

    At that range, the F-35 takes up 26 arcseconds, or 0.007 degrees. That’s roughly about the size of this period, at a distance of 3 meters away.

    [ . ]

    Good luck spotting that in a sky of roughly the same colour, full of other objects.

      You can place cameras anywhere, they don’t need to be right next to what is being targeted. Nearer ranges will allow AI to misidentify at much higher rates than max standoff ranges of an AIM-120C.

      Just for reference: JWST has an optical resolution of 0.07 arcseconds. It’s a mirror 22 feet in diameter though, not something you’d put inside a missile guidance package.

            Well but I am!

            Although, we would still need to get it back here… Okay so first we send two more rockets after it! One to return it on and one with the/a human engineer on board to pack it back up.

            I mean we can hardly have it return while unpacked. That would damage the delicate heat baffles! And we need those to shield it from the rockt engine at the back of our missile so it doesn’t start targeting itself because it no longer knows where it is/isn’t…

      and then also dealing with the F-35 itself, even if you managed to lock on and target it, it will have anti-warfare capabilities you have to contend with.

      Part of the reason air defences mostly rely on radar and other parts of the electromagnetic spectrum from at least 3 locations using triangulation to build a precise map of objects in the sky, but just like cameras that doesn’t work when the objects in question are too high or hidden behind objects. From there you can send countermeasures to intercept coordinates and then arm them to search for nearby objects via infrared.

      Using the visible part of the electromagnetic spectrum is pretty much useless in modern weapons. I remember seeing even a Tank operator’s display being totally jank because they don’t use normal cameras either, perhaps because they wanted data to train machines to do it instead of human operators? Idk, didn’t make sense to me.

      No no. See guessing objects from flat images is much better than using math and lidar. Especially if you may have a flawed llm model.

      Given how advanced our math and knowledge of radar is, it is literally stupid to use them.

      See, those, radar, lidar and math give you a 3d objects.

      Oh, wait. It is the other way around.

      He’s not, otherwise he would know that “low light sensitivity” cameras aren’t “sensitive in low-light conditions” but “with lower than normal light sensitivity”.

      In an imaginary world where cameras are way more expensive, he’d absolutely be pushing LiDAR in cars. The metrics he cares about are cost and marketability (cool factor), or money for short.

          It’s a simple design, like a boxcar you’d race with your dad at the local boy scouts event. It appeals to children who don’t understand how airflow works and just like seeing big bulky tank like things. To them, it looks like a Tonka toy.

          But in the real world, things like fluid dynamics are important.

      You’d need a camera network spanning the entire battlefield. And it’d need telephoto lenses at the very least, because stealth fighters are high and small. And it’d need to stay connected after an initial missile exchange.

      I don’t buy for a moment that nobody in the Pentagon has thought of this, and explained why it’s not a dealbreaker in a classified report.

        Telephoto lenses have a low field of vision. You’d want very high resolution wide angle sensors. Or maybe a combination of the two, where the wide angle cameras spot interesting things for the narrow angle ones to look closer at.

        The difference between the two would be like when they went from U2 spy planes to satellite imagery, going from thin strips of visibility to “here’s the hemisphere containing most of Russia”.

          The trick being that wide angle and high resolution means very high expense, and probably a lot of power and ruggedness tradeoffs. For a satellite that’s fine, for this application I kind of think a cluster of narrow-view cameras would be way cheaper and more practical.

        It might actually cost way more than that, changing the jet’s balance and attaching things to them requires major modifications, but him selling the the systems for that alone sounds about right.

        Maybe the real plan is to intentionally fuck it up and weaken the US Military. Wouldn’t put it past the Trump admin.
