  • The whole idea is they should be safer than us at driving. It only takes fog (or a painted wall) to conclude that won’t be achieved with cameras only.

    Well, I do still think that cameras could reach “superhuman” levels of safety.
    (very dense) Fog makes the cameras useless, A self driving car would have to slow way down / shut itself off. If they are part of a variety of inputs they drop out as well, reducing the available information. How would you handle that then? If that would have to drop out/slow down as much, you gain nothing again /e: my original interpretation is obviously wrong, you get the additional information whenever the environment permits.
    And for the painted wall. Cameras should be able to detect that. It’s just that Tesla presumably hasn’t implemented defenses against active attacks yet.

    You had a lot of hands in this paragraph. 😀
    I like to keep spares on me.

    I’m exceptionally doubtful that the related costs were anywhere near this number.

    cost has been developing rapidly. Pretty sure several years ago (about when tesla first started announcing to be ready in a year or two) it was in the tens of thousands. But you’re right, more current estimations seem to be more in the range of $500-2000 per unit, and 0-4 units per car.

    it’s inconceivable to me that cameras only could ever be as safe as having a variety of inputs.
    Well, diverse sensors always reduce the chance of confident misinterpretation.
    But they also mean you can’t “do one thing, and do it well”, as now you have to do 2-4 things (camera, lidar, radar, sonar) well. If one were to get to the point where you have either one really good data-source, or four really shitty ones, it becomes conceivable to me.

    From what I remember there is distressingly little oversight for allowing self-driving-cars on the road, as long as the Company is willing to be on the hook for accidents.



  • They do.

    But “all self driving cars” are practically only from waymo.
    Level 4 Autonomy is the point at which it’s not required that a human can intercede at any moment, and as such has to be actively paying attention and be sober.
    Tesla is not there yet.

    On the other hand, this is an active attack against the technology.
    Mirrors or any super-absorber (possibly vantablack or similar) would fuck up LIDAR. Which is a good reason for diversifying the Sensors.

    On the other hand I can understand Tesla going “Humans use visible light only, in principle that has to be sufficient for a self driving car as well”, because, in principle I agree. In practice… well, while this seems much more click-bait than an actual issue for a self-driving taxi, diversifying your Input chain makes a lot of sense in my book. On the other hand, if it would cost me 20k more down the road, and Cameras would reach the same safety, I’d be a bit pissed.


  • We can reliably screen for HIV (all blood donations are) why the fuck are homosexuals discriminated against over this.

    except that the tests are (per cdc) up to 90 days late in detection. So you may get infected and spend 3 months testing negative.

    And judging by OPs being german, where the rule (admittedly only since 2021) is “you may only have fucked one guy for the last 4 months”, this seems like being on the safe side, but not completely excessive to me.


  • I’ve donated plenty of times, because it makes sense that there is no other way to save lives than to donate.

    On the other hand, I’ve been wondering for years, that while I’ve been told a million times that “blood reserves are low - donate blood now!”, I’ve not ever heard that a single person died due to lack of available blood.
    Why would something like that not be reported if you want to motivate people to donate?

    My personal guess is that this comes because “lack of avaiable blood donations” isn’t a valid cause of death, the cause of death is whatever else (gun shot wound, knife severed artery / complication during surgery etc), thus it’s hard to pinpoint. Also Doctors may try to “save” blood, when they know little is available, and people may die that may have lived if they had gotten (more) blood, but also they may not have and it is hard to tell.
