Looks like this Model S went after a Police car instead of a Firetruck?

    Merely knowing more than many, or perhaps most, others about a certain subject doesn't make me an "expert". Perhaps it just means I spend more time reading about certain subjects discussed here.

    I admit a pet peeve of mine is when someone I'm debating says that I'm claiming to be an "expert." I can tell you for a fact that I have never, ever claimed to be, nor implied than I am, an expert on any subject related to EVs or the automotive industry.

    Here's a quote from Niven's Laws:

    The only universal message in science fiction: There exist minds that think as well as you do, but differently.

    Niven's Corollary: The gene-tampered turkey you're talking to isn't necessarily one of them.
    I'm not thinking of you when I say this, David. If I'm thinking of any one person, it's a certain tinfoil-hat wearing Usual Suspect who posts comments to IEVs news articles. I don't suffer fools gladly. Just because I know more about a subject than a gene-tampered turkey, that's a very long way away from me being an "expert" on a subject!

    'Nuff said.

    Is that a message so good you post it 4 times?

    I'm pretty sure it's not every 18 seconds. ;)

    The fact that you so frequently find the need to exaggerate or state outright untruths in your criticisms of Tesla, David, shows you know your extreme anti-Tesla position isn't strong enough to stand on the facts. In short, you are a FUDster.

    And no, you don't need to "add force" to your grip on the steering wheel to let Autopilot know you've got your hands on the wheel. This is another case, David, of you cherry-picking counter-factual outlier criticisms. It's also yet one more in a long string of examples of how you are unable to stick to the truth in your criticisms of Tesla.

    To quote a recent CNN article:

    Another Twitter user wrote that the update "is a pain."

    "I now need to white knuckle death grip the wheel to keep away the nags. Don't need to keep my foot on the peddles (sic) with old school cruise control!" the tweet reads.

    Will be adjusting screen alert to clarify that we mean "slight up or downward force on the wheel", not really "hold the wheel"

    A Tesla driver doesn't need to put a white-knuckle grip on the wheel. When the "nag" warning comes, he just needs to casually move the wheel slightly, perhaps with just a couple of fingers; turn the wheel just enough to let Autopilot know "Yes, I'm paying attention, and yes, my hands are near the wheel so I can grab it if needed."

    Am I the only person who has had problems with accessing and posting to the Forum being extremely slow the past couple of days?

    Rather ironic that a message I ended with "'Nuff said" got repeated multiple times!
    o_O :p ;)

    Bottom line, Autopilot is flawed and still Beta... Supercruise works and not Beta... Look Ma, No Hands...

    We've seen that over in PriusChat from time-to-time. When it happens, we deal with it and in a couple of days someone admins it back into usable. But about cameras: https://www.stereolabs.com/zed/

    During WW-2, there were a lot of these: https://en.wikipedia.org/wiki/Coincidence_rangefinder

    Automated, 3d camera systems should work just fine. I suspect the MagicEye uses automated focus to measure distances.

    The problem isn't the hardware, it's the software.

    Just outlining the problem is sufficient for the discerning reader to have some understanding of how difficult the problem is for the software designer, and why optical object recognition software remains fundamentally unreliable:

    https://en.wikipedia.org/wiki/Outline_of_object_recognition

    Altho the hardware has limitations, too. Really, I can't understand why any attempt to develop a fully self-driving car would try to rely on camera images for anything other than reading traffic signs. Cameras have the same limitation that our eyes do about not being able to see in the dark. It seems like a no-brainer to me to use active scanning, either with lidar or high-res radar arrays, as the primary sensors. Lidar and radar work just as well in pitch darkness as bright daylight.

    Supercruise works well within its much narrower abilities. Arguably, it works better within the scope of what it attempts.

    Here's what a recent InsideEVs news article had to say on that subject:

    In the case of Autopilot, it can be engaged on a broad spectrum of roads and offers things like lane change. However, the freedom makes the system sometimes not capable of handling a certain situation (see how the Model 3 struggles on the wide lane). Anyways, Tesla cars are promised to be hardware ready for full autonomous driving and should continue to improve with new over-the-air updates.

    As for Cadillac Super Cruise, the system is very conservative and limited to only major highways, without intersections or even roadwork. Unlike Tesla, Cadillac uses eyes tracking (even with sunglasses) instead of asking you to keep your hands on the steering wheel. In effect, all you need to do is watch straight ahead and enjoy hands-free driving, which is apparently more relaxing, according to Edmunds.
