    I feel there is miscommunication on NOA. The feature behaves very different in the EU than in the US. In the US you have NOA with auto lane change. That system seems to work really well as the system complete decides autonomously when to move lanes. In the EU we have *always* had to confirm first and then *always*n the steering wheel and needs to complete within 5 seconds which is not needed in the US.

    When do discussed behavior is is very important to clarify if it is EU NOA or US NOA.

    Well, I guess a good case study is wherever google and lift are testing. I've heard plenty of stories of people screwing with the cars, but it has always been to try to trap them or slow them down rather than causing harm to others. I think the former will happen a LOT at the beginning and then people will move on. We'll probably see it soon with smart summon (at least in the US...in canada I suspect I'll have to be darn near touching the car to make it move)

    I think people will just step out in front of driverless cars forcing them to stop, then either leave a traffic cone there or put a piece of tape over a camera.

    Could very well be. But then they would be recorded by the cars cameras. And could be fined by the authorities for their behaviour. And hopefully that would make people stop doing this.

    You don't frequently see people just messing with traffic today, so I'm not sure why this is a concern.

    FUD/ edge cases/ interesting topic.
    I think in Elon's response to Jonas regarding Terminator cars, he alluded to the fact you could just stop them with traffic cones.
    Current drivers have to content with power outages disabling traffic signals and street lights, or ner'do wells removing stop signs. So it is a thing to design for.

    All the while being recorded ? It will just take a few arrests to stop such behavior.

    That is actually a serious crime, tampering with vehicle, along the lines of cutting brake lines.

    What makes messing with driverless cars more likely is simply that there is nobody in the car to take unexpected action such as catching them. Putting a bit of tape over a camera in order to disable it moving is really not in the same category as cutting brake lines.

    The 5 second thing makes NoA almost entirely useless outside of the US.

    In busy traffic, 5 seconds is simply not enough time to signal the intent, and complete the manoeuvre. The most dangerous part of the 5 second rule is that it will abort the lane change even if it has already started - but not completed - the lane change.

    Well - not really... a lot of the time you're relying on the indicator to signal intent to other drivers because you need them to leave you a space. That will often take more than 3-5 seconds. There are plenty of situations whereby you'd almost never be able to change lanes if you waited for a natural gap large enough for NoA to signal, and maneuverer.

    AP1/EyeQ3 doesn't use a neural network to perform image recognition. It does use custom ASICs to accelerate the traditional computer vision algorithms used. EyeQ3 "recognises" much more than AP2, although Tesla did not use all the features in AP1. This includes traffic lights, potholes/debris, quite an impressive array of international signage, animals (yes), and more. And, it does it in something like 3 watts, on a SoC that sits on your windshield, and since 2014.

    There is no real need to use a NN for the kinds of image recognition that Tesla is using for AP2. I can see why Tesla went down the AP2 route, and the NN route (quick, yet inaccurate results). It's not particularly great progress, overall - and it's a shame that we'll never see what a Tesla/EyeQ4 system would have been capable of.

    One of the worst things are the autowipers, really . They still don't work. "Traditional" computer vision would have worked a lot better, let alone a rain sensor.

    I'm not seeing a disagreement between our two statements.
    I was replying to the post which indicated that NoA signals, waits for a spot, then changes lanes. So the existing software could do the same for a user initiated lane change (for regions that do not require auto lane change to complete in 5 seconds, which seems to be the base issue).

    Wipers work great for me. And have for awhile now.

    Yeah so I've heard from a small subset of random people. It's far from consistent. I guess you live in a place with perfect raindrops and perfect lightning conditions. It wipes like crazy on dry windshield in tunnels tho.

    I’m not sure that’s accurate or fair at all. I’ve heard from many in different locales that it’s working well for them.
    We definitely have the same random rain drops as everyone else with variable lighting.

    I'm 100% sure it's accurate and fair. Anecdotal evidence :) So we're on equal grounds here.

    Clearly not since the behavior is different. Unless my car is broken? Depending where you are in the world, the sun rises and sets at different angles.

    Wipers seem to work well during the day in good lighting. They are not effective at night with poor lighting.

    Your wipers work fine at night? That is where mine have been useless in the past. Granted, it hasn’t rained here in a few software updates, so I don’t know if that has improved. Good news if it has tho.

    Works well at night for me. The only times I’ve recently pushed the wiper button on left stalk was with a very light mist just starting. And even then it was once.

    Fair enough. You’re correct.
