    > "the resulting congestion required law enforcement to manually manage intersections"

    Does anyone know if a Waymo vehicle will actually respond to a LEO giving directions at a dark intersection, or if it will just disregard them in favour of treating it as a 4 way stop?

    • fc417fc802 17 hours ago
      I suddenly find that I really want an answer to this as well because I'm now imagining what might ensue if one of these attempted to board a car ferry. Typically there's a sign "turn headlights off", you're expected to maintain something like 5 mph (the flow of traffic should never stop), and you get directed by a human to cross multiple lane markings often deviating from the path that the vehicle immediately in front of you took.
      • nostrademons 4 hours ago
        Car ferries don't really make much sense in a Waymo-ubiquitous world. It's not your vehicle; there isn't really a reason why you would need to have the same vehicle on the other side of ferry ride. You're better off having one Waymo network on one side of the waterway, a separate Waymo network on the other side, and then a passenger-only ferry with a much higher passenger capacity (and oftentimes, they go much faster, since you can have hull forms like wave-piercing catamarans, hydrofoils, and hovercraft when you aren't carrying cars).
        • nullc 4 hours ago
          There are some places where a car ferry is essentially a bridge and just operate as part of the highway, e.g. there are two such instances in sacramento: https://dot.ca.gov/caltrans-near-me/district-4/d4-projects/d... The rides are about a minute long and you very much wouldn't want to change vehicles.
          • fc417fc802 3 hours ago
            Another common scenario is vastly different population density on the far side of the ferry route. It seems unlikely to me that autonomous vehicle companies would want to maintain a giant seasonal fleet at such destinations.

            In a lot of cases rather than seasonal it will be a surge every weekend.

      • voidUpdate 17 hours ago
        I think that Waymo isn't concerned about those types of scenario because they only operate in a limited area, and can tune their systems to operate best in that area (EG not worrying about car ferries, human-operated parking lots etc)
        • jvanderbot 14 hours ago
          Right. People still imagine that Level 5 is going to happen, and it is at best a long way off. You're talking full AI at some point.
    • throwaway2037 15 hours ago
      Your scenario seems to have a lot of overlap with a construction worker directing traffic around a road construction site. I have no idea if Waymo is any good at navigating these, but I am sure there is a lot of model training around these scenarios because they are common in urban driving environments.
      • voidUpdate 15 hours ago
        Don't they just have a stop/go board? Whereas an LEO at a crossing would have to use hand signals
        • bluGill 4 hours ago
          Sometimes, but not always. They may need to stop traffic for a moment to get some machine out and then there is no board. Sometimes they will tell you an alternate that is much faster than waiting as well.
    • nashashmi 17 hours ago
      This was found to be one of the early challenges of self driving: reading traffic signal gestures of traffic agents. It does it. But the jury is out if it does it well.
      • IcyWindows 1 hour ago
        It's hard for humans as well.

        I often see humans drivers being confused with the police officers gesturing more and more until the person figures it out.

    • testfrequency 13 hours ago
      The amount of times this has been asked with no confirmation leads me to believe they still do not.

      Tesla fanboys gush about how FSD can understand LEO at irregular traffic conditions, but no company I’m aware of has confirmed their systems are capable.

      • krisoft 13 hours ago
        > The amount of times this has been asked with no confirmation leads me to believe they still do not.

        They do follow hand signals from police. There are many videos documenting the behaviour. Here is one from waymo: https://waymo.com/blog/2024/03/scaling-waymo-one-safely-acro...

        Look for the embed next to the text saying “The Waymo Driver recently interpreting a police officer’s hand signals in a Los Angeles intersection.”

        Or here is a video observing the behaviour in the wild: https://youtu.be/3Qk_QhG5whw?si=GCBBNJqB22GRvxk1

        Do you want confirmation about something more specific?

        • ckemere 4 hours ago
          Is there confirm that it’s not remotely controlled at this point?
          • pastel8739 2 hours ago
            I very much doubt they would refer to that as “the Waymo Driver interpreting” the hand signals.
      • HarHarVeryFunny 13 hours ago
        Teslas currently have a driver in the front who could take over in these situations.

        Waymo said they normally handle traffic light outages as 4-way stops, but sometimes call home for help - perhaps if they detect someone in the intersection directing traffic ?

        Makes you wonder in general how these cars are designed to handle police directing traffic.

        • dham 11 hours ago
          It kind of makes sense. Why program or train on such a rare occurrence. Just send it off to a human to interpret and be done with it. If that's the case then Tesla is closer to Waymo then previously thought. Maybe even ahead.
  • nzoschke 13 hours ago
    > we are now implementing fleet-wide updates

    That ~1000 drivers on the road are all better trained on what to do in the next power outage is incredible.

    There will always be unexpected events and mistakes made on the roads. Continual improvement that is locked in algorithmically across the entire fleet is way better than any individual driver's learning / training / behaviorior changes.

    • imoverclocked 13 hours ago
      Humans seemed to navigate this just fine, even with all the Waymo road blocks and without extra training. If every unknown requires a software update, this system is doomed to repeat this behavior over and over in the long term.
      • xnx 13 hours ago
        Humans do dumb stuff like drive their cars into flowing floodwaters and they show no signs of stopping. The Waymo Driver (the name for the hardware and software stack) is getting smarter all the time.
        • flutas 4 hours ago
          as recently as 3 weeks ago, the Waymo driver was also driving into floodwaters.

          https://old.reddit.com/r/SelfDrivingCars/comments/1pem9ep/hm...

        • docjay 10 hours ago
          Humans do indeed drive into floodwaters like fools, but a critical point that’s often missed when talking about how self-driving cars will make the roads safer: you don’t. Self-driving cars can potentially be safer in general, but not necessarily for you in particular.

          Imagine I created a magic bracelet that could reduce bicycling related deaths and injuries from 130,000 a year to 70,000. A great win for humans! The catch is that everyone would need to wear it, even people that do not ride bikes, and those 70,000 deaths and injuries would be randomly distributed among the entire population. Would you wear it?

          • xnx 10 hours ago
            I don't understand the analogy. No one is being forced to stop driving and take autonomous rides. If I am a better than average driver (debatable), I'm glad to have below average drivers use autonomous vehicles instead.
            • docjay 6 hours ago
              If you’re on the road with one you’re wearing the bracelet. If you’re driving one you’re wearing two. I don’t mean to sound so sour, I was hoping the analogy would alias that into the background a bit, it’s just that the hoopla around self-driving cars is causing people to skip reading the footnotes.

              Safe vs Unsafe isn’t as simple as who gets a 10/10 on the closed course test. Humans are more predictable than random chance would allow, and often even when drunk or distracted. I can’t count how many times I’ve seen someone wobbling on the road and knew to stay back. You can also often tell when someone might yank over into your lane based on them flying up in the other lane, getting just in front of you in that lane then wiggling a bit, clearly waiting for the first chance to pull in front of you and take off. There are lots of other little ‘tells’ that, if you’re a defensive driver, have avoided countless accidents.

              Being a prudent defensive driver goes out the window when the perfect speed limit adhering driver next to you goes to straight to -NaN when someone drives past it with Christmas lights on their car, or the sun glares off oversized chrome rims, or an odd shaped vehicle doesn’t match “vehicle” in the database, or, or, or.

              * I’m very much not saying that the example I mentioned above is reason enough, I’m saying that I’m not sure enough thought is being put into how many more pages I could go on, and I’m just some schmuck that worked for some number of years on the underlying technology - not the guy watching it fail in imaginative ways on the road.

              Something said earlier that really overestimated what’s happening: it doesn’t get smarter, it gets another “if” statement.

        >seemed to navigate this just fine

        From my understanding the reason the Waymos didn't handle this was because humans were breaking traffic rules and going when they shouldn't have been. If most humans navigated it correctly, then waynos would have handled this better.

        • flutas 4 hours ago
          It's mentioned in the article, the real problem was they kept trying to contact remote support to "verify" the light was out. Leading to a backlog of requests which they couldn't get through fast enough.
        • potato3732842 10 hours ago
          This attitude is exactly how the Waymos came to handle the problem so poorly in the first place. The principal Skinner "everyone else else is wrong" bit is just icing on the cake.

          Can't just program it to be all "when confused copy others" because it will invariably violate the letter of the law and people will screech. So they pick the legally safe but obviously not effective option, have it behave like a teenager on day 1 of drivers ed and basically freeze up. Of course that most certainly does not scale whatsoever, but it covers their asses so it's what they gotta do.

          • bluGill 4 hours ago
            traffic safety engineers often have influence on the letter of the law. We would all be better off if people followed it (humans are bad judges of the exceptions)

    How is this mode not a standard part of their disaster recovery plan? Especially in sf and the bay area they need to assume an earthquake is going to take out a lot of infrastructure. Did they not take into account this would happen?
    • vlovich123 20 hours ago
      > While we successfully traversed more than 7,000 dark signals on Saturday, the outage created a concentrated spike in these requests. This created a backlog that, in some cases, led to response delays contributing to congestion on already-overwhelmed streets. We established these confirmation protocols out of an abundance of caution during our early deployment, and we are now refining them to match our current scale. While this strategy was effective during smaller outages, we are now implementing fleet-wide updates that provide the Driver with specific power outage context, allowing it to navigate more decisively.

      Sounds like it was and you’re not correctly understanding the complexity of running this at scale.

      • jeroenhd 14 hours ago
        Sounds like their disaster recovery plan was insufficient, intensified traffic jams in already congested areas because of "backlog", and is now being fixed to support the current scale.

        The fact this backlog created issues indicates that it's perhaps Waymo that doesn't understand the complexity of running at that scale, because their systems got overwhelmed.

        • vlovich123 8 hours ago
          What about San Francisco allowing a power outage of this magnitude and not being able to restore power for multiple days?

          This kind of attitude to me indicates a lack of experience building complex systems and responding to unexpected events. If they had done the opposite and been overly aggressive in letting Waymo’s manage themselves during lights that are out would you be the first in line criticizing them then for some accident happening?

          All things being considered, I’m much happier knowing Waymo is taking a conservative approach if the downside means extra momentary street congestion during a major power outage; that’s much rarer than being cavalier with fully autonomous behavior.

        • kotaKat 11 hours ago
          DR always stands for "didn't realize" in the aftermath of an event.

          That's what they're learning and fixing for in the future to give the cars more self-confidence.

        • shafyy 13 hours ago
          They probably do, they just don't give a shit. It's still the "move fast and break things" mindset. Internalize profits but externalize failures to be carried by the public. Will there be legal consequences for Waymo (i.e. fines?) for this? Probably not...
          • browningstreet 12 hours ago
            What Waymo profits?

            They're one-of-one still. Having ridden in a Waymo many times, there's very little "move fast and break things" leaking in the experience.

            They can simulate power outages as much as they want (testing) but the production break had some surprises. This is a technical forum.. most of us have been there.. bad things happened, plans weren't sufficient, we can measure their response on the next iteration in terms of how they respond to production insufficiencies in the next event.

            Also, culturally speaking, "they suck" isn't really a working response to an RCA.

          • atherton94027 12 hours ago
            Waymo cars have been proven safer than human drivers in California. At the same time, 40k people die each year in the US in car accidents caused by human drivers.

            I'm very happy they're moving fast so hopefully fewer people die in the future

    • Animats 19 hours ago
      If the onboard software has detected an unusual situation it doesn't understand, moving may be a bad idea. Possible problems requiring a management decision include flooding, fires, earthquakes, riots, street parties, power outages, building collapses... Handling all that onboard is tough. For different situations, a nearby "safe place" to stop varies. The control center doesn't do remote driving, says Waymo. They provide hints, probably along the lines of "back out, turn around, and get out of this area", or "clear the intersection, then stop and unload your passenger".

      Waymo didn't give much info. For example, is loss of contact with the control center a stop condition? After some number of seconds, probably. A car contacting the control center for assistance and not getting an answer is probably a stop condition. Apparently here they overloaded the control center. That's an indication that this really is automated. There's not one person per car back at HQ; probably far fewer than that. That's good for scaling.

      • michaelt 12 hours ago
        > For example, is loss of contact with the control center a stop condition?

        Almost certainly no - you don’t want the vehicle to enter a tunnel, then stop half way through due to a lack of cell signal.

        Rather, areas where signal dropouts are common would be made into no-go areas for route planning purposes.

      • jeroenhd 14 hours ago
        Road casualties are tied to geographical areas and America is an infamously dangerous place to live in when it comes to traffic. By fixing education, road design, and other factors, those 40k killed can be reduced by seven times before you even need to bother with automation. There's a human driver problem, but it's much smaller than the American driver problem.

        Also, that still doesn't excuse Waymo blocking roads. These are two different, independent problems. More people die in care crashes than they do in plane crashes but that doesn't mean we should be replacing all cars by planes either.

          1. [citation needed]

          2. Just because it's theoretically possible, doesn't mean it's an option that actually exists. I'm sure you can dream up of some plan for a futuristic utopia where everybody lives in a 15 minute city, no private cars are needed, and the whole transportation system is net zero, but that doesn't mean it's a realistic option that'll actually get implemented in the US, nor does it mean that we we should reject hybrid or EVs on the basis that they're worse than the utopian solution, even though they're better than the status quo of conventional ICE cars.

            > 2. Just because it's theoretically possible, doesn't mean it's an option that actually exists.

            Denmark exists. I've been there. There were cars.

            I think the west in general is lagging behind when it comes to EV adoption (and given the politico-corporate interests of many governments, I don't expect that to change). I don't think anybody wants to completely abolish cars in general and I think the drive to maintain ICE cars with all of their downsides just to support a fledgling industry is a ridiculous waste of taxpayer money.

        • mensetmanusman 13 hours ago
          Exactly, I tell people every order of magnitude more we spend on infrastructure reduces the self driving complexity as much likewise.

          The education bit can’t be fixed by the government though in the short term, as the outcomes correlate too strongly with stable home life conditions (which are in free fall over the past 50 years).

          • mrguyorama 11 hours ago
            And also because America has an extremely strong anti-education demographic that is very well represented in congress and presidents.

            "Parental authority" should not be an educational goal.

      • idle_zealot 4 hours ago
        To adapt this to a tech-head mindset:

        Imagine that when smartphones were first coming out they could only function with recent battery-tech breakthroughs. Mass-adoptions was pretty quick, but there was scattered reporting that a host of usage patterns could cause the battery to heat up and explode, injuring or killing the user and everyone in a 5-10ft radius.

        Now, the smartphone is a pretty darn useful device and rapidly changes how lots of businesses, physical and digital, operate. Some are pushing for bans on public usage of this new battery technology until significant safety improvements can be made. Others argue that it's too late, we're too dependent on smartphones and banning their public use would cause more harm than good. Random explosions continue for decades. The batteries become safer, but also smartphone adoption reaches saturation. 40,000 people die in random smartphone explosions every year in the US.

        The spontaneous explosions become so common and normalized that just about everyone knows someone who got caught up in one, a dead friend of a friend, at least. The prevailing attitude is that more education about what settings on a phone shouldn't be turned on together is the only solution. If only people would remember, consistently, every time, to turn on airplane mode before putting the phone in a pocket. Every death is the fault of someone not paying sufficient attention and noticing that the way they were sitting was pressing the camera button through their pants. Every phone user knows that that sort of recklessness can cause the phone to explode!

        You as an engineer know how people interact with the software you deploy, right? You know that regardless of education, a significant portion of your users are going to misunderstand how to do something, get themselves in a weird state, tap without thinking. What if every instance in your logs of a user doing something strange or thoughtless was correlated with the potential for injury? You'd pull your software from the market, right? Not auto-makers. They fundamentally cannot reckon with the fact that mass adoption of their product means mass death. Institutionally incapable.

        The only responsible thing to do is to limit automobile use to those with extensive training and greatly reduce volume. The US needs blue collar jobs anyway, so why not start up some wide-scale mass-transit projects? It's all a matter of political will, of believing that positive change is possible, and that's sorely lacking.

        Seriously. People are outraged about the theoretical potential for human harm while there is a god damn constant death rate here that is 4x higher than every other western country.

        I mean really. I’m a self driving skeptic exactly because our roads are inherently dangerous. I’ve been outraged at Cruise and Tesla for hiding their safety shortcomings and acting in bad faith.

        Everything I’ve seen from Waymo has been exceptional… and I literally live in a damn neighborhood that lost power, and saw multiple stopped Waymos in the street.

        They failed-safe, not perfect, definitely needs improvement, but safe. At the same time we have video of a Tesla blowing through a blacked out intersection, and I saw a damn Muni bus do the same thing, as well as a least a dozen cars do the same damn thing.

        People need to be at least somewhat consistent in their arguments.

        • paddleon 17 hours ago
          Hey, I hear you. And I'm sad. Because I'd like to say that the right way is to:

          build infrastructure that promotes safe driving, and

          train drivers to show respect for other people on the road

          However, those are both non-starters in the US. So your answer, which comes down to "at least self-driving is better than those damn people" might be the one that actually works.

          • citrin_ru 14 hours ago
            I've spend some time driving in both the US and the UK and while infrastructure in the US could be improved I don't think that's the main issue.

            What's different is driver training and attitude. Passing a driving test in the US is too easy to encourage new drivers to learn to drive. And an average American driver shows less respect to pedestrians, cyclists and other drivers, aggressive driving is relatively common. Bad drivers can be encountered in the UK of course but on average British drive better.

            Huge SUV and pickup trucks are also part of the problem - they are more dangerous for everyone except people in such vehicle.

          • pastel8739 2 hours ago
            Yes, this is really it for me. Self-driving isn’t the best solution, but the real solution requires lots of politics and lots of time to build. Tech is the one thing we are pretty good at in this country, and feels like the one thing that makes it possible to have change quickly and without endless politicking.

              However, I used to live in a place where every local driver did an 'after you' that included pedestrians, regardless of road rules, and generally drove the speed limit (and usually less).

              No, what they really mean is "a subset of typically rich typically western europe that I can cherry pick to prove my point" though anywhere formerly colonized by a European power and any developed nation in Asia is fair game depending on context.

              Notice eastern europe is nearly always left out of social issue discussions.

              Some Mediterranean bordering nations are always left out of government efficacy discussions.

              It's not about comparing like-ish for like-ish. It's about finding a plausibly deniable way to frame the issue so that the US gets kneecapped by the inclusion of West Virginia or 'bama New Mexico or Chicago or whatever else it is that is an outlier and tanks its numbers while the thing on the other side of the comparison exempts that analogue entirely and this makes whatever policy position the person doing the framing is advocating for look good.

              You see this slight of hand up and down and left and right across every possible topic of discussion in communities composed of american demographics that generally look towards Europe for solutions for things.

            I thought the UK ranked well, I didn't realise it ranked that well.

            Maybe there's something to be said for left-hand driving, I see Japan ranks very highly too. ;)

            The real reason is I guess we take road safety seriously, we have strict drink-driving laws, and our driving test is genuinely difficult to pass.

            I seem to remember road safety also featuring prominently throughout the primary national curriculum.

            And of course, our infamous safety adverts that you never quite forget, such as: https://www.youtube.com/watch?v=mKHY69AFstE

              Is this written in jest, or is there something more serious behind it? Off the top of my head, I cannot think of an obvious reason why "road handedness" (left vs right) would matter for road safety. Could it something about more people are right-handed so there is some 2nd order safety effect that I am overlooking?
              • tzs 11 hours ago
                Their comment was in jest, but I've wondered before if left vs right hand driving could affect safety. As you note right-handed people are more common. The countries with the highest percentages of left-handed people are around 12-13%.

                In countries that drive on the right then drivers use their dominant hand for any controls that are on the inward side and their other hand for the control that are on the outward side of the driver.

                Generally that means that the non-dominant hand handles exterior lighting, turn signals, windows, and locks. The dominant hand handles windshield wipers, transmission, and anything on the center console such as the climate and entertainment systems, and often also the navigation system.

                In left drive counties that is mostly reversed for right-handed people, with the possible exception of the exterior lighting, turn signals, and windshield wipers. Those exceptions are the controls that are usually on stalks attached to the steering column. From what I've read sometimes manufactures use the same stalk positions in left and right drive models instead of reversing them like they do the rest of the controls.

                Could dominant vs non-dominant hand for operating things on the center console make a difference? If everyone obeyed safety recommendations I'd expect it to not make enough difference to be noticeable, but not everyone obeys safety recommendations 100% of the time.

                If someone for example tried to type in a destination using the on-screen keyboard on the navigation system console while driving I'd expect that they would take longer to do so if they were using their non-dominant hand, so they would be distracted longer.

                  Large airplanes usually have a pilot on either side of the center console, and they AFAIK take turns operating the airplane, so if it made a difference, I'd expected it to be studied by the aerospace industry. Given that I've never seen it mentioned on any of the airplane incident reports I've read, it probably isn't a big factor, and I see no reason why it would be different for cars.

          The difference is those human-driven cars all have a driver who can be held accountable.

        My concern is that one company can have a malfunction which shuts down traffic in a city. That seems new or historically rare. I understand large scale deployment will find new system design flaws so I’m not outraged, but I do think we should consider what this means for us, if anything.

          That's hardly new. What do you think happens to traffic when a semi flips over on a busy interstate, or electricity goes out, turning all traffic lights into 4 way stops and severely limiting throughput?

          • mrguyorama 11 hours ago
            It blocks a single road and yet that makes the news and people have to route around it and it disrupts a day.

            What happens when one company's engineering failure does that to most roads?

            For reference, the US considers tactically blocking traffic to be something that smart terrorists or nation state adversaries would want to do to significantly harm the US economically.

            What do these cars do if Google's entire self driving infrastructure falls over because some component gets misconfigured? It will happen eventually.

    I suspected this. They were moving, but randomly to an observer. I’d seen about 2 out of maybe 20 stopped Waymos navigating around Arguello and Geary area in SF Saturday at 6PM. What was worse was that there was little to no connectivity service across all 3 main providers deeper in the power outage area as well - Spruce and Geary or west of Park Presidio (I have 2 phones, with Google Fi/T-Mobile, AT&T, and Verizon).
  • yonran 12 hours ago
    The blog post makes no mention of the cellular network congestion/dropped packets that affected people during the power outage. I had bars but was unable to load websites for most of the day. Were Waymos unaffected by the network problems, or were request timeouts encompassed in the word “backlog” used by the blog post?
    • AlotOfReading 11 hours ago
      The networking on AVs is usually redundant across multiple cellular networks to deal with coverage and outage issues. They also use business sims, which usually have a slightly higher network priority than consumers. If waymo's also negotiated to use one of the infrastructure QCIs instead, it would take some seriously disastrous network conditions for them to experience meaningful congestion.
      • fowl2 2 hours ago
        I wonder if the cars also have some sort of mesh (LoRaWAN?) network to help each other out in temporary dead zones, emergencies, etc.
        • AlotOfReading 1 hour ago
          Bandwidth is problematic for mesh. A remote assistance situation would involve at least 4 high definition camera streams, and ideally with minimal latency. It's challenging to put that much data onto public spectrum even if you wanted to make a custom radio.

    Sending power outage context to the vehicles does not seem like enough of a response. I hope at least they have internal plans for more. For large, complex systems, you want multiple layers of protections. The response feels way too reactive when they could use this incident to guide improvements across the board.

      People downvoting you may think that this is an uninteresting quibble: we may not find it very surprising that sometimes Waymo asks for human guidance, and we don't necessarily think "autonomous" is an all or nothing designator.
      • bgwalter 20 hours ago
        Definition in the Oxford dictionary: "Of, pertaining to, or characterized by autonomy; self-governing, independent; free of external influence or control."

        Self-driving car advertisers like Musk or Waymo just want to co-opt this term because it sounds cool. The term also deliberately hides the fact that these vehicles surveil and track you.

        EDIT: It is the full definition in the printed Shorter Oxford English Dictionary (which is a large two volume publication). It is understandable that morons downvote it.

        • ssl-3 20 hours ago
          In this context, I think I prefer to use this definition from the Oxford Advanced Learner's Dictionary: "(of a vehicle) that has the technology to drive itself without a person in control"

            But of course the advertising departments want to evoke an image of the Marlboro man saddling his horse rather than a GPS tracked, surveillance riddled, face scanning, remote assisted contraption.

        • fc417fc802 18 hours ago
          Most things aren't absolutes. This is no exception. The vehicles can operate on their own the majority of the time. That is a form of autonomy, albeit incomplete.

          You are subject to road signs, traffic, police directions, etc while driving. In the event of a natural disaster it seems feasible that you could end up in a situation where you don't know how you ought to proceed. So neither are you "free of external influence or control" in an absolute sense.

          • bgwalter 18 hours ago
            A human driver does not have to call a remote operator if the traffic lights are off.

            This situation does not require a sophistic argument that we are not autonomous because we rely on the sun. If a child walks alone to school without asking for directions, it walks autonomously. If it has to call its parents or uses a GPS phone, it is not autonomous. This is really not that hard.

            • ssl-3 17 hours ago
              A child only knows the way to school because outside influences have previously shaped the path that they are expected to follow. They're motivated to walk there because present influences seek to enforce the necessity of accomplishing this task.

              Even the mere existence of a predetermined destination (in this instance, the location of a particular school that they did not choose themselves) is influential to their behavior.

              If we use the definition that you're so defensively in favor of, then it is impossible for this child to be walking to school autonomously.

            • fc417fc802 17 hours ago
              Certainly. However it shouldn't be too difficult to imagine a scenario where the typical human driver would not know how to respond in a safe manner. Thus the presence of "uncertain how to respond" in a limited subset of scenarios remains consistent with the term "autonomous" as it appears in general usage.

              > If it has to call its parents or uses a GPS phone, it is not autonomous.

              You ought to be able to imagine plenty of scenarios where this would be the case (ie the child got lost) and yet clearly you still believe the child to qualify as autonomous. Analogously, the vehicles are not necessarily disqualified as being considered such despite being unable to independently navigate in some subset of scenarios.
