    no, they aren’t. Just better than humans. (The ability to detect spoofing is probably going to be required, sadly).

    Oh, noez! Hacking might KILL someone!!!! That’s a new issue!

    Excuse me? You’re aware we have medical devices that are computerized, right? We keep electronic medical records (some of which, like allergies, could kill a patient if erased).

    Hackers being able to kill someone is nothing new. Hackers being able to kill someone with transportation is nothing new (try bollixing up air traffic control).

    This seems pretty non sequitur-ish, if only because the legal hurdles aren’t all that high, as evidenced by the absence of insurmountable hurdles for Google to get cars on the road. Yes, we will need to work out where liability lies. This is a routine question for any new technology.

    As for the trolley questions, my eyes generally glaze over when the discussion turns to this. These are questions for undergrad bull sessions, with little to no relevance to the real world. That being said, talk about the human non-driver taking over to decide who gets run over is obvious nonsense. The human non-driver is playing Candy Crush and hasn’t a clue about the situation developing. That is the whole point of the car being autonomous. I am profoundly unimpressed by any scheme for a driverless car that involves a human devoting full attention to the driving environment, hands poised to take over control in a split second. This is utopianism, and like all utopias it falls apart as soon as actual humans enter the picture.Report

        You can limit the network connectivity of cars. And also, not to put too fine a point on it, self-driving cars won’t have the largest window for hacking — users logged in and doing stupid stuff like setting their password to “admin” and telling people the answers to their secret questions and downloading attachments from dodgy emails.

        You notice one of the big hacks was attacking a car’s sensors — equivalent to shining a blinding light into the eyes of a human driver. (The computer will not, at least, panic when that happens).

        Now a self-driving car’s computers won’t be air-gapped (there’s a whole lot to be gained by allowing self-driving cars to communicate amongst themselves), and as long as there’s a communication channel there’s a method in from the outside (in addition to spoofing sensors).

        But unlike your home PC, that is a very limited channel operating with a limited format. You can firewall the heck out of that, without worry that the owner will do something stupid (like explicitly allow a virus to open giant holes in it and call all it’s friends over for some fun time).Report

Also directly network connected features of the car – OnStar, keyless entry and ignition, alarm system, wireless tire pressure sensor, in-car WiFi, GPS that downloads traffic updates, remote disablers installed by the dealership, etc. etc. etc.

            The dashboard displays speed, fuel, and engine information, so there has to be communication between dashboard and engine. It also displays the GPS map, so there has to be communication between dashboard and GPS. It also displays track and album information, so it has to communicate with the stereo. The music also pauses and lets the car stereo act as the phone speakers when a call comes in, so there has to be communication between stereo and phone. And the list goes on.Report

              There will be more processors, with much more code, communicating over fewer buses. Maintenance alone will require that the processing elements support a complex query-response model. Consider how many past security holes have been software that does something stupid with some kinds of malformed queries — that trend will continue.

              If I understand Comprehensive Experimental Analyses of Automotive Attack Surfaces right, for example, the reason your stereo’s Bluetooth connectivity has a path to control the brakes, is because there are only a few communication buses in the car, and several devices that must bridge buses.

              So you get

              Consequently, by modifying the “bridge” ECUs (either via a vulnerability or simply by reflashing them over the CAN bus as they are designed to be) an attacker can amplify an attack on one bus to gain access to components on another. Consequently, the result is that compromising any ECU with access to some CAN bus on our vehicle (e.g., the media player) is sufficient to compromise the entire vehicle

              This was from 2011, so self driving cars weren’t really in the picture yet – but that meant surprisinly little. Pretty much the only thing not computer controlled in the non-“self-driving” cars examined, were steering and the parking brake. So, they could control the fuel injection, transmission, and each wheel’s brake individually, overriding the driver’s actions.Report

            You make the mistake of thinking “communication” necessarily is “two way” communication.

            Telling my NAV system how fast I’m going does not require a response.

            Outside stuff (your phone querying your car on location) does, for instance, but the response can be highly limited.

            Designing with security in mind DOES require designing with security in mind, but even if you’re networking the car’s controller to every other bit of the car (even over Bluetooth, although why would you do that? The critical stuff will all have to be hardwired anyways) — security is easy because giant amounts of it is one way (master computer reporting to displays) and the two-way stuff should be entirely hardwired (master computer to sensors, wheel controllers, etc).

            Which is different than adding wi-fi to a toaster, because there’s not REASON to add wi-fi to a toaster, so they leave it pretty unsecured because they have no actual goal for that. “Oh maybe we’ll…tell it to do stuff later” so they leave open APIs and access and stuff.

            Whereas with a car, it’s an integral unit talking to itself — it’d be like trying to hack your hard drive by adjusting the monitor settings.

            It’s not difficult to ensure that access to the critical bits (steering,brakes,sensors) can only be done by physically accessing their controllers or master controller. Because there’s literally no reason to design it any other way.

            All the bells and whistles should be, for lack of a better term, ‘read only’. The sensors will tell your display everything they’re doing, but the display won’t — can’t — talk back. (And the sensors won’t be listening even if you tried).

            And this isn’t complicated design, really. And it doesn’t take security experts — and you can bet mass-produced self-driving cars will be built from the inside out like that, because the risks of some idiot sticking in a CD filled with a hack that has to be designed for his model car are pretty small when it’s “won’t start” but a lot bigger when it’s a car that drives itself.Report

              In an autonomous car, the NAV system will have to issue commands to the car, telling where to go, how fast, etc., so a hacker could hack the NAV system, update the maps, and tell the car to take the left turn off of Albuquerque Gorge. Of course, this assumes that the car is only listening to the NAV system, and not paying any attention to its sensor suite, which would probably note that the car has left the paved road, or that the passenger is completely oblvious and has no kill switch at his/her disposal.

              In short, a hack of a system not designed by a 5 year old would need to involve compromising multiple systems in order for it to be anything more than an annoying prank. Not impossible, but hard enough that the hacker would have to be pretty motivated.Report

                NAV system does require updates, and they probably have to be continuous updates (not the “pay 200 bucks and we’ll use a CD to update it” crap either — like regular updates, daily, automatically) so that’s a vector.

                You’d not be hacking the car, but the maps sent to it. Which requires either credential forging (“Trust me, I’m really the map update software. Here’s my totally legit certificates”) which isn’t easy or accessing it at the source.

                Map update process would be bank-level security — the usual certificate public key dance to exchange a private key, which is…difficult to break into. When banks get hacked, it’s because either people got hacked or certificate authorities got hacked. Same with a self-driving car.

                Honestly, if you could hack the update process you’d not bother with crashing cars and instead steal a whole bunch of money or otherwise commit far more impressive crimes. (Assuming car designers wrapper their map updates using the very common security solutions for financial transactions).

                Getting to the maps themselves would require hacking people, which is doable of course. I’d worry more about security on the end that generates the maps than anything else.Report

                The hacker can provide the GPS system with a map file that uses a 3000 byte NOP sled leading into some shell code at a spot where the map parsing code copies without bounds checking into a 2048 byte buffer.

                Then it really doesn’t matter than you’re on the GPS and not some other device – you have code execution, in the car, with a connection to the communication buses you need to control everything. There has been, so far, no sign that onboard systems exercise any scepticism at all with respect to signals they receive over onboard buses. They do whatever you tell them.

                The front left break is not saying “Oh, a message for me! I accept commands from only the ABS controller. Let me check the digital signature of this command to ensure I am only taking instruction from a GM-signed ABS controller firmware before I enact it.”

                It is saying “recipient bytes 07 A3 – that’s me! Command byte D2 – that’s ‘set brake pressure’, next byte is the amount. Amount byte 00 – no brake, done!”

                Did that 07 A3 D2 00 come from manufacturer-issued code running on the ABS controller, or did it come from a hacker’s shell code running on the stereo? The brake controller has no way of knowing. Every legitimate piece of control software in the car could be shouting “brake, dammit, brake hard!” but if the stereo keeps saying “stop braking” it will.Report

        Forget the trolley context, and imagine a scenario in which an autonomous vehicle is faced with a large obstacle at speed, a situation certain to cause damage and likely injury to any occupants of the automated car. What does it do: slam on the brakes and strike the obstacle at the lowest speed possible? Swerve to the left into oncoming traffic? Swerve to the right off of a steep embankment?

          I’d find those questions a lot more interesting in the context of autonomous cars if I thought there was some reason to believe that human drivers were already doing a bang-up job of handling those no-win situations. I strongly suspect that they are not. The most likely outcome of those rare situations seems like it’s probably the human being flailing out a bit and then saving his or her own skin. This is something an autonomous car should be able to do pretty well, and it should reduce the overall number of no-win situations while it’s at it.

          In fact, let’s assume that the car does the “morally wrong” thing (whatever that is) 100% of the time and humans get it right 50% of the time. If the car also cuts the number of times it gets into those situations by 80%, doesn’t that make the question basically moot?Report

          how will an automated driver make decisions when no good options are available, only varyingly bad ones?

          I guess my point here was that this is the wrong question. It assumes that that what we create – driverless cars driven by ‘robots’ – will be free of human error. And it will inevitably make a decision that, like all human decisions, we have to live with. Which is why the ‘who takes responsibility’ question is important – it must necessarily be the passenger who owns said car, no? But the reverse question might be insightful as well, I think: why would anybody hold a driverless car at fault if it is supposedly better than human drivers? There’s never going to be an agreement on the proposition that ‘driverless cars are better than human drivers’ and if there is, the problem of responsibility will be moot because, like the benevolent king, every decision will flow from some ‘thing’ better than us in every sense of the word. And we will be able to all nod in agreement that ‘well at least this is preferable to humans driving.’ I can imagine court cases using expert witnesses as attempting to determine what a human would do in said questionable circumstances to determine fault of the company or, as it would be, fault of no good possible outcome whatsoever.

          @chris

          I think one interesting issue this discussion raises is that SDT is going to create a distinction in the case of many car trips (including all single-occupant trips) that has never existed before between the occupant and primary controller of the AV technology, and the entity that is in direct control of its maneuvers.

          So, presumably under normal circumstances there are situations in which car occupants sue drivers of vehicles in which they rode over injuries caused by negligent driving. But presumably the bar is fairly high there, because there is an element of consent in choosing to ride with someone. And of course, drivers don’t get sued after accidents by people in their vehicle unless they have passengers with them at the time of the accident.

          The question will be, when you get into an AV alone and instruct it to go, will you be assuming the legal position of someone who is riding in a normal vehicle with a driver of X degree of skill & responsibility – or perhaps accepting just a bit more responsibility because the consent you have given will be spelled out somewhere and be even more thorough than that implied by getting in a car with another driver? Or by being the human who is directing the AV to operate, are you not just consenting to assume the risk of being a passenger, but instead retaining some (perhaps large) portion of the responsibility for the operation of the vehicle, as if you were still the driver to some degree?

          As you say, these questions will have to be worked out by lawyers and firms developing the technology, and very likely is being worked out (or at least worked on) right now.

          Shorter: it’s never been the case before that you’ve had solo occupants of vehicles suing the driver of a vehicle they were riding in (and driving) when they were injured due to accident. Because, same person. Nor have you often had, for example, kids or wives suing the operators of vehicles in which they were injured when the operators were their dads or husbands. Because, Dad. But now there could be people to sue in those circumstances. So that could cause some weirdness for a while, unless it’s all nipped in the bud by explicit liability limitation. (But even then, lawyers make their $ by getting around those kinds of provisions.)Report

      That’s the real issue: a lot of people don’t really think about there being multiple levels of “insecure” that are relevant in different situations. Just about everything is breakable given enough effort. The cheap Kwickset lock on a front door can be picked in seconds by anybody with a few hours’ practice. Barring that, it’s easy to break a window. But locking your doors and windows deters most casual theft and keeps the house reasonably secure.

      Yes, digital security has a new tier of “insecure” that physical security doesn’t have: The remotely exploitable hole that makes it possible for one guy to break into every house in the US while eating a sandwich. We see that failure mode on stuff like web servers and Internet enabled nanny cams, but I don’t think we’ve seen it with car electronics, and it should be avoidable given good design practices. The problem is that that’s the failure mode everybody assumes is happening when a news report says a system was broken.

      Giving a hacker the ability to crash every car in the US from his cell phone is very different from the types of car security flaws that usually make headlines. Typically the “hack” is, “Somebody gets into your car and connects a custom-built physical device to the OBD-II harness that injects bad stuff on the CAN bus.” OK, fine. That’s a real problem that we should mitigate. But it’s not the end of the world. It’s analogous to saying, “Given a few minutes of access, somebody can cut your brake lines.”Report

    Including but not limited to such questions as:

    – Is SDT, for all the talk, per Atrios, really going to turn out to be a non-starter in the U.S.?

    – To what extent will/would SDT shrink the number of surface shipping driver jobs assuming the above is not the case?

    – To what extent will the gains in road safety (fewer injuries, deaths, lower costs) be realized?

    – How much of a time-saving technology will SDT turn out to be in practice? Will we all (those of us who manage to adopt SDT) get more sleep than before? Get more reading done? Time with kids improved due to full engagement? Get more work done? Etc.

    – Will employers capture a large share of the driving time that’s saved, making the time savings not a valuable reason to pursue SDT? (To me this is a much broader social question, so that applying the argument to this one particular case and accepting it would imply a conclusion that we should basically just abandon all time-saving or even just all new technologies of any kind. (The author cites email and smart phones as examples of where this has happened with other technologies, but to my recollection neither of those technologies were much heralded as potential time-savers, but much more as capability-enhancers, and ones largely developed and pioneered explicitly (though not exclusively) for the purpose of making people more productive in their work. SDT to my understanding isn’t presented as having that intended application.)

      I Could Be Wrong On The Internet
      It wouldn’t be the first time. But the reason I harp on what I consider to be the ridiculousness of self-driving cars is that I think the only way they’ll “work” (and even then, not well enough) in my lifetime is if an absurd amount of money is spent on building public infrastructure to make them work, instead of building more sensible things like mass transit. I also don’t buy the various pro-urbanism arguments for them, which amount to “we won’t need urban parking lots or to own cars” because you still have the commute problem. In a car-centric world, you have to have enough cars so people can go to work by car if you don’t have that lovely mass transit system.

      If they really do work as promised without upgrading the technology of our entire road network, maybe that would be a good thing. I just don’t believe they’ll work well enough. Of course in the future we might all upload our brains into robot bodies and finally get our jetpacks. When I say it won’t work, I mean it won’t work in anything resembling the timeline that boosters say it will. I don’t think it’ll work in my lifetime, and I plan to live at least a few more years.

        Go read my post on SDT again. Yes, there will need to be infrastructure upgrades, but they can be minor.

        As for public transit, I will say this again because public transit hardliners always seem to handwave this away – public transit fails at the margins, and as long as it does, it will always be a second fiddle to cars, either POVs, or public Autonomous Vehicles (AV). Mass public transit is great for getting people from area A to area B, and in most cases that is sufficient. For the regular daily commute or casual user, those people can walk the last bit to their destination.

        It fails when it can’t get close enough* so the walk is more than people want to deal with, or when people are moving items that are heavy/bulky/difficult to carry, or managing infants/children, or are disabled, etc. Now of course, people figure out ways to do such things on public transit, but those are people who either really love public transit, or have no choice. Since the funding for public transit is largely approved by people (i.e. middle class and above voters) who are not interested in having their choices deliberately constrained in order to satisfy a minority of advocates, it will be a problem for the long term until those advocates start treating those margins seriously.

        Now, an urban system where extensive mass transit can largely meet the needs of the volume of arterial highway traffic, then you can do things like replace highway lanes with rail lines and we don’t need AV to get from home to work, but we will still need cars to get from the house to the rail station near home, and from the rail station near work to the office, or store, etc. And occasionally a person will need a car/van/truck to handle a task that just can not be done on public transit.

        For those margins, a fleet of on-call AVs, that can be called upon in a moment, or booked in advance, will be instrumental in making the rest of the transit system appealing, and that fleet can be relatively small and can utilize automated parking garages to reduce the space requirements for parking, since once a car drops a person off, it goes to get another rider somewhere, or reports back to the garage for charging or maintenance or idle time.

        *Often, mass transit can get you ‘close enough’, but the path to getting ‘close enough’ has to be convenient. If getting close enough involves multiple transfers, especially if taking those transfers involve lots of waiting or riding longer distances than necessary, then the convenience factors falls off quickly for people who are time sensitive.Report

I said responses to any questions raised in that thread were welcome, but the preference for mass transit wasn’t even one that I listed as of particular interest to me. I don’t have any position on that. I didn’t mean to say I agree with Atrios about his preference for mass transit over AVs; I was just saying that I’m skeptical we’re going to see a big influx (I gave a number) of them into the general fleet in our lifetimes.

            Thing is, AVs have challenges facing them, but critics (and advocates) tend to focus on the wrong challenges as being key. The control technology is already here, the infrastructure upgrades would be minor and can be phased in gradually (and will certainly cost less that tearing up a road and replacing it with rail), & affordable sensor suites are easily within sight; the hurdles are learning AI (software) & security (what @morat20, @dragonfrog, & I were discussing elsewhere).

            The one thing Atrios said that is probably correct is that such technology will be readily adopted elsewhere first, before finding a home in the US.

            Anyway, I’ve seen that attitude about AVs from transit advocates before, where AVs are dismissed or trashed because it doesn’t gel with their grand vision for public transit. Where that last mile concern is hand waved away or ‘solved’ via walking, or bicycles, or some other solution that would be great for them, but ignores the needs or preferences of anyone not like them.

              Small electric cars, including autonomous ones, are large-scale compliments to other transit only if you assume the suburbs, both housing and the jobs, continue. That assumption is anathema to many (most?) public transit advocates. I’ve usually summed up their strategic plan as “If we can just make the suburbs as unpleasant as we’ve always claimed they are, people will move back into the cities.” This is not, IMO, a particularly good plan.

              Just on the basis of energy considerations, the suburbs are going to change over the next 30-50 years. That’s not the same as “go away”.Report

Then again, I know logistics experts, so they come up with fun things like “Let’s have gondolas! It’s cheaper than building another road!”(and way more fun, bonus!).Report

      Is SDT, for all the talk, per Atrios, really going to turn out to be a non-starter in the U.S.?

      I think it will start in niche markets. Long-haul trucking is the one that gets mentioned most often. Another likely one is the elderly. They want to stay in their own homes, and keeping them in their own homes is much less expensive than institutions. SDT is potentially an important piece of allowing more of them to stay in their homes longer.Report

      No. Uber is betting on it, and they’ve got real reason to want their human employees gone as soon as possible.

      – To what extent will/would SDT shrink the number of surface shipping driver jobs assuming the above is not the case?

      A LOT, but look for a graduated phase-in, and dwindling of money paid before dwindling of people hired.
      1) Expect main routes to be mapped and used first
      2) Expect SDT to become mandatory for certain times of day (thus extending the driving time to 24 hours)
      3) Expect SDT to make long-haul driving into less of a “hazard pay” and more of a “slight amount of supervision” job.
      I know someone who’s designed SDT, so…

      – To what extent will the gains in road safety (fewer injuries, deaths, lower costs) be realized?

      Nearly 100%. This will work, once the legal stuff gets busted through.Report

      A. It gets drunks home from bars and the elderly around town.
      B. The crashes will be at low speed and in a low weight vehicle.
      C. If the machine gets confused it can relatively easily find a shoulder and stop.
      D. The capital cost should be pretty low.

          I think that early roll-out days will inevitably have some bugs. I’d much rather have first adopters (and the people around them) being in a quiet light-weight oversized golf cart going 30 in the suburbs than an 18-wheeler getting confused doing 70 on the I-5.

          For myself, there are any number of restaurants my wife and I don’t go to, because I don’t want to deal with the drive getting home. (I’ll be signing up for Uber any day now.) But it would be really kinda cool to participate in the roll-out of truly revolutionary technology.

          So if I were Alphabet and Uber and GM and Solar City and Enterprise Car Rental, I’d be forming a JV which (a) sublease land in Enterprise parking lots, (b) installs solar cells in pop-up frames that cover the parking lot, (c) places an Uber employee in the office to plug in the cars day and night, (d) leases NEVs from GM, (e) leases the self-drive tech from Alphabet, (f) contracts with the City (of Venice, CA, for example) to use street-side and muni. lot parking so the car doesn’t have to drive itself back to the lot after every trip; and (g) puts an Uber driver in each car for at least the first six months to a year, or until people calling for the car want the discount price that excludes the driver.Report

      – To what extent will/would SDT shrink the number of surface shipping driver jobs assuming the above is not the case?

      You mean my job? Short answer: some, not all, and not all at once.

      Longer answer: Driving, per se, is only part of my job. There’s also pre- and post-trip equipment inspections, fueling, loading and unloading, and connecting/disconnecting trailers to/from tractors. And that’s just assuming the trailer is your basic box on wheels. Flat bed work also entails load securement with straps and/or chains plus tarping. And you can’t just strap and tarp and drive; the load can settle or shift causing the chains or straps to loosen, tarps can become discombobulated, and so you’re constantly monitoring that in your mirrors and periodically stopping to check and adjust it all. Then there’s tankers hauling various liquids from milk to truly ghastly chemicals, pneumatics, end dumps, and belt bottoms hauling dry bulk stuff, car haulers, etc. These all entail essential activities well beyond just driving.

      Seriously, driving down the road is the easy part of my job. And of the non-driving stuff only a fraction can be automated, eliminated, or off-loaded to someone other than an onboard operator. And doing so will in many cases require significant alteration of processes, practices, and facilities, as well as g-d only knows how many trailers of various kinds.

      So what’s the upside? In a word, productivity. Truck drivers are legally and practically limited by Hours-of-Service rules and human endurance to about a 50% duty cycle at best. I would estimate that, as an Over-the-road driver, somewhere around 75 to 90% of my miles are on the Interstate system. For example, I just finished a run over the weekend of almost 1800 miles from the SF Bay area to Oklahoma that was entirely on interstate highways except for about a mile or so on either end. At 60 mph that’s about 30 hours of actual driving (apart from getting out of the Bay on a Friday afternoon. Yechh.). If I could just navigate to the big road, put it in full auto mode, and sleep, read, play, masturbate, etc while the truck drives itself, I could make the run in literally half the time.

      Other types of trucking work, like local delivery, would realize much less efficiency gains. There the gains would manifest more in the safety arena. For example, the most common type of trucking accident occurs when backing into a dock or parking space. A truck that could do that autonomously and safely would save the industry millions annually.

      So here’s my prediction: SDT will be, in some ways, the tip of the spear due to the economic potentials. It will be an evolutionary rather than revolutionary process due to the enormous sunk investment in the status quo. The job of truck “driver” will metamorphose into “Heavy Truck Operator” as driving, per se, becomes a smaller portion of the job and employment in the sector will gradually decrease as each truck/operator pair becomes more productive. There will be very few — if any! — trucks running around with no human on board; keep in mind, trains run on tracks and they still require operators.

      Finally, and this applies to cars as well, I predict the standard controls we have now — steering wheel, pedals, etc — will give way to something like a joystick as “driving” becomes more a matter of telling the car’s computer system where you want to go.Report

It almost seems like your job could shift to something more like a train engineer from being the moment-to-moment physical driver of the vehicle to managing the various on-board technologies that will take over that task.Report

                It’s effectively road trains — we’re talking trucks less than a foot from each other. Surprising fuel savings, you don’t need to add much to the trucks (compared to SDT) and a smaller problem set to solve (stay this distance away, and of course some method of instantly communicating speed changes — especially sudden brake applications — from the lead truck).Report

                Too-close following by too-long a convoy on the interstates creates a different problem that will have to be addressed. Someone pulls out to pass the line, and half-way through discovers that their exit is coming up right now.

                Ugh. That’s just some truck drivers being assholes. I don’t bother trying to pass another truck unless there’s no car traffic coming up behind me in the left lane and/or the guy in front of me is going considerably slower than me, which doesn’t happen much since I’m governed at 62 mph. And if I have another truck passing me slowly like that and I see traffic backing up behind him I’ll back off so he can get around faster.

                IDK, there’s some unavoidable physics that militates against those sort of following distances even with instantaneous computer reaction times. A fully loaded semi, at the current standard weight limit of 80K lbs, requires approximately a football field length — 250 – 300 m — to come to a complete stop from 60 mph under ideal conditions, exclusive of reaction time.

                If that lead truck were to suddenly encounter an obstacle, like a drunk human driver crossing the median, or have some mechanical failure… well, it might work out as long as the heaviest truck(s) are in the lead. Otherwise, boom bang boom…Report

      My two cents:

      1. Bad lane markings are not going to be a deal breaker.

      2. Given that some people currently work on mass transit or in a car while someone else drives, I have no doubt that some people will work in self-driving cars. To some extent, for some people, this may be compensated by reduced work in other settings (either shorter hours in the office or less work at home). In general, people navel gazing about changes from SDT need to spend more time looking at similar existing means of transportation.Report
