    Decades of road simulation? Perhaps with functional programming regarding rules and 'best practices' according to the rule of law and making sure the car operates on the road as expected in ideal conditions. But there's no way to simulate the real world failures like you're asserting has been done. And certainly not for decades.

    You clearly have no idea what the state of the art actually is, where I've actually built such simulators. We've been building them for several decades (of real time) already. Yes, some algorithms (mostly for communications and basic sensors, including tire pressure) have had simulated time exceeding a hundred thousand hours, which is over a decade of continuous real testing.

    You'd be amazed what can be simulated these days. One of my colleagues works on simulators for a tire company, modeling the wear pattern and friction for their tires, to maximize the tire's handling and hydroplaning resistance throughout its life. His simulator evaluates different tread patterns and different rubber formulations against different driving styles and conditions. Fascinating stuff, and the only physical result is the confirmation tests, when the real thing is actually manufactured and driven for a few months.

    Yes, this is real life, not your if-it-ain't-broke-don't-fix-it fantasy.

    You can choose to ignore what I've written, as you've chosen to ignore the other research and progress in the field. Looking through your comment history, you seem to do that a lot. You also seem to have a bias against modern automotive safety, based on myths that have been continually disproven.

    Yes, it's true that there are faults to modern technology, especially with regards to safety equipment. However, you don't seem to understand that the risk of new technology is far less than the risk presented by older technology. A driver in a collision who has an airbag may break a collarbone, but he won't have frontal-lobe trauma as he would if he were allowed to hit the steering wheel.

    These things can (and are) tested. What's important is that the circumstances of the test be identical, so the difference in effectiveness can be measured. One good way to do that for vehicles is to take an old vehicle, and crash it into a new vehicle. That way, thanks to Newton's third law, we know the impact force is exactly identical. In fact, here's a good demonstration.

    An algorithm? Just one?

    Yes, just one algorithm. As slashping points out, it's the combination of other smaller algorithms:

    • One part is the always-on image stabilization in the vision recognition system. It finds nice reference points (buildings, lane markings, a horizon, etc) and keys those to determine the relative movement of objects in view. Moving the whole vehicle doesn't affect image recognition at all.
    • Another part goes into the handling system, to allow the vehicle to rapidly adjust its expected handling characteristics in an emergency. That also isn't really a "blowout" algorithm, as it's the same routine used for hitting ice or snow, or a deep puddle, hooking up a trailer, or any other major change that falls outside regular wear on the vehicle.
    • Yet another part of the whole algorithm is in the vehicle-to-vehicle communications routine, to announce to other vehicles and stationary beacons that the vehicle has experienced an emergency, and should be considered a risk. That's a courtesy to other vehicles, to provide redundancy and confirm their sensors. It can also begin coordinating additional help, such as a tow truck that can be coming to assist before you've even realized you're missing a tire.
    • Of course, there are also the more mundane algorithms that will have some accommodation for emergencies. Vehicle control systems handle short-term navigation, and they'll be directed to get the car off the road ASAP. Environmental controls can turn off vents to keep the smell of burning rubber out of the passenger cabin. In-car entertainment systems can present a message explaining the situation to calm passengers.

    All of those parts get bundled together into a single unit for designers to track, and it'll probably be documented somewhere as the "tire blowout algorithm".

    Lets crank it up a notch. The tire didn't blow out, but the tread separated and wrapped itself round some structure of the undercarriage and locks up the rear end. On asphalt pavement with a ton of road grit and gravel.

    Lol, now put the driverless car on a highway with thousands of other cars, fog, rain, etc... and let the fun begin.

    Put those cars on the r[o]ad and let the slaughter begin.

    Ok. Where's the hard part? What you're describing is a worst-case situation, and most of it doesn't matter. Fog and rain only affect one out of several sensors, and a road with "a ton of road grit and gravel" isn't unusual. That's expected for a road. Every time the software checks its own state, it considers the road condition. If it doesn't have "a ton of road grit and gravel", then the vehicle doesn't need to compensate for that.

    What is being built is a perfect super-human driver. It has access to senses that humans don't, never gets distracted, never panics, and never deviates from best practices. It has spent several decades of (sim) time in simulations, dealing with hundreds of thousands of hazards, and now you're worried about rain?

    Oh, I love this game! The Luddites bring it up every time autonomous cars are discussed.

    How will a computer respond to a tire blow out on the highway at 60mph plus? Some other emergency?

    Within a few milliseconds of the emergency being detected by sensors, the computer will have fully assessed the situation and determined the safest course of action. A blown tire is simple, because it only really affects the vehicle handling parameters. At over 60MPH on a highway, the vehicle is going to have very minimal handling needs. The steering system can be told (within those milliseconds) that it will need to adjust, and in a few rotations of the tire, it can analyse the shape of effects of the new tire's shape. At minimum, it will know that it needs to steer a few degrees to the side of its intended course, allowing it to stay on course and maneuver safely to the shoulder.

    How will the car that gets slammed into by an autonomous vehicle with a blown tire respond?

    If by some absurd accident that does occur, it'd be treated like any other unavoided collision. As soon as the vehicle determines that a collision is unavoidable, it will attempt to minimize the damage. There has been research into having algorithms adjust the vehicle speed to change impact position, relying on a database of the vehicle's crush characteristics to reduce the chance of injury. Results show that the computer can do that faster and more successfully than any human driver.

    How will the cars behind it react to the event in front? How fast?

    When the front car detects the blowout, or when the cars behind it detect the debris or change in driving characteristics, they will consider the car to be a risk, and avoid it. They will start slowing down, changing lanes, and otherwise avoiding the affected vehicle. Again, this has all been tested.

    As for the speed of this decision, everything happens in a few dozen milliseconds. At 60MPH highway speeds, that means that the computer will process and understand a situation before the vehicle has traveled a few feet. In comparison, a human brain reacts in about 150 to 250 ms, depending mostly on the type of stimulus. It doesn't matter how good of a driver you are, or how much attention you're paying to what's going on. An autonomous vehicle can observe, consider, and begin reacting to an emergency in front of it before your brain can even understand what your eyes are seeing.

    What will happen to the hacker that intercepted and manipulated those signals the other cars are sending to each other? ( assumption made )

    Oh, don't be so coy. You've made an awful lot of assumptions without actually understanding the current state of the art.

    Legally, probably nothing will happen to the hacker, because it'd be difficult to find and catch such an attack, but that has nothing to do with the cars. It's equally hard to find someone using a cell phone jammer today. There have been a few cases, but they were caught due to prolonged or repeated use.

    From the perspective of the cars on the road, losing communications with the other vehicles is a known and tested risk. Similarly, mismatched information is a risk condition. The easiest response is to slow down and try to move out of traffic.

    Has any of these scenarios been tested? I don't see any crushed google cars so I am going to guess NONE.

    Yes, these scenarios have been tested extensively, but you don't know about it, because you're not bothering to do research. One of the fascinating aspects of robotics research is that researchers can control all of the inputs to the algorithms. We can put a sensor in a tire, then drive it down a test track and make it blow. We can take that data, mix it with data from a dozen other test runs, and use that to build thousands of simulation input cases. Those inputs are run in simulated environments, with and without vehicle-to-vehicle

    Conspiracy theories aside, you're sorely mistaken on a few key details. Common Core is a set of concepts, and a timeline for when they should be understood.

    Common Core also has absolutely nothing to do with your decision to send your child to an out-of-district school, should you desire to do so, and it has nothing to do with the additional expenses you may incur. Instead, the extra expenses are because you are opting out of the services provided by your local government, such as buses and shared textbooks, and must then cover those costs on your own. Yes, you do still have to pay taxes to support your local school district, because that's what your duly-elected representatives have written into law, and you do still benefit from having schools. Though you say you "derive zero direct benefit" from your local school district, you do still receive an indirect benefit in the community improvement.

    Last I checked, the actual standard doesn't actually include any testing standards or teaching methods. It's really pretty loose for a standard (though my engineering bias rears its ugly head here).

    Rather, the actual standard says what concepts must be taught at what grade levels... and that's about it. There are some examples and the set of minimal facts to be understood, but it doesn't prescribe any curriculum, and it doesn't say how to evaluate students' progress toward that basic comprehension.

    It's also not a "federal standard". States are adopting it on their own, and if your state has chosen to legislate partucular testing methods to ensure compliance, that's your legislators' fault, not Common Core.

    From what I've seen (from association with a highly-regarded educator's college), Common Core is a great step forward. Previously, every state had their own standard, so a Louisiana high-school student, for (a fictitious, as I've forgotten all states' relative rankings) example, might be far behind a similar Oregon student in mathematics, but still meet their state's standards. For high-achieving students who relocated and were then told that their education wasn't good enough for their new location, it was devastating. For students transferring the other way, they'd often end up skipping grades, leaving holes in their understanding that wouldn't appear until later, when the curriculum assumes a particular concept was covered.

    Common Core has actually done the impossible: It is being adopted as a One True Standard to gauge a student's understanding, based on a set of concepts, rather than a district's particular placement test. Well-written tests against Common Core can also indicate whether a student has understood the concepts adequately for their grade level, based on real-world needs, rather than the opinions of a teacher who hasn't seen business needs in the past decade.

    Adding more fiat money only dilutes the value of the existing money,

    You're missing a key detail of modern economics: the debt economy. Think of money and debt as (loosely) matter and anti-matter. When they're together, they can cancel each other out, and one can be produced by producing an equal (except for an mentioned below) amount of the other. The federal reserve bank is able to do this, and that's where the "out of thin air" magic happens.

    By producing money, which is then loaned to banks, the banks have enough money on hand to serve their customers' needs, including making more loans. That allows corporate customers to have enough money available to continue to do business, including paying out paychecks. That lets individuals continue to have money to spend, which goes back to keeping business moving. Ultimately, that's the goal of any economy: to keep goods and services moving from the people who produce them to the people who need them.

    The other side of the economy is the debt. When the banks receive the loan from the Fed, they also get an equal amount of debt they are obligated to pay back. When borrowers get their loans, they also get debt. Debt, of course, doesn't get sent out with paychecks, so the borrowers have to pay the debt out of their profits, which limits how quickly they are willing to spend the money they have secured. That prevents runaway spending, and keeps the value of the money stable.

    The Fed, then, can control inflation by controlling the interest rate, which affects the balance of money and debt. If they lower the interest rate, businesses (which make up the vast majority of economic transactions) are able to put more money into circulation, at the risk of increasing inflation. If they raise the interest rate, the debt increases, which will help prevent inflation, but has the risk of stopping the all-important circulation of goods and services.
