Tesla announced the latest software update for its self-driving cars on Sunday, revealing that the vehicles will be relying more heavily on radar to make decisions. The announcement comes several months after it was revealed that a driver using autopilot was killed when his Tesla failed to notice a truck stretching across the road in front of him. All Tesla cars manufactured after October had already been using radar for autonomous driving, but relied more heavily on the car's optical camera.
The update to Version 8. Tesla's announcement came with some interesting insight into how its vehicles will avoid accidents in the future--and apparently make the driving experience a smoother one. It's all about machine learning : Teslas have the advantage of collecting data from the entire fleet and how drivers behave at certain GPS locations, then using that information to make future decisions.
As Recode points out, Tesla's blog post on the update explains that radar can be tricked into thinking there's an obstacle up ahead, when in reality it's a low bridge with a dip under it or an overhead sign at a point where the road inclines. To solve that, Tesla cars that are not on autopilot note whether or not drivers brake at that specific location, then upload that information to the company's database. If several cars drive past something without braking, it's added to what Tesla calls a "geocoded whitelist" of objects that don't require braking.
On the other hand, if the Teslas notice some people are slowing at a certain location, the fleet will add mild braking, even if its optical camera doesn't detect any object. If Tesla's fleet becomes In this way, Tesla creates a map of the world, noting obstructions that it should always break for, plus areas where its radar is and isn't likely to produce false positives. Tesla seems confident in its fleet's learning ability: "The net effect of this, combined with the fact that radar sees through most visual obscuration," the company wrote in the post, "is that the car should almost always hit the brakes correctly even if a UFO were to land on the freeway in zero visibility conditions.
A big advantage of using radar: It can see past vehicles in its path by sending radar pulsations around them, then detecting the echo that returns. So even if a car in front of a Tesla doesn't notice an obstruction or brakes late or drives right into it, the trailing Tesla should be able to brake ahead of time and avoid both.
Like any form of artificial intelligence, Tesla's fleet will only grow smarter as more people use it. These are relatively early days in Tesla autonomous driving--there are only aboutTeslas currently on the road using this radar technology.
The cars' AI it will be at its safest when there are more vehicles to help establish Tesla's maps and its fleet has learned with almost near certainty what does and doesn't constitute an obstruction in the road. That said, a big part of what makes Tesla a hit with consumers, and what perhaps gives it the best chance to remain relevant over time, is that it's a software company at its core. Having a product that can be updated continually is a compelling sales pitch.
Very few vehicles grow smarter as they get older the way Teslas do.

People are now paying for robot rides. And it's just a start. Waymo will expand the service's capability and availability over time.
Meanwhile, its onetime monopoly has evaporated. Smaller startups like May Mobility and Drive. Ride-hailing companies like Lyft and Uber are hustling to dismiss the profit-gobbling human drivers who now shuttle their users about. Countless hungry startups have materialized to fill niches in a burgeoning ecosystem, focusing on laser sensors, compressing mapping data, setting up service centers, and more. This 21st-century gold rush is motivated by the intertwined forces of opportunity and survival instinct.
Simultaneously, it could devastate the auto industry and its associated gas stations, drive-thrus, taxi drivers, and truckers. Some people will prosper. Most will benefit. Many will be left behind. The moniker made sense: Here were vehicles that did what carriages did, minus the hooves. Over a century, it reshaped how humanity moves and thus how and where and with whom humanity lives. It had laid a foundation for this technology, but stalled when it came to making a vehicle that could drive at practical speeds, through all the hazards of the real world.
Great for spotting things like lane lines on the highway, speed signs, and traffic lights. Some developers think that, with better machine vision, they can use cameras to identify everything they see and navigate accordingly. Good thing dozens of startups and tech giants are pouring millions of dollars into fixing all that. At its simplest, this artificial intelligence tool trains computers to do things like detect lane lines and identify cyclists by showing them millions of examples of the subject at hand.
Before a robocar takes to the streets, its parent company will use cameras and lidars to map its territory in extreme detail. A regular presence in cars since the late s, radars bounce radio waves around to see their surrounding and are especially good at spotting big metallic objects—other vehicles.
The Grand Challenge was something of a mess. Each team grabbed some combination of the sensors and computers available at the time, wrote their own code, and welded their own hardware, looking for the right recipe that would take their vehicle across miles of sand and dirt of the Mojave. The most successful vehicle went just seven miles. Most crashed, flipped, or rolled over within sight of the starting gate.
But the race created a community of people—geeks, dreamers, and lots of students not yet jaded by commercial enterprise—who believed the robot drivers people had been craving for nearly forever were possible, and who were suddenly driven to make them real.
They came back for a follow-up race in and proved that making a car drive itself was indeed possible: Five vehicles finished the course. By the Urban Challenge, the vehicles were not just avoiding obstacles and sticking to trails but following traffic laws, merging, parking, even making safe, legal U-turns.
When Google launched its self-driving car project init started by hiring a team of Darpa Challenge veterans. A few years later, Elon Musk announced Tesla would build a self-driving system into its cars. And the proliferation of ride-hailing services like Uber and Lyft weakened the link between being in a car and owning that car, helping set the stage for a day when actually driving that car falls away too.Since the s, science fiction writers dreamed of a future with self-driving cars, and building them has been a challenge for the AI community since the s.
By the s, the dream of autonomous vehicles became a reality in the sea and sky, and even on Mars, but self-driving cars existed only as research prototypes in labs. Although the technological components required to make such autonomous driving possible were available in —and indeed some autonomous car prototypes existed    —few predicted that mainstream companies would be developing and deploying autonomous cars by But in eight short years, fromspeedy and surprising progress occurred in both academia and industry.
Tesla has widely released self-driving capability to existing cars with a software update. It is not yet clear whether this semi-autonomous approach is sustainable, since as people become more confident in the cars' capabilities, they are likely to pay less attention to the road, and become less reliable when they are most needed.
The first traffic fatality involving an autonomous car, which occurred in June ofbrought this question into sharper focus. In the near future, sensing algorithms will achieve super-human performance for capabilities required for driving. Automated perception, including vision, is already near or at human-level performance for well-defined tasks such as recognition and tracking. Advances in perception will be followed by algorithmic improvements in higher level reasoning capabilities such as planning.
A recent report predicts self-driving cars to be widely adopted by We will see self-driving and remotely controlled delivery vehicles, flying vehicles, and trucks. Peer-to-peer transportation services e.
Beyond self-driving cars, advances in robotics will facilitate the creation and adoption of other types of autonomous vehicles, including robots and drones. It is not yet clear how much better self-driving cars need to become to encourage broad acceptance. The collaboration required in semi-self-driving cars and its implications for the cognitive load of human drivers is not well understood.
But if future self-driving cars are adopted with the predicted speed, and they exceed human-level performance in driving, other significant societal changes will follow. On average, a commuter in US spends twenty-five minutes driving each way. And the increased comfort and decreased cognitive load with self-driving cars and shared transportation may affect where people choose to live.
The reduced need for parking may affect the way cities and public spaces are designed. Self-driving cars may also serve to increase the freedom and mobility of different subgroups of the population, including youth, elderly and disabled. Self-driving cars and peer-to-peer transportation services may eliminate the need to own a vehicle.
The effect on total car use is hard to predict. Alternatively, shared autonomous vehicles—people using cars as a service rather than owning their own—may reduce total miles, especially if combined with well-constructed incentives, such as tolls or discounts, to spread out travel demand, share trips, and reduce congestion.
The availability of shared transportation may displace the need for public transportation—or public transportation may change form towards personal rapid transit, already available in four cities,  which uses small capacity vehicles to transport people on demand and point-to-point between many stations. As autonomous vehicles become more widespread, questions will arise over their security, including how to ensure that technologies are safe and properly tested under different road conditions prior to their release.
Autonomous vehicles and the connected transportation infrastructure will create a new venue for hackers to exploit vulnerabilities to attack. There are also ethical questions involved in programming cars to act in situations in which human injury or death is inevitable, especially when there are split-second choices to be made regarding whom to put at risk. The legal systems in most states in the US do not have rules covering self-driving cars. Even these laws do not address issues about responsibility and assignment of blame for an accident for self-driving and semi-self-driving cars.

Then again, how did you not expect them to be? Google is everywhere. Leave your conspiracy theories in the comments section. Cars can stay in lane, keep a distance from other vehicles on the road and make sure drivers stay aware of surroundings. In such a case, the car can stop itself on the side of the road and contact medical and law enforcement personnel. Depending solely on the choice of the manufacturer, Artificial Intelligence in Self-Driving Cars cars can use a variety of sensors such as lasers, radars, cameras, and even sonar.
What these sensors do is create a map of their surroundings and send the information to artificial intelligence software that has been coded into the computers present in the vehicles.
Using various algorithms for avoiding obstacles, object differentiation and many more, the vehicle is able to perform various tasks such as lane assistance, accelerating and decelerating, distance maintenance as well as stopping.
Source: ucsusa. The simplest answer is YES. Fully autonomous mass-produced cars are mostly not legal for use on public roadways. For example, the ParkShuttle credited as the first truly autonomous car transported people within confined areas on specially designed roads because it required special magnets to be embedded into the road for it to function.
What magnets? There are certain places around the world where fully autonomous vehicles are allowed to roam but much like the ParkShuttle, they are limited to these small pockets of the world.
Semi-autonomous cars, on the other hand, are completely legal. The technology has been active on public roads and is not as dangerous as cars that move around by themselves. Like every other piece of new technology with a large impact, fully autonomous vehicles will need some time to be accepted by lawmakers and governing bodies around the world.

With any technology, be it an autonomous car or your washing machine, there is always a possibility of a machine faulting. Most semi-autonomous cars provide layer upon layer of safety technology to keep drivers and pedestrians alike from harm. On the other hand, fully autonomous vehicles are a little more tricky to deal with.

A fully self-driving car would be able to drive you from Los Angeles to New York City all on its own while you sit back, relax, and enjoy the smooth ride. Self-driving cars have been receiving tremendous attention as of late, in large part due to the technological boom of Artificial Intelligence AI.
Put simply, AI has given us the ability to automate a lot of manual work that would previously have taken some form of human knowledge or skill. In the case of self-driving cars, AI can help with being the brains of the cars doing things like automatically detecting people and other cars around the vehicle, staying in the lane, switching lanes, and following the GPS to get to the final destination. So how does all of this work?
How are scientists, engineers, and software developers able to program computers to make them drive cars? When talking about self-driving cars, most technical experts will refer to levels of autonomy. The level of autonomy of a self-driving car refers to how much of the driving is done by a computer versus a human.
The higher the level, the more of the driving that is done by a computer. Check out the graphic down below for an illustration. Most self-driving cars that we hear about in the news today such as those made by Tesla and Waymo are at level 2. The self-driving cars of today use a combination of various cutting-edge hardware and software technologies to perform their driving. A typical self-driving system will go through 3 stages to perform its driving.
In the sensing stage, cameras and various sensors are used to see any objects that are around the car such as other cars, humans, bicycles, and animals. In the understanding stage, various AI algorithms, mainly Computer Vision, are used to process the information from the sensors.
For example, we might have one computer vision system that processes the video coming from the cameras around the car, to detect all of the other cars on the road around it. In reality, these systems are designed to map out the entire environment around the car. All of this information will be fed into the control stage of the self-driving.
In the control stage, the self-driving system will process all of the information that the computer vision system was able to extract. Based on that information it will control the car. A self-driving car also needs eyes to see. The eyes of the self-driving car are its various sensors. Most self-driving cars are using one or some combination of 3 different sensors: cameras, radar, and LiDAR.
Cameras are the most similar to our own eyesight. Self-driving cars will have cameras placed on every side: front, back, left and right and more to be able to see everything around them, a full degrees. Sometimes, a mix of different types of cameras will be used — some wide-angle to have a wider field of view, and some narrow but high resolution to see further. A car is seeing exactly what a human driver would see — and more since its internal computer can look through all of the cameras at once.
Cameras are also very inexpensive. Radar has been traditionally used to detecting moving objects like aircraft and weather formations.
It works by transmitting radio waves in bursts or pulses. Once those waves hit an object, they bounce right back to the sensor, giving data on the speed and location of the object. In self-driving cars, radar is used to detect the speed and distance of various objects around the car. And just like the cameras, the radar will be used in degrees around the car. Radar also supplement cameras in conditions where there is low light, such as night-time driving.
The drawback of radar is that the technology is currently limited in its accuracy. Current radar sensors offer a very limited resolution. It works by sending out beams of light and then calculating how long it takes for the light to hit an object and reflect back to the LiDAR scanner.
The distance to the object can then be calculated using the speed of light — these are known as Time of Flight measurements.If this is your first time registering, please check your inbox for more information about the benefits of your Forbes account and what you can do next!
Social distancing involves probabilities, and handy lessons from AI self-driving cars. When you get behind the wheel of your car and go for a leisurely drive, you become an estimator of probabilities whether you realize it or not. Assuming that you are a conscientious driver I hope so!
For example, you might look to see if the dog is heading away from the street, toward the street, or paralleling the street, plus carefully observe the pace of the pooch.
Meanwhile, you might be considering the speed of your car as it is rolling along, and be judging the timing of when the car could reach the point that the dog might startlingly end-up in your path, assuming that the dog decides to dart out into the street.
On the other hand, you know that the dog has lived on the block for many years, and never had any incidents with cars, thus, in your mind, you would rate the probability pretty low that the dog will opt to do so now. Overall, there are seemingly numerous and complex innate probability calculations going on in your noggin about this evolving situation. Furthermore, not only are you estimating those distinct or individual probabilities, you are combining them together to guide your actions as the driver of the car trying to blend or unite together I, E, T, and H, overallincluding coping with those events that are independent of each other and those that are dependent upon each other.
The overarching point is that you had to make judgments or assessments that involved probabilities.
Top 23 Startups developing AI for Self-driving Cars
Some of you might right away be protesting that you drive a car all the time and never need to mathematically make such arcane calculations.
In other words, you insist that your mind is not somehow identifying a numeric value for the likelihood of an event, nor that you are using some complex formula to combine together the probabilities of numerous potential events as though trying to arrive at an overall probabilistic score.
Unlike the probabilities that you might have learned in school, admittedly your mind might not be converting the things you see and do into a numerical description that consists of a probability value between 0 and 1, whereby 0 means the chances are nil of the event occurring and the vaunted value of 1 means it is an absolute certainty.
For all we know, your mind uses some other approach to deal with probabilities. Our minds are one of the greatest hidden mysteries, locked away in our brain, and within seemingly easy reach, yet remains incredibly inscrutabledespite modern attempts by cognitive scientists, psychology researchers, neuroscientists, and others.
In describing the car driving example about the dog, you might have noticed that I purposely indicated that you were taking a leisurely drive. Imagine how your mind must be racing with probabilities when you are driving under pressure, such as driving on the freeway, in the rain, on the way to work, and you are late and trying to make up for the lost time by driving aggressively.
It would appear that drivers might adjust their belief about probabilities, based on the context of the driving situation. Since you are late to work, you might mentally justify going past the speed limit and reduce your personal assessment of the probability of getting into a wreck, simply to rationalize your bad driving behavior. In the United States alone, Americans drive about 3. This almost seems like a miracle, when you consider that having about million licensed drivers taking to the roads for trillions of miles is bound to be a scary thing.
True self-driving cars are ones that can drive without the need for a human driver. The AI system is able to drive the car, and never need to ask assistance from a human driver, and nor require that a human driver is at the wheel and ready to take over the vehicle. Developing an AI system that can be fully autonomous when driving a car is a lot harder than it might seem.
If you remain incident-free, apparently you are doing well at your probability estimations. When you get into a car crash, we question your probability thinking and you can potentially go to jail or suffer financial penalties for your driving results. Another facet about self-driving cars involves establishing virtual boundary boxes around detected objects, and estimating the chances or probabilities that those objects might physically encounter the self-driving car see the link here for my analysis of such aspects.
If the data collected was based on say aggressive New York City drivers, presumably the AI system would then have a tendency to drive in a similar vein, based upon the patterns of how those drivers tend to cut corners and take heightened risks while driving. Time will tell and so will the public and regulatorsdepending upon how the AI self-driving car adoptions proceed.
The context now involves social distancing. To avoid potentially getting infected and to try and curtail or mitigate the rapid spread of the COVID virus, social distancing has become a key tool toward fighting the pandemic. Well, once again, whether you know it or not, you are indeed making use of probabilities, albeit not necessarily in a formalized mathematical way and instead perhaps in a more instinctive and intuitive manner.
The rule-of-thumb about contact with others involves remaining at least six feet away. In any case, the basis for keeping six feet away from others is due to the attempt to avoid getting the virus on you. To try and avoid getting touched by a person that has the virus, you prudently want to stay away from the person, and though you could potentially get within a closer distance and avoid being touched per se, there are the chances too of the airborne form of physical contact, so it makes sense to remain far enough away from the person that the odds of the airborne contact are lessened too.
The probability of not physically touching a person that has the virus and that is six feet away from you is considered better than if you were within six feet, and the same is said of the airborne transmission, namely that by staying six feet away you are lowering your probability of having an airborne release of the virus be able to land on you. Taking precautions such as wearing a mask or face covering are intended to reduce the probability of C, meaning that by putting on a shield or some other precautionary artifact, you are attempting to cut down the chances of C occurring.
For people that go for a stroll or wander around where other people are, they are inextricably going to be mentally coping with probabilities as it pertains to social distancing, whether they realize they are doing so or not. Similar somewhat to the act of driving a car, the situation of the moment will cause you to adjust your perceived probabilities associated with V, R, C, and Y.
