(Image credit: Waymo)To perceive visual surroundings, most self-driving cars have some combination of three visual systems: video cameras, radar and lidar.The AI synthesizes the data from these different systems to fully map out its surroundings and watch out for unexpected obstacles.Most driverless cars require all three: AIs require visual cameras and deep learning software to interpret objects like street lights and stop signs, and while radar catches most obstacles instantly, it’s not as good as spotting smaller obstacles as lidar. Tesla's autonomous (but not driverless) Autopilot feature (Image credit: Tesla)Some car companies tend to fog the issue by claiming cruise control tech for driving straight and avoiding obstacles is “self-driving”.Mercedes-Benz actually had to that claimed its 2017 E-Class was a “vehicle that could drive itself.”But, until AI tech is sophisticated enough to drive somewhere like a school crossing without any danger to pedestrians, most, governments won’t allow cars to drive without a human seated behind the wheel.Why should this matter to you? Because some drivers are feeling safe enough to l while their car is in motion, putting pedestrians (and themselves) at risk. It's vitally important that the autonomous vs driverless distinction become more clear to the public.So, while we’re covering autonomous cars in this piece, don’t mistake them for being driverless; most of them have at least a few years before their AIs can properly navigate the world without a human crutch.
Why do we need self-driving cars?For commuters, the answer is obvious: a chance to catch some extra shut-eye, get work done or watch Netflix instead of spending hours navigating through traffic.But why have companies invested an $80 billion and years of work into this technology?For starters, it could simply be a case of jumping on the bandwagon. Pretty much every major car company has developed or implemented some kind of autopilot technology into their cars. Not having that tech available could make a brand look out of date.But, at least some companies have bold business plans for self-driving tech beyond just fitting in with everyone else.Most car brands are very concerned with their crash safety ratings.
If driverless car tech will truly reduce the, car companies will want to push this tech forward. Waymo's self-driving minivan (Image credit: Waymo)Uber was also testing self-driving cars in Arizona until a high-profile fatal accident led to the state’s governor to Uber's testing privileges indefinitely.Uber eventually announced the closure of its self-driving car program in Arizona on May 23. Waymo self-driving minivan (Image credit: Waymo), the self-driving car division of Google's parent company, Alphabet, was formally launched in late 2016, but its self-driving tech has been in development since 2009.And that near-decade of work has paid off in arguably the most reliable driverless car we’ve seen to date.Disengagement—when a human driver has to take control of a self-driving car—is the primary metric by which automakers gauge their self-driving AI's technical skill. And Waymo’s cars: Waymo self-driving cars disengage 0.18 times every one thousand miles.For context, if a Waymo car drove across the United States and back, a human would on average have to intervene one time. Only GM’s self-driving cars come close to that level of disengagement, averaging about 1,000 fewer miles per disengagement.How has Waymo’s team achieve this level of reliability?
With a powerful system of six lidar sensors that instantly detect any potential hazards, and a deep learning system sophisticated enough to respond instantly to obstacles and weather hazards. Waymo's bold goal is to launch a “driverless ride-hailing service” in Phoenix in 2018, and eventually expand nationwide.Waymo has recently been as another area for expansion, but it may need to rely on strategic partnerships to be competitive there. Waymo's parent company Alphabet has a shaky relationship with the EU, and it lacks the brand recognition and loyalty that its European competitors have.We’ll have to wait and see if Uber’s fatal self-driving car crash in Arizona or Waymo's own collision stall any of the company's plans, however. Uber's driverless cars. Uber self-driving cars (Image credit: Uber)’s relatively late start to the self-driving game hasn’t stopped the ride-sharing company from zealously testing its AI tech on public roads, hoping to beat Waymo to the punch and start its.After purchasing, a self-driving truck company in 2015, Uber’s ATP developed its own system of cameras, radar and lidar to track obstacles, using a to power its AI tech.ATP reportedly settled on just lidar sensor, compared to Waymo’s six, to install on its 24,000 SUVs. Uber's self-drivings car have driven over one million miles on public roads, though its disengagement statistics don't stack up to Waymo’s: Uber reportedly only makes it on average before a human must intervene.Though it began with gusto, Uber's self-driving car program is currently in limbo.
After a fatal accident in Arizona in March 2018, the state's governor suspended Uber's ability to test self-driving cars in the state. Uber had already shut down tests nationwide following the accident.Then, in May, Uber announced it was shutting down its self-driving car program in Arizona completely.
It will continue tests in San Francisco, Toronto and Pittsburgh, whenever tests resume.When Uber's tests begin again, they will be in a much more limited fashion than before. As far as when they start again, Uber CEO Dara Khosrowshahi hopes to see his autonomous fleet driving in the next couple months.Uber plans to take findings from the National Transportation Safety Board's (NTSB) investigation into the fatal accident to make changes to its program. The company is also undergoing an internal safety review.The reveals that while the vehicle had an automatic emergency braking feature, this was disabled because the car was in 'computer mode.' Citing Uber, the report says the feature is disabled to prevent erratic driving behavior.Though the car detected it needed to make an emergency braking maneuver 1.3 seconds before it struck the pedestrian who later died of her injuries, the system doesn't alert the driver to take control of the vehicle.You can read more on what is in the initial NTSB report into the fatal Uber self-driving car crash. Despite the work that it's done in the self-driving car space, Uber has a big uphill battle before the public trusts its autonomous vehicles again.One way Uber is eyeing as a means for getting autonomous vehicles on the road without as great of safety concerns is.
Uber's CEO has said the companies are in talks, trying to bring some of Waymo's vehicles to Uber's driverless car fleet. However, given Uber and Waymo's past legal battle over trade secret theft, the grounds for a new partnership seem shaky. Tesla's driverless cars.
Tesla Model X (Image credit: Tesla)Tesla Model X, Model X and Model 3 cars all feature the latest version of, a sensor system of cameras, sonar and radar built for autonomous driving on highways.Tesla's AI can perform tasks like preemptively shift lanes before an exit or to avoid slower traffic, and can autosteer around more windy highways.Once you leave the freeway, your car will warn you to take control of steering.As of early 2016, Tesla owners had allegedly driven of miles in Autopilot mode. And, because Tesla scrapes data from all of its cars, it's able to gather information on apparent errors to improve Autopilot over time. That dwarfs the mere millions of public road miles that most self-driving cars have achieved. Volkswagen autonomous parking demo (Image credit: Volkswagen)Volkswagen, conversely, is braving the chaotic battleground known as for its testing.At the Hamburg Airport in Germany, VW car owners can simply drop off their cars in front of the garage and activate a smartphone app; the car then self-drives to a free parking space, using its GPS and cameras to navigate.Eventually, VW has designs to make your driverless car maintain itself, and even do your chores. The company how its cars will be able to speak with city systems to find free parking, or drive themselves to gas stations or car washes for service.Other big name car companies haven’t made their plans public for driverless cars, but do have dates in mind for when their AI tech will be ready.Hyundai hopes to have its cars fully, and also aims to have its driverless AI and traffic-tracking technology up and running in the same year. Meanwhile, Google’s rivals in the smartphone industry also have aspirations to take the search giant on in the self-driving industry.recently got permission from the California DMV to test autonomous vehicles.And even Huawei has jumped into the game, showing off a self-driving car earlier this year that ran entirely off of camera data from a smartphone.Finally, Lyft hopes to beat Uber at its own game.

Until the investigation is resolved, Uber's self-driving cars vehicles are staying off the streets (Image credit: Uber)Speaking with following Uber's fatal accident, Waymo CEO John Krafcik said that, “We're very confident that our car could have handled that situation.' Waymo will probably face significant backlash if it does face a serious accident of its own after Krafcik's bold claim.Of course, we'll have to wait until authorities conclude their investigations into the recent self-driving car accidents before we can fully assess how safe the tech is and what steps need to be taken to avoid future accidents.

What does the future hold?The history of the driverless car industry has been one of bold promises, high-profile fiascos, and general uncertainty about the future.It’s truly unclear whether governments will ever let self-driving cars operate without a human operator on a national level, though it seems we are steadily moving in that direction. This DeepXplore car crashes into things so real cars won't (Image credit: DeepXplore)However, while accidents will play a big role in the industry’s prospects, perhaps the most important issue will be whether self-driving cars prove to be safe not just from AI malfunctions, but also malicious AI attacks.A recent report called, written by academic researchers and Elon Musk’s watchdog group, detailed how hackers could infiltrate the AI of a self-driving network and cause cars to ignore safety laws.Without protections in place, driverless cars could even become weaponized for potential attacks. The researchers recommended that companies work with one another and with lawmakers to preempt potential hacking vulnerabilities.Will rivals like Waymo and Uber be willing to share such data, or will they hoard it? One can hope that companies will see the benefits of working together for the well-being of all. Will driverless cars get radical redesigns like this, or still look like cars we have today? (Image credit: Mercedes-Benz)If self-driving cars do take off, though, we can expect a future where companies rely more frequently on autonomous tech, potentially at the expense of jobs.
