our neighbours,C. as the government’s template Technically anything below level five is not an AV (Level-zero cars are what your parents drove and most cars on the road today operate at level one) So far nobody is close to deploying a level-five vehicle The cars Uber has tested on the streets of Pittsburgh Pennsylvania and Google’s experimental fleet for example operate under tightly controlled conditions But you wouldn’t know it from the torrent of press releases from companies involved in AV development "Any level of automated driving gets described by the media as driverless" says Steven Shladover a transportation engineer at the California Partners for Advanced Transportation Technology program in Richmond "Companies have gotten very good at crafting statements [about automation technologies] that will be presented in the most positive light" he says Companies have good reason for painting the rosiest scenario for their technology Shladover says "Nobody wants to appear to be lagging behind the technology of a competitor because it could hurt sales their ability to recruit top talent or even affect their stock price" he says As a result it’s easy for the public to overestimate the capabilities of existing technology In a fatal crash involving a Tesla Model S and a semitrailer in May 2016 the driver was using what Tesla describes as the car’s "autopilot" features—essentially an advanced cruise control system that can adjust the car’s speed to sync with other vehicles and keep the car within its lane That fits the definition of a level-two vehicle which means the driver is still in charge But he wasn’t able to react in time when the car failed to detect the semi Shladover believes AV companies need to be much clearer about the "operational design" of their vehicles—in other words the specific set of conditions under which the cars can function without a driver’s assistance "But most of the time they won’t say or they don’t even know themselves" he says Nothing Everything Accelerates brakes or steers Everything but with some assistance Accelerates brakes and steers Remains in control monitors and reacts to conditions Assumes full control within narrow parameters such as when driving on the freeway but not during merges or exits Must be capable of regaining control within 10–15 seconds Everything only under certain conditions (eg specific locations speed weather time of day) Nothing under certain conditions but everything at other times Everything—goes everywhere any time and under all conditions Nothing—and unable to assume control LEVEL ONE ZERO TWO THREE FOUR FIVE Your parents’ car Present fleet Now in testing Might never be deployed Where the industry wants to be Somewhere over the rainbow What the car does What the driver does Our take onthe prospects The six levels of auto autonomy Transportation experts have developed six levels that describe autonomous vehicles In general a higher number means a more independent vehicle with less for the human driver to do thanks to more sophisticated sensors cameras and algorithms We also assess the prospects for reaching each autonomy level K SUTLIFF/SCIENCE Download this graphic The six levels of autonomy were intended to tell the public where things now stand and where the technology is headed But such a classification system implies that companies will make incremental and steady progress in reaching higher levels: initially rolling out cars at level three then a few years later at level four and finally at level five But progress will likely be anything but steady Level three for example signifies that the car can drive itself under some conditions and will notify drivers when a potential problem arises in enough time say 15 seconds to allow the human to regain control But many engineers believe that such a smooth handoff is all but impossible because of myriad real-life scenarios and because humans aren’t very good at refocusing quickly once their minds are elsewhere So many companies say they plan to skip level three and go directly to level four—vehicles that operate without any human intervention Even a level-four car however will operate autonomously only under certain conditions say in good weather during the day or on a road with controlled access The technology for that capability already exists and "is trivially easy" notes Gill Pratt CEO of the Toyota Research Institute in Palo Alto California The real challenge says Pratt a former academic and government program manager in robotics and intelligent systems is developing a vehicle that can drive in "very difficult domains" such as rainy weather or crowded roads That’s level five and Shladover for one says he wouldn’t be surprised if it’s 2075 before we get there How safe is safe enough Policymakers assume that removing the human element will make driving vastly safer than it is now It’s an appealing idea: Worldwide some 125 million people die in vehicular accidents each year and many more sustain serious injuries Most experts believe AVs will greatly reduce that carnage once the technology is perfected and AVs make up the majority of vehicles on the highways But that could take years as manufacturers gain experience In the meantime policymakers must decide when it is safe enough to allow AVs on the road Congress is now considering legislation that would allow AV-makers to deploy the cars so long as they are deemed as safe as current vehicles Even that is a high bar Shladover notes He has calculated that a fatal crash now occurs once every 33 million hours of vehicle travel; an automated system will need to be extremely reliable to beat that record Related content What’s more the conventional wisdom holds that the public will be much less accepting of crashes caused by software glitches or malfunctioning hardware rather than human error "Society now tolerates a significant amount of human error on our roads" Pratt told a congressional panel earlier this year "We are after all only human" Pratt believes that even cutting the number of annual fatalities in half—saving 18000 lives in the United States for example—would not be good enough for AVs to win the public’s trust Instead he says policymakers will need to "determine what constitutes a sufficient level of safety" Some analysts believe that gradually deploying even imperfect AVs sooner rather than later could help win over the public and speed improvements "Waiting for the cars to perform flawlessly is a clear example of the perfect being the enemy of the good" says Nidhi Kalra a senior information scientist at RAND Corporation in San Francisco California She and RAND’s David Groves recently co-authored a study that urges the government to allow AVs on US roads once they can achieve a 10% reduction in fatalities from current levels Further improvements in safety the authors assert will occur more rapidly if the self-driving algorithms can learn from real-world driving rather than from computer simulations or endless trips around test tracks Gradually introducing imperfect AVs by 2020 would save twice as many lives by 2070 than if the government waited until 2040 to allow the deployment of "almost perfect" AVs they conclude (Kalra acknowledges a personal stake in AVs: Her husband Dave Ferguson is cofounder of Nuro Inc, says Kris Carter, The
