AUTOMOTIVE

Pumping the Brakes

Fast-tracking autonomous vehicle development exposes safety risks, technology gaps

Four months after Tesla’s autopilot feature caused the first known fatal car crash involving a self-driving vehicle last May, Amnon Shashua, CEO of former Tesla supplier Mobileye, said the automaker was "pushing the envelope in terms of safety" and that autopilot technology was "not designed to cover all possible crash situations in a safe manner."1

Rolling out technology that puts people’s lives in the hands of computers has consumer watchdogs asking whether the technology’s current state is safe enough for public use. If it’s not safe, how safe is safe enough? These concerns haven’t slowed the pace of development, however, as automakers and regulators continue to pour resources into making self-driving vehicles a reality sooner than later.

Safety in transition

Following the Tesla crash, Kirk Steudle, director of the Michigan Department of Transportation, said that driver error is the cause of most traffic deaths and suggested people put the crash into context: "That same day there were 95 other fatalities … and every day since then there have been 95 more fatalities."2

This take on the situation may help explain the government-industry partnerships and plans that are making self-driving vehicles a seemingly serious priority. For example:

  • The United States this year committed $4 billion in its federal budget to self-driving vehicle research and promised to achieve zero road deaths by 2030, a commitment heavily reliant on self-driving vehicles. It also issued the first guidelines for safety expectations and rules for autonomous driving technology, such as how a vehicle should react if there’s a system failure, how it will communicate with other vehicles and vehicle cybersecurity.
  • California Department of Motor Vehicles last month revised its guidelines to be less restrictive on organizations by giving them more leeway for testing self-driving vehicles on public roads, allowing for more innovation and curbing misleading advertising for semi-autonomous features such as Tesla’s autopilot. The state prohibited use of terms "autonomous" or "self-driving" for such technology.3-5
  • Two automakers this year announced bold plans for their self-driving efforts: Ford and Volvo said they will release fully autonomous vehicles by 2021.
  • Uber gave its passengers a taste of what might come after launching self-driving taxis in September in Pittsburgh.6, 7

"We are in this weird transition," said Karl Brauer, senior editor at Kelley Blue Book, "It’s a tough balance for the regulators. You want to get this technology out, but you don’t want to move too quickly."8

Limitation concerns

Amid this flurry of activity aimed at fast-tracking autonomous vehicle deployment, consumer advocates have begun to speak up.

Joan Claybrook, a consumer-protection advocate and former head of the U.S. National Highway Traffic Safety Administration (NHTSA), said she was skeptical of Uber’s self-driving taxi release in Pittsburgh because the state of Pennsylvania doesn’t have rules about what happens in case of a crash, and Uber isn’t required to share vehicles’ data with regulators.9

"They are essentially making the commuters the guinea pigs," Claybrook said. "Of course there are going to be crashes. You can do the exact same tests without having average citizens in your car."10

Safety experts, too, said current self-driving technology has dangerous limitations, such as vision sensors being hampered by rain, snow and puddles, and misidentifying bridges for actual obstacles.11

Other popular safety features installed in today’s vehicles, such as emergency braking, lane-departure warnings and adaptive cruise control that rely on Lidar (light detection ranging) to map out a car’s surroundings, are having issues, too.

Glen De Vos, Delphi Automotive vice president of engineering, said these systems’ sensory gaps must be improved because they will be vital components in tomorrow’s autonomous vehicles, and drivers will expect them to always work reliably.12

De Vos and other engineers are still working out these systems’ kinks, such as how sensors blend their data for more accurate mapping; how vehicle-to-vehicle or vehicle-to-infrastructure communication will be made available to update road conditions; and systems’ abilities to recognize animals, bicyclists and pedestrians.13

Human factors

Uber’s self-driving taxis have two drivers on hand to take over in case of an emergency, but relying on humans to take control in case of a system failure could lead to deaths similar to that in the Tesla crash.

"If you have to rely on the human to see something and take action in anything less than several seconds, you are going to have an accident like we saw," said Missy Cummings, director of Duke University’s Humans and Autonomy Laboratory.14

People typically struggle to maintain focus on boring tasks such monitoring systems that rarely fail, according to decades of research involving aviation and rail transportation. People’s minds wander until they find something more interesting to focus on. So the more reliable the system, the more potential for people’s attention to wane.15

Ford recently announced it will skip a step in autonomous vehicle development by not designing vehicles that require a driver to pay attention and take over if a vehicle misses an obstacle. "If you really want to drive autonomously, you need to have the capability in your vehicle to be able to make really hard decisions," said Ken Washington, Ford’s vice president of research and advanced engineering.16

After Tesla’s fatal crash, the automaker said it had repeatedly reminded customers that they must keep their hands on the wheel and be attentive while using autopilot, but that didn’t stop many Tesla drivers, who ignored the advice and posted videos of themselves reading newspapers, drinking coffee and even riding on the roof while autopilot was engaged.17

In September, Tesla rolled out two over-the-air updates (downloaded by Tesla vehicles in the way smartphones update their apps) to improve autopilot’s safety. Radar was given a more active role because the old system could cause a Tesla to scrape against a vehicle partially in its lane or hit an obstacle that a vehicle ahead of it avoided.18 The update also caused autopilot to disengage if a driver removes his or her hands from the wheel.19

Making connections

With about 40,000 auto-related deaths in the United States last year—the largest year-over-year percentage increase in 50 years despite vehicles having more safety equipment than ever before—the motivation to push humans out of drivers’ seats is clear.20

Advocates of autonomous vehicles also point out less talked about benefits, such as having an internet connection similar to Tesla’s that can receive over-the-air updates.

"An over-the-air update could literally address a defect and (handle) 100% (of) recalls overnight," said Mark Rosekind, the administrator of the NHTSA. "That’s the kind of innovation you’re looking at."21

Consider a more practical issue that connected vehicles could help alleviate: traffic jams. In San Francisco, for example, road congestion could be reduced by 20 to 30% if drivers were connected with available parking spots through dashboard screens instead of searching the streets. Traffic data company Inrix already provides such a service for some of today’s luxury cars.22

Miles away

Self-driving technology has a long road ahead before fully autonomous vehicles can be possible. Several artificial intelligence (AI) systems are being trained to recognize the nearly infinite number of encounters their environments could throw at them. According to Andrew Moore, dean of Carnegie Mellon University’s School of Computer Science, AI systems that can interpret conditions that require near-human reasoning abilities pose a serious challenge to designers.23  

"It’s that last 10%, and then that last 1% of circumstances that gets very, very difficult to solve," Moore said. "Autonomous in-town driving, I’m still putting it at 2028."24

Nidhi Kalra, senior information scientist at RAND Corp. and co-director of its Center for Decision Making Under Uncertainty, said AI struggles with tasks a human considers common sense—such as how to react if a child runs in front of the car or a bicyclist is encountered on a narrow street. For instance, would the car decide to briefly go into oncoming traffic to avoid the person?25

"Makers of this technology need to achieve a level of performance we wouldn’t expect from a human driver," Kalra said. "What kind of risk we are willing to accept to gain some of the benefits of the technology? Being better than the average human is not good enough, even though that might save lives."26

HEALTHCARE

Poll: Better Workflows Essential to Implement Healthcare Technology

Designing workflows that improve efficiency and technology adoption should be a top priority to help healthcare organizations strengthen the quality of their technology implementation, according to a recent ASQ poll of U.S. healthcare quality improvement professionals.

According to results of the online poll of more than 170 ASQ members in the healthcare quality profession, 78% said improving workflow efficiency is the No. 1 way organizations can improve the quality of healthcare technology implementation. Priority should be given to nurturing strong organizational leaders who champion healthcare technology initiatives, 71% of respondents said.

According to respondents, these technologies can have the most impact on patient experience and care coordination:

  • Incorporation of wearable sensors, remote patient monitoring and other caregiver collaboration tools (71% of respondents).
  • Smartphones, tablets and applications providing a wealth of information for physicians and other clinicians (69%).
  • Online communications along every step of the patient process—for example, website, registration and payment (69%).

Survey respondents said many of the factors that would improve healthcare technology have hurdles that make implementation prohibitive for healthcare organizations, including:

  • Resistance to change from physicians and staff due to perceived impact on time and workflow and unwillingness to learn new skills (70% of respondents).
  • High costs of implementing IT infrastructure and services, and unproven return on investment (64%).
  • Problems with complex new devices, poor interface between multiple technologies and the haphazard introduction of new devices that could cause patient errors (61%).

Date in Quality History

QP looks back on a person or event that made a difference in the history of quality.

Nov. 19, 1925

Henri Fayol, a French mining engineer and management theorist, died on this date. Many call Fayol one of the most influential contributors to modern concepts of management and a key figure in the classic school of management theory.

Fayol developed a general theory of business administration, also known as Fayolism, which included 14 principles of management: division of work, authority, discipline, unity of command, unity of direction, subordination of individual interest, renumeration, centralization, line of authority, order, equity, stability of tenure of personnel, initiative and esprit de corps (employee morale).
