Should a Driverless Car Decide Who Lives or Dies?

The gearheads in Detroit, Tokyo and Stuttgart have mostly figured out how to build driverless vehicles. Even the Google guys seem to have solved the riddle. Now comes the hard part: deciding whether these machines should have power over who lives or dies in an accident.

The industry is promising a glittering future of autonomous vehicles moving in harmony like schools of fish. That can’t happen, however, until carmakers answer the kinds of thorny philosophical questions explored in science fiction since Isaac Asimov wrote his robot series last century.

For example, should an autonomous vehicle sacrifice its occupant by swerving off a cliff to avoid killing a school bus full of children?

Auto executives, finding themselves in unfamiliar territory, have enlisted ethicists and philosophers to help them navigate the shades of gray. Ford, General Motors, Audi, Renault and Toyota are all beating a path to Stanford University’s Center for Automotive Research, which is programming cars to make ethical decisions and see what happens.

“This issue is definitely in the crosshairs,” says Chris Gerdes, who runs the lab and recently met with the chief executives of Ford and GM to discuss the topic. “They’re very aware of the issues and the challenges because their programmers are actively trying to make these decisions today.”

Automakers and Google are pouring billions into developing driverless cars. Ford said it was moving development of self-driving cars from the research lab to its advanced engineering operations. Google plans to put a “few” of its self-driving cars on California roads this summer, graduating from the test track.

Cars can already stop and steer without help from a human driver. Within a decade, fully automated autos could be navigating public roads, according to Boston Consulting Group. Cars will be among the first autonomous machines testing the limits of reason and reaction in real time.

“This is going to set the tone for all social robots,” says philosopher Patrick Lin, who runs the Ethics and Emerging Sciences Group at California Polytechnic University and counsels automakers. “These are the first truly social robots to move around in society.”

“I wouldn’t want my robot car to trade my life just to save one or two others,” Lin says. “But it doesn’t seem to follow that it should hold our life uber alles, no matter how many victims you’re talking about. That seems plain wrong.”

That’s why we shouldn’t leave those decisions up to robots, says Wendell Wallach, author of “A Dangerous Master: How to Keep Technology from Slipping Beyond Our Control.”

“The way forward is to create an absolute principle that machines do not make life and death decisions,” says Wallach, a scholar at the Interdisciplinary Center for Bioethics at Yale University. “There has to be a human in the loop. You end up with a pretty lawless society if people think they won’t be held responsible for the actions they take.”

As Wallach, Lin and other ethicists wrestle with the philosophical complexities, Gerdes is conducting real-world experiments. This summer on a racetrack in northern California, he’ll test automated vehicles programmed to follow ethical rules to make split-second decisions, such as when it’s appropriate to disobey traffic laws and cross a double yellow line to make room for bicyclists or cars that are double-parked.

“There’s no sensor that’s yet been designed,” Gerdes says, “that’s as good as the human eye and the human brain.”
