The Brilliance of the Self-Driving Minivan – The Atlantic

In other words, Google’s interest in self-driving minivans has to do with building public trust, a hurdle facing the developers of driverless cars that’s arguably even greater than the remaining technological challenges.

Getting the public to trust any new technology is difficult. Leaders in the self-driving car space like to evoke the early days of the elevator as a way to explain how it takes people time to warm up to technology that will eventually become ubiquitous. “This magic thing that would whisk you up floors. You couldn’t possibly imagine relinquishing your life to this thing,” Chris Urmson, the head of Google’s self-driving cars project, told me in an interview last year.

The elevator analogy is a useful one, but it misses one of the major aspects of self-driving car technology that fuels uneasiness: How do these things make decisions?

“The vast majority of machine learning techniques we use are uninterpretable to people,” said Julie Shah, a roboticist at MIT who specializes in human-machine collaboration. “You have no insight into why or how it’s operating this way.”

The mystery of how an algorithm takes input and generates output might be acceptable to people when they’re browsing, say, personalized Netflix recommendations; but the leap of faith required to trust that a self-driving car is making the right choices is still too great for many. (In February, a survey by the polling firm Morning Consult found most people—51 percent—wouldn’t ride in a self-driving car; with 43 percent of respondents calling the technology “unsafe,” compared with 32 percent who said it was “safe.”)

“It limits how far we’ll be willing to use artificial intelligence,” Shah told me. “I see it as one of the fundamental barriers to AI supporting large portions of the work we do.”

There’s also something of a double-standard that self-driving cars will have to face. Humans expect some level of inscrutability in their interactions with other humans, for instance, but machines are afforded very little room for error.
