Uber's Fatal Crash and the Ethics of Testing Self-Driving Cars

Here's the strange thing about where I live: When I walk outside my office, down to busy, honk-filled four-lane road that runs by it, I'm immediately part of a wide scale science experiment. A lot of us are, here in San Francisco, in metro Phoenix, Arizona, in Pittsburgh, Pennsylvania. We didn't sign any forms or cast any votes, but here we are, in a living lab for self-driving tech. This really could be the way to stop the deaths of 40,000 people on US roads every year. The blind, the old, those who can't operate vehicles--their lives might shift wholly in a world where vehicles drive themselves.
