A typical Uber driver has clearly defined responsibilities. Arrive on time, know your route, keep your car clean, and, most importantly, safely deliver your passenger to their destination. Sitting behind the wheel of a self-driving Uber—or any autonomous vehicle, for that matter—is, paradoxically, more complicated. A recent, tragic incident in which a self-driving Uber struck and killed a 49-year-old pedestrian, while a safety driver sat behind the wheel, has stirred up many conversations about blame, regulations, and the overall readiness of autonomous tech. The lingering question, however, is how we humans fit into this picture.
