Recently, one of Uber's autonomous automobiles was involved in an accident where a pedestrian was killed. What lesson should we learn from this incident? The potential for autonomous vehicles to produce tremendous saving of lives and injuries while increasing our quality of life provides strong support for the eventual introduction of fully automated vehicles. Nonetheless, just as new medicines and medical devices enhance lives, but their introduction is done cautiously, with carefully controlled tests certified by a trusted, neutral agency or company (e.g., FDA for medicine, FAA for aviation, UL for home appliances), we must do the same with our autonomous vehicles.
