This week, a self-driving vehicle struck and killed a woman in the American state of Arizona. The death is believed to be the first involving a fully autonomous car on U.S. public roads. The vehicle was operating in self-driving mode when it hit a 49-year-old woman crossing the street near the city of Phoenix. Police say Elaine Herzberg was walking with her bicycle outside the road’s crosswalk when she was struck. The Volvo SUV belonging to the ride-sharing company Uber was traveling at about 65 kilometers an hour. A driver was sitting in the vehicle’s seat even though the car was set to drive itself. After the crash, Uber announced it was halting all its road testing programs while the incident is investigated. Local and federal officials are taking part in the investigation.
