This has led to dangerous outcomes. In March 2018, a self-driving Uber killed forty-nine-year-old Elaine Herzberg in Tempe, Arizona, in the first ever recorded incident of an autonomous vehicle causing a pedestrian fatality. Investigations found that the carâs deep learning model simply didnât register Herzberg as a person. Experts concluded that it was because she was pushing a bicycle loaded with shopping bags across the road outside the designated crosswalkâthe textbook definition of an edge-case scenario. Six years later, in April 2024, the National Highway Traffic Safety Administration found that Teslaâs Autopilot had been involved in more than two hundred crashes, including fourteen fatalities, in which the deep learningâbased system failed to register and react to its surroundings and the driver failed to take over in time to override it. The fallible and inscrutable statistical patterns of neural networks can also turn into a security vulnerability. In 2019, white hat hackers tricked a Tesla in self-driving mode into veering into an incoming lane of traffic.
