Thermal Imaging Cameras Could Keep Self-Driving Cars Safe

After Uber's fatal self-driving crash last month in Tempe, Arizona, most observers had two basic question: Why did the car not see Elaine Herzberg crossing the street and stop before hitting her? And how can we stop this happening again, to someone else? The ride-hailing company has indefinitely suspended its testing program, and is cooperating with the National Transportation Safety Board's investigation of the crash. The NTSB hasn't revealed any findings yet, but the lidar--the laser-shooting sensor that should have spotted Herzberg, even in the dark--is an obvious focus. Maybe it had a blind spot, or lacked the resolution to identify Herzberg as a pedestrian.
