Maybe not a prerequisite, but certainly necessary to prevent certain type of long-tailed events. For example, I can anticipate by the look of a neighborhood that it's more likely that there would be jaywalking and poor infrastructure, I can feel that the driver riding ahead is drunk or on drugs and keep my distance etc. It remains to be seen if a automated drivers can make-up for increased risk in such scenarios with good performance in areas they excel, such as reaction time, highly distributive attention, near perfect physical predictions and decisions made on that basis, vehicle-to-vehicle coordination and vehicle to road communication etc. What is clear though is that any practical system in the near term (non-general AI) will approach driving quite differently than a human driver. Hence the jury is still out of lidar vs camera-only approaches (Waymo vs Tesla).
