#2 and similar situations will be _well_ mitigated by the plethora of data collected before and during the accident. It's no longer a question of who-said-what, where the impact was on the car, and estimates based on skid marks. Between recorded lidar imaging, video imaging, and all the telemetrics needed to automatically drive the car: Driverless car impacting other driverless car; probably a software error. Driverless car impacting / being impacted by a piloted car, and it will be fairly easy to see which driver made the error which led to the crash. Car / AI manufacturers will have more of a liability for making certain their vehicle is safe, no doubt. This is a win/win situation for the automobile owner. Safety is now an economic force not dictated by regulation.
