> Further, we don't stop using trains, or buses when a pedestrian makes an error and gets killed because they "could have not been hit, maybe". That argument might be convincing if the car had detected the pedestrian, slammed the brakes and evaded, but still could not overcome physics in time to prevent fatal injuries. But that's not what happened. We could have built self-driving cars that mindlessly follow the road no matter what fifty years ago, but we didn't, because that kind of vehicle has no place on a public road. What changed now is not that the same danger is suddenly ok because it's 2018, what changed is that some self driving cars are supposedly much better now. Those that are not need to continue to be confined to the test track.
