One could also argue that humans are not proof of anything, as humans frequently make mistakes and conduct dangerous maneuvers whilst driving. There are many road accidents occurring right now, today, around the world, as a result of humans being insufficient drivers.

We can say that something better than human-level driving ought to be possible without LIDAR, though; take the perception of a human (cameras) and replace the brain with a computer that can make better calculations much faster than a human can.
