The guy over simplify, a machine is far from being as good as a human to drive ON SOME areas, for example... you can catch a strange behavior of a pedestrian and slow down before he suicidal under your wheels. Machine can't do that and will not be able to do that before decades. NOW... Humans got big flaws on driving (exemple reaction time) and SOME of those flaws can be solved, improved by a machine. What i'm saying is that... A machine can overall be better then the average driver... BUT it will still generate stupid accidents that the audience will not accept, and for a good reason. Cause... If a human bump into a pedestrian we can say it's just that one human that is responsible for it... If there are millions of cars and one bump into a pedestrian... Then... In a way they are all faulty.. And saying afterward.. "we patched it" will certainly not be acceptable kn the long run... Cause there are millions of posibilities where an accident can occurs.
