One difference between true intelligence and what we have in NNs today is, if you showed an image or two of an object to a person they could identify that object in other orientations and lighting conditions pretty well. To do the same with NNs requires thousands of examples and counter examples to train. This is why with driving how could you have enough examples of strange issues to ensure the car responds safely?
The only advantage I see today for cars driving is they don't get bored or distracted or drunk, but they certainly are not intelligent.
