I don't think you can compare human cognition and driving abilities to current AI/Hardware, since the roads and all the information to drive are geared towards humans.
This being said: I do believe fully automated cars will come, but the 2 conditions I mentioned are prerequisites (in my opinion).
Visual identification algorithms are not fast enough to keep up with driving, let alone distance, direction, and speed inference. Speeding them up is a largely parallel job, but cars don't have the space/power/temperature-controlled/vibration-free environment to support the necessary hardware.
