The point is that some situations require actual reasoning to make sense of complex situations rather than trivial tactical reactions such as those. Avoiding hitting something is brain dead AI, and can be taken for granted. Interpreting gestures, seeing atpyical pedestrian traffic or street construction several blocks ahead and planning a detour is strategic and requires context identification. The context, of course, is NOT simply the "sensor data" - it is interpreted sensor data which of course, isn't automatically done, regardless of millions of miles of "deep learning". These are much higher level strategic actions,. There is no cause and effect being established, because the AI was never programmed to understand that level of driving ability.
