Every release you can tell it's learning little more about general driving. I would call it a responsible but paranoid adult driver if you are driving in the suburbs or a city with well marked roads and controls. The problem is that it doesn't seem to even attempt certain human logic patterns, and I'm not sure a generalized approach will ever be able to infer these kind of nuances.

One begins to wonder how much is learning vs a bunch of logic manually coded for locations with the highest number of sudden manual intervention.

At AI day and in shareholder meetings they go over this regularly. Last year they described having 16 AI models for handling various situations, with the goal of eliminating all code logic and moving to a single-stack AI model capable of all situations.
