Perhaps I'm using the terms "learn" and "teach" too loosely, maybe "training" (as in a pet trick) is a better analogy. I'm thinking of a simpler system where the car is just recording the coordinates of a stop sign or traffic light etc at a certain GPS location along the routes that you travel most often so it knows when to expect them. If you're not on one of your normal routes it would be little better than what's out there now.
You could "train" your car by driving a route, and whenever something noteworthy comes up you drop a specific pin on the map or give a voice notation of what is there. If it's just for your personal routes it shouldn't take up much memory, it would basically be log entries at predetermined GPS coordinates with a set of options of what to do. The car would chime or tell you there's a stop or whatever coming up. Then what you do could be executed by something like a voice command, pressing an icon on the screen, manual operations (swerving, braking, slowing down, etc) or have the computer do it if it's capable enough, though some form of confirmation would be preferred.
No mistake, this is not true FSD and is not how computers are being designed to handle self driving. But it could be a stopgap approach that a driver could use as an aid for their personal commute until real FSD is truly ready, which could be quite some time away. At least it would be giving customers who shelled out good money for FSD something to tide them over.
