I don't think it does. Sure, a car would know that a stop sign was there the last time it drove through that intersection, but you can always order the car to go someplace new. And I don't believe the dream that "oh, automatic cars will just have 100% accurate street data for every road in the civilized world". First of all because we don't have this data, and even if we did, I can't imagine a car hauling several terabytes of data with it(and how would you even update it, given that our internet connections seem to be getting worse, not better every year, with new data and speed caps being introduced?). It has to be able to decide autonomously, and since it has to be programmed to do something, it's a really hard problem. A human can just "use best judgement", but a computer can't - it either follows the rules or it doesn't. And roads are not a computer simulation - they are dynamic, they change, they require the sort of input that computers are horrible at, visual recognition is dreadful, our best, cream of the top software can't tell a difference between a zebra and a sofa in a zebra print, and yet most people just wave their hand at the problems facing automatic cars saying "oh, we will just use a machine learning algorithm to watch how humans drive and then follow that". Sure. But it doesn't magically solve the problems of responsibility where a computer does something it shouldn't have.
