Another city, another intersection might have a different social norm when it comes to pedestrians crossing the four-way stop sign or the crosswalk or what have you. And so, the car also has to learn about those social norms and be able to react to it. So, like I said, we don't realize how sophisticated, how interactive and how social driving really is. And with our artificial intelligence capabilities, we have been able to incorporate a lot of that into our system behavior.
