The GP was talking about the driver knowing if the "human has seen the machine".
For the inverse problem, we could simply start adding screens (instead of windshields?) to self-driving cars that acknowledge the pedestrians in a particular way (when there's only a few people, in the Black Mirror realm, they'd actually greet them by name using facial recognition and universal DB of everyone :).
