In the scenarios you described, a remote operator would "help" the car. They've specifically said remote operators can't control or joystick the car, but can "answer questions" which I take it to mean plot a different course. It can also pull over at a safe spot and not get stuck in the middle of an intersection, though nobody has run into this issue to test it from the videos I've watched.
The examples you gave sound like scenarios where remote operator would instruct "don't go there, go here" and the car does it by itself. But specifically about the traffic cop, it can actually detect hand signals from them (can't find the video though).
