How do the cars do when breaking a rule is necessary? For instance, a car is broken down in the one forward lane of a two-lane road, requiring the waymo to cross the double-yellow line to get around it. Or, a signal is red for so long that obviously its car detector isn’t working.

It handles these circumstances. Definitely seen it cross to the other side with oncoming traffic to get around a truck blocking a lane. For the signal light, never experienced that, but I imagine after awhile it'd figure it out. Possibly with the assistance of a remote human telling it.

I was in one stopped as the first car at a red light. The next section of road was full of cars waiting on another red light.

Our light changed to green and the Waymo waited until the next red turned green and then proceeded into the intersection in anticipation of the cars ahead moving.
