When someone indicates his intention to change lanes when there is no room, I slow down. I expect the same of others.
And when that doesn’t happen, you just continue on because chances are high that the next one will.
In many cases of heavy traffic, this is the only way to change lanes.
My point was that signals should be given only when you have the _opportunity_ to do such maneuver. If the lane to your right is crowded, putting your right signal on achieves nothing. In other words, your signals do not give you the right of way.
I do not think Waymo cars are unable to use their signals, but they are probably programmed not to put them on when the turn/lane change cannot be achieved anyway.
