He said he can’t trust the turn signals. I’m case of a human driver, there would be the behavioral cues to fall back on. But with Waymo, you can’t predict its next move at all.
Not explicitly, I think. But if it uses the turn signals without turning, I wouldn’t feel to confident that an actual turn would be preceded by a signal, much less one with enough time for me to react (“I will turn” vs “I am turning now”).
