But, having used and been behind other assisted driving vehicles. (Which one thing I find exhausting with auto cruise is that people pass, usually on the right, and then cut in constantly if you have the distance set safely)…
But as another commenter said about mental models of drivers. I wonder if part of it is they brake sooner, and perhaps more completely.
Example: someone turning left. Most human drivers will slow and go around if safe. Does waymo brake far away, and abruptly?
Again, I can’t comment on waymo, but I know my own vehicle too will sometimes brake late and harder if set to auto because of sensor distance. (I try to not let this happen and over ride and brake sooner of course, gradually slowing vs flying up, detecting a stop or slowdown, and then braking aggressively )
