Almost all of the remote dispatcher’s job is just identifying objects (usually road signs, traffic signals, and other vehicles) that the Waymo isn’t able to immediately identify. No remote driving, and very little manual course-plotting is being done by humans.

So basically Waymo needs humans to do what humans do daily while driving.

I do get your point, but what's the point of this tech if it cannot actually do what human drivers constantly do? you mention road work, in Canada, basically if it's not winter (hard to drive because of conditions and almost complete lack of visibility of the road and signs), it's road construction time...
