I get your point. But the approach to the situation differs I think. A human driver would creep into the intersection to get a better view and then go if clear. The Waymo proceeded with far more confidence. Just better vision. It starting tracking vehicles earlier than a human would (this is shown in a simplified way on the display inside - but I wasn't watching in this case). As it pulled into the intersection, it's front camera and/or lidar has a much better angle than a human driver so can make a go/no-go assessment earlier and without hesitation.
