So, it should be a good representation of the lines of sight of the B-pillar camera (obviously the extents of the field of view will be different since the one on the top is pretty wide angle)
100% agreed.
I have a very comprehensive on-the-ground video to reference, taken with a high quality camera, from Chuck. Also drone video from Chuck, which helps us with distances! As we well know, cameras (especially wide angle ones) have distortion, which can make judging distances difficult. However, please see the analysis below.
You should go back to this intersection and look again. Detection RANGE may be an issue (I have no idea), given vehicle speeds, but obscuration is not an issue, even with the current limited sensor placements.
There is zero resistance here, if that were actually the issue. But I don't think it's a good idea to change something if it's not the problem. Gotta root cause things!
I'm absolutely willing to say that improved cameras and more sensors may well be necessary to achieve better than human performance, in general (with the current status of compute and AI). But I have no idea! However, that's completely different than saying that that is the problem
here. Again, I am simply trying to state that the root cause of the issues
here is
not the camera placement or the visibility.
So, can we please stop saying that visibility is an issue for
this corner? It's really not, as long as the car's stopping pose is correct! And there is TONS of margin. There is 20' or more from the main stop line to the edge of the first lane. The Model Y is 15.5' long. Visibility begins to be sufficient about 5' forward of the thick main stop line. The position of the B-pillar camera (I'd estimate 8' from the front of the vehicle) is therefore definitely far enough forward to have an unobstructed view.
In the screen capture below, you can see the distances marked off relative to the known Model Y size. And you can see that in this pose, the Model Y will have great visibility (in the overhead view, the b-pillar camera is at least 2-3 feet forward of the first crosswalk line).
So for
this specific turn, as I calculate it, there is approximately a 7' window of positioning for the car. This seems ample! 5' if you want to be 2' back from the edge of the traffic lane.
This is why Tesla is working on improvements in stopping pose (and presumably consistency)...

Adding one more picture showing the view corresponding to the overhead measurements above (this is after Chuck disengaged). Visibility is excellent as others have pointed out! This is at 10:22. It takes 8 seconds for the vehicle with headlights on in the closest lane to reach Chuck's position, at 10:30, so that is about 200 meters:
