I did repeated testing this afternoon at a highly occluded unprotected right turn that beta has never been able to do safely. I've taken this turn successfully with 10.69.1.1 and 10.69.2 a couple times, but this is the first rigorous test I've done.
The intersection is from a neighborhood street onto a six-lane divided artery road with a median blocking any left turn. On the left is a large wall resulting from widening this road some years ago, which creates a highly-occluded view of the right-most cross lane. Realistically, there should be a traffic light at this intersection, but, we must play the cards we are dealt. So...
This turn has some precise creep requirements in order for the car to see well to the left. To evaluate this, I set up a GoPro camera just above the left side B-pillar camera so that I could review approximately what the car can see. I had previously reviewed dashcam video and confirmed that the car does not position itself correctly to see cross traffic on the left repeater camera. Unfortunately, Tesla does not make the B-pillar camera video available, so I use the GoPro as a substitute.
The results were as I expected. The car is able to safely make the turn. It establishes a perfect creep wall and when it creeps up to it, the B-pillar camera can see far enough on the left to detect cars that would be a hazard. However, there are two issues with how this turn is made. First is that the car will usually not proceed unless all three lanes appear clear of traffic. This is an unreasonable gap requirement as the cross street is often quite busy. Traffic in the left-most lane is generally no danger and the Tesla could turn onto the road with that traffic present.
The second issue is the car does not commit to the turn very well. It slowly eases into the right cross lane and only after it is fully blocking the lane does it accelerate away. Once the car has occupied the lane, there is no benefit sitting there. It needs to commit.
Here's a view of the GoPro B-pillar surrogate. You can see how well the creep works. It would actually be better if the car angled itself more to the right so the cross road enters the left repeater camera's FOV. IT is possible to do that within the creep limits. But, this works as well.
