Have you noticed 10.69.25's holiday update includes a new navigation display for lane selection? It might help reveal what the navigation / maps data knows or even what's missing. Today it was quite wrong believing 3 straight lanes were triple right turns needing to be in the left two, and FSD Beta wanted to unnecessarily switch out of the left lane. The only thing I can think of causing this confusion is that there's a very small/short/narrow median the same width as double yellow lines, and somebody drew the map data as separated 1-way roads in each direction.

The bottom 2 lanes display was correct with appropriate highlighting of the left and right turns. I would think this is only displayed for an upcoming turn where map data indicates there's more than 1 lane ahead as well as the data including the turning behavior of each lane. I'll need to check again later, but earlier today I was at an intersection making a right turn and the display showed 6 straight lanes and 1 right turn lane when the left-most 3 should have been left turn.
Anybody else notice the new display and if it shows the wrong thing resulting in FSD Beta wanting to make wrong lane selection?
Similarly, if you don't see the display with 10.69.25 when turning at an intersection with multiple lanes, it could mean the map data doesn't have the lane and turn details. This probably means FSD Beta is using a Vision-only detection and heuristics to prepare for a turn at these intersections.
