It looks like FSD beta
intentionally ran the red light believing it had already crossed the stop line and entered the intersection, so it was continuing through as if it entered on green, which was actually for the right lane but incorrectly associated to this lane.

Notice how the predicted path blue line turns gray too early for a line that's for the school sign, so after FSD beta realizing it's going too fast to stop for this "stop line," it decides to get out of the intersection not realizing it's still before the actual stop line.
