+These are the frames the 15 participants drove (`driver1`–`driver15`). The `fast` and `slow` folders also contain `lb1_split`: routes of SimLingo's Leaderboard 1.0 split, recorded in the aggressive and conservative style and used for Stage-3 fine-tuning. They are not part of the participant data and are not counted above.
 
 Each frame has a front camera image, the ego state and controls, the navigation targets and the surrounding objects. Most routes also have per-frame commentary and VQA annotations.
