What sort of fine tuning data was needed to allow the model to self-drive? One hour of video of someone driving, or extra labeling?

i actually drove the car (with arrow keys) around south park for around ~45 minutes as finetuning data, no extra labelling other than that. think the car line graph is super cool because you actually see the videegame prior working

relevant note is that we finetuned by having the human also use arrow keys which keeps it in-distribution but also slower to collect
