How do you think they lit this scene?

[Adam J McKay]

In the Fincher version of this scene(this is not the Fincher version-right?) they used an insert car to follow or chase
the motorcycle. They added some headlight fixtures with quartz globes and wide angle lenses, so the light would
fan out and hit the trees. There was a small bounced source on the camera car, about 2 stops under, and they used
narrow beam HMIs to project ahead of and above her to illuminate the forest

That would have been my guess. More powerful lights on cars and a soft source on the camera car.
