Well, it's less risky to drive in a paddock if that's what you mean.

The tractor still has to dodge fences, rocks, trees, etc. No risk of lives, but it still requires a fair bit of work.

fences, rocks and trees don't move, pedestrians do, they may suddenly jump on your path, the tractor just need to calculate the route once

Fair enough, though as I understand the tractors try to avoid rocks, and so they may have to change their route whilst on the job.
