While space was being cleared for a new building, a bunch of scitales came out of the water to munch on the worker's lunches, before falling asleep in the way of everything. You, having a knack for puzzling scenarios, have been sent out to drive away the serpents with a basilisk-whistle. However, you realize that the scitales will only be driven deeper into the clearing site. Unless you make some paths
You could borrow a tractor from the worker in order to wear paths through the shrubbery. If one of the scitales awoke with a path by its head, it's certain to take the path instead. Then it should follow the path along, following any bends like in snake games and picking randomly at intersections. You aren't sure what'd happen at a dead end, so best avoid those. The workers have also mapped out where the snakes are sleeping (see below)
Scitales can generally move at around 1/4 of their length every second. They're also heavy sleepers. The only way to wake them up is all at once with your basilisk whistle
Because you've only got a rather mundane tractor to make the paths, it'll need to be in a continuous path from begining to end. But in the meantime it's rather versatile, being able to turn 90 degrees or reverse easily
There are already some preexisting paths. One leads into the water, and the other leads off into the worksite from the tractor's path. Luckily, the latter is already blocked off, so you don't need to worry about it
However, with all the panicked motion collisions could happen, either between snakes or with a snake hitting its own body. Either way, this is certain to cripple the snake, which would make it far more costly to move
Is there any way to make paths to ensure that the scitales never collide? If not, what is the lowest collision chance that can be managed?
