The follow-the-leader-like game mimics the way the animals react in the wild (especially if someone were to walk in front of them with a bucket full of fish).
These large flocks of autumn migrants are impressive to see, whether appearing in a long line of follow-the-leader or looking like a mass of compressing and decompressing molecules.
Networking them together allows each vehicle in the line to autonomously match the acceleration, braking, and turns of the truck -- essentially a computerized game of follow-the-leader.
The next phase involves behavior, similar to follow-the-leader, during which one fish, the male, shows interest in the female and nudges her with his snout.
