In constructing a self-driving robotic car, engineers face the challenge of designing a car that avoids common traffic problems like crashes and congestion  These problems can also affect fish traveling together in schools  However, the principles fish use to navigate in schools ensure that these problems are much less common within schools of fish than among cars on the road
Hence,
studying the principles fish use to navigate in schools could help engineers to design a self-driving robotic car that avoids common traffic problems
