In the face of heavy traffic every day, we always feel that it is disorderly. Once we see the clouds, we will find that there is still group collaboration under this "chaos": every car has its goal, and every driver strives to avoid it. Traffic accidents are individual behaviors; when driving on the road, the cars are connected end to end, the car distance is narrow but does not collide, the vehicle speeds up when the distance is increased, and the vehicle speed decreases when the distance is small. If you refuse to cooperate, the road will It will become an accumulation of waste copper and iron. Interestingly, this is not mainly the result of traffic commands by the traffic police, but the unintended result of each driver after pursuing his own goals. What does this passage mean? ['Individual behavior is the basis of group collaboration.', 'Individual behavior and group collaboration are not contradictory.', 'Group collaboration is a natural result of individuals achieving their goals.', 'Group collaboration is a very important factor in human social life.']
