F 1 What does a safety car do in racing?

As the name implies, a safety car is a car prepared for the safety of the game. Its purpose is to lead the team to circle at a speed of less than 60 kilometers per hour in the event of an accident in the competition. For example, when the car in front has an accident crossing the track or debris is left on the track, the car behind doesn't know that there is an accident car in front, which may lead to a series of crashes. After the accident, the safety car ran in front of the car and walked slowly so that the stadium staff could clean up the accident car. Safety car drivers are all retired drivers.

1976, during a match in Italy, a racing car caught fire and stopped at the track. Two track staff took fire extinguishers to save the racers. They crossed the track before the safety car was dispatched. The first one passed the track safely, and the second one was cut off by a car with a speed of 256 kilometers per hour and scattered all over the track. Then the fire extinguisher in his hand hit the driver who hit him. The driver fainted on the spot and the car lost control. The accident eventually killed two racers and a rail worker, and 12 spectators were injured. This also highlights the importance of safety cars in the competition.
