Suicidal races at 300 kilometers per hour recorded on the M-50 in Madrid: "They put their lives and those of other drivers at risk". The Civil Guard is investigating a series of videos spread on social networks where drivers boast of reaching 300 km per hour.

They are clandestine races that are held at dawn and on weekends where the challenge is to reach the maximum possible speed after having reprogrammed the car's electronic system. "This is the milk, for my eggs that I pass to you," is heard in several of the images. It is suspected that they have some mechanical workshops where cars are manipulated.
