With a somewhat questionable decision, the Race Stewards have imposed a penalty on Sebastian Vettel, adding 10 seconds to his total time at the end of the Mexican Grand Prix. This means that Sebastian drops from third to fifth place. The penalty was imposed because of a move which was deemed to be “potentially dangerous” to Daniel Ricciardo. The move happened when Vettel was behind Max Verstappen, who refused to give back the position, despite the fact he had cut a corner of the track.
