During the 1993 season, Prost and Senna continued their on-track rivalry. Prost was escorted by police to the Interlagos circuit for the 1993 Brazilian Grand Prix due to the hostility of Brazilians towards him. The two continued their on-track battles at Silverstone where Senna aggressively defended his position against Prost. At Prost's last Grand Prix, the 1993 Australian Grand Prix, he was pulled up by Senna onto the top step of the podium for an embrace.
