At the 1982 San Marino Grand Prix, the two Ferraris were leading with Gilles Villeneuve ahead of Didier Pironi. The team showed the 'slow' sign to its drivers, and, as per a pre-race agreement, the driver leading at that point was expected to take the win of the Grand Prix. Villeneuve slowed and expected that Pironi would follow, but the latter did not and passed Villeneuve. Villeneuve was angered by what he saw as a betrayal by his teammate, and at one point had even refused to go onto the podium. This feud is often considered to have been a contributory factor to his fatal accident in qualifying at the next race, the 1982 Belgian Grand Prix.
