Giles Villeneuve finished 2nd at the 1982 San Marino GP at Imola, after being surpassed (betrayed according to Giles) by Didier Pironi in one of the most controversial team-mates dispute of F1.

After the Renaults of René Arnoux and Alain Prost retired, Villeneuve led from Pironi with a big margin of the Tyrell of Michele Alboreto. Ferrari ordered their drivers to slow down to minimize the risk of mechanical failure or running out of fuel. Villeneuve believed this order also meant that the cars were to maintain position on the track, with Villeneuve ahead of Pironi. However, Pironi believed that the cars were free to race, and passed Villeneuve. Villeneuve believed that Pironi was simply trying to spice up an otherwise dull race, and duly re-passed his teammate, assuming that he would then hold station for the remainder of the race. Thus, Villeneuve failed to protect the inside line going into the Tosa corner on the final lap, and Pironi passed him to take the win. Villeneuve was irate at what he saw as Pironi's betrayal, although opinion inside the Ferrari team was split over the true meaning of the order to slow down. Villeneuve's expression was sullen on the podium, enraged by Pironi's actions. He was quoted afterwards as saying, "I'll never speak to Pironi again in my life." They proved to be prophetic words, as he was still not on speaking terms with his teammate when he died during qualifying for the Belgian Grand Prix two weeks later.
