The 1978 Italian Grand Prix at Monza carries so much weight of consequence that any description of it as a motor race feels inadequate. It was a motor race — the fourteenth round of the World Championship, held at the cathedral of Italian motorsport — but it was also the place where a driver died, where another walked away from the sport for good, and where a championship was won in circumstances that the winner has never been able to celebrate without qualification.
At the start, on the approach to the first chicane, a massive accident erupted in the midfield. Cars ran into each other; debris flew across the circuit; vehicles caught fire. In the chaos, Ronnie Peterson's Lotus was struck and came to rest against a barrier, both its front wheels torn away. The Swede, who had been the fastest driver in Formula 1 that season and who had subordinated his own championship ambitions to those of his teammate Mario Andretti under team orders, was extracted from the wreckage with severe leg fractures. He was alive. He was taken to hospital in Milan.
Niki Lauda, twice World Champion, had arrived at Monza in what was understood to be his final race weekend of the season. During practice, he had decided that the risks of racing — a calculation he had been revising since his 1976 accident at the Nürburgring — were no longer acceptable to him. He did not start the Italian Grand Prix. He returned to his motorhome, changed his clothes, and drove to the airport. He never raced again that season. He retired at 29 years old, one of the fastest drivers of his generation, having decided that the sport's costs exceeded its rewards.
Mario Andretti won the restarted race. He was confirmed World Champion. Ronnie Peterson died in the early hours of the following morning from fat embolism — a complication of his leg injuries that had not been anticipated. Andretti learned of his teammate's death and his own championship simultaneously.
