In 1978 Patrese very nearly won Arrows' second race, the South African Grand Prix, until engine failure forced him to retire 15 laps from the end. He subsequently took second at the Swedish Grand Prix behind Niki Lauda's Brabham BT46B "fan car", in its only appearance before being withdrawn. However, his driving style was perceived by some established drivers, such as Ronnie Peterson and James Hunt, as being over-aggressive. Later that year, at the Italian Grand Prix, Patrese's reputation for aggressive driving was blamed for a first lap major incident. In part, one of the causes suggested was a premature start by the Monza race director, leading to cars at the rear of the field catching up to those in the midfield that had been fully stopped when the green signal was given. This being said, Patrese, Peterson, and 8 others were involved in a 10-car pile-up before turn one, causing a stoppage of the race. Peterson, whose injuries from the chain reaction wreck were not in and of themselves life-threatening, died from an embolism the day after the Grand Prix.
