The 1989 Japanese Grand Prix remains one of the most infamous races in Formula One history. Senna took pole position, with Prost in second. Prost jumped Senna at the start and was leading into turn one. Senna fell back and positions remained unchanged. On lap 46 out of 53, Senna, desperate to pass Prost to keep his championship hopes alive, tried to overtake him at the last chicane, but Prost closed the door and the two collided. Prost stated that he did not believe he was responsible for the collision and complained that Senna's overtake was dangerous in attempting to go for a gap that was no longer there. After the collision, Senna had stopped off the track and waved the marshalls over to give him a push-start – within the rules if a car is deemed to be parked in a dangerous position. Senna re-entered the race via a run-off-road and made it back the pits for a new front wing, managing to re-take the lead in the final few laps, crossing the line first. A long period of silence ensued with podium regularities conducting without Senna. Senna was disqualified for re-entering the track illegally, meaning he was ruled out of winning a second title. Senna made a case to the Fédération Internationale de l'Automobile (FIA), however his case was dismissed swiftly. Senna would continue to protest throughout the off-season, with his ultimate battle just beginning to heat up.
