Ayrton Senna driving the Marlboro McLaren-Honda MP4/5 and Alain Prost in the Scuderia Ferrari 641 lead the field at the start of the Japanese Grand Prix on 21 October 1990 at the Suzuka Circuit in Suzuka, Japan. The Japanese Grand Prix decided the 1990 Drivers' Championship in Senna's favour after crashing controversially into Prost at the first corner put them both off the track.(Photo by Pascal Rondeau/Getty Images)
