The Formula One championship experienced its worst tragedy during the 1961 Italian Grand Prix at Monza, when driver Wolfgang von Trips lost control of his Ferrari and crashed into a stand full of spectators, killing 15 and himself. In 1970, Jochen Rindt won the Formula One drivers' championship posthumously, the only man to do so, underlining the continuing risks associated with road racing. The tragedies highlighted the need for improved safety standards for both drivers and spectators; safety would continue to be an issue throughout the 1960s and 1970s.
