Why there are no women F1 drivers?

Formula One is a male-dominated sport. Most of the mechanics, engineers and other staff are male and there has been no female racing driver since Italian Giovanni Amati tried to qualify for races in 1992. It has often been argued that it is only prejudice that has prevented female racing drivers being successful in Formula One, but that is only part of the explanation. The physical demands of a Grand Prix car calls for massive upper body strength, something which women�s bodies are not designed for. It has also been argued that the cold-blooded aggression needed at the top level of the sport is helped a lot by male testosterone.
