The women in pole position

Fact: Formula One is a mixed-gender sport. It also happens to be one of the very few where men and women can compete together on the same grid. So why is there so little female representation, with no woman driver in F1 since the 1970s? And why are the likes of Ayrton Senna, Alain Prost and Lewis Hamilton household names, whereas Maria Teresa de Filippis, Lella Lombardi and Susie Wolff are little known outside racing circles? (And who are famed for being the first woman to race in F1, the first woman to score a point in F1, and the first woman to participate in a Formula One weekend since 1992 and who now heads up the F1 Academy, which aims to increase female participation in the sport.)
