Stupid question from someone not into this sport at all. Why is there a division between men and women in this sport if the thing "actually" competing is a genderless vehicle?
There's nothing in the rules stopping women compete in F1 or the lower categories, its just that its such a male dominated sport. The idea behind W series was to put a spotlight on women in motorsport and hopefully generate interest and ultimately get more women / girls partaking in the more junior categories / karting.
