To have a successful female F1 driver you really have to change society.
F1 capable drivers are scarce, and with the ammount of girls into motorsport nowadays, plus the money requirements to develop a career till F1, find a girl that is talented enough would be really rare. Let's say if 1/100000 male drivers is good enough for F1, you have to find that 1 in 1/100 in case of women.
The "sexism from the crib" we have now won't allow the numbers. If we encourage small girls to be active and do sports and not just raise princesses that like pink and have as biggest goal in life to look good for boys, maybe there is a chance of having the same representation of woman in Motorsports that exists in life (around 54%). Then would be more possible to find some of them that are talented enough for F1, despite the physical strong points of women may not be the most required for F1.
I'm obviously generalizing, but there is no doubt the number of girls that start practising sports is lower than men, and woman focused on sports that keep practising in adult life and try to reach professional goals are even less, in big part motivated by the lack of founding most feminine sports have, but in case of Motorsports a talented woman may have some advantages because there is commercial interest to have a woman in the top categories.
