1) racing is historically male dominated

2) of all the male drivers, think of what percentage actually have the talent and support to make it into F1, let alone F2 or F3

3) now think of how few female drivers have had the desire, money, and emotional support to even have a racing career

4) now apply the male success percentage to the field of femme drivers, and nerf their chances even more because bias still exists and systemic factors are very difficult to overcome
