The thing is, there is also no evidence, that women can get to the same mental-physical long term competetive level as the best F1 drivers. I mean, women can be really fast drivers, but getting to Verstappen's level of driving is unattainable for most men drivers and I see is as plausible, that it just might be out of reach for women. I'm not saying, it is, but I'm also not ruling it out. There are some biological differences between sexes and who knows, where their limitations lie.
I would love to see a woman in F1 but... if she's good enough to be considered a Top Tier driver (or at most Tier 2, like e.g. Sainz). If she was only a decent driver, then I couldn't care less if she was hired or not (like for all other decent drivers).
I see it as a societal issue, but not "women are not given opportunities", more in the way the whole motorsport is built.
If the sport was built like that: give a youngster a car and have them compete in a time trial, and the ones with the most natural talent go to F1, then I can see women getting there.
But motorsport throws children into meatgrinder direct competition on track from the beggining and boys are more aggressive than girls. I found some studies suggesting, that only the level of physical aggression in boys is much higher, but than again in such a close contact sport a physical aggression prevails. Like, you can be an extremely fast, but also a really fair driver, and only lose races, because others pushed you off track. But will the sponsors and teams care for your speed, if you let others push you around?
Honestly, I can't think of a close contact sport, where women can successfully go against men. Although most of these have a greater physicallity aspect than racing.
I feel like that might be a culprit, why so many girls opt out from the sport. Add to this a lower likelihood of competetiveness (likelihood to choose a risky approach), and throw in the money aspect with boy-favourism (not without some merit though), and hence why there are precious little women in the sport.
