Stirling Moss is an ass....he also complains these days that F1 isn't dangerous enough and borderline suggests death is a 'missed' spectacle from the sport. He's a complete and utter tool with his opinions. No doubt he was fantastic racing driver back in the day but he's not part of the current new generation of F1 drivers and personnel. Ignore him?.
I'm quite involved via friends with the F1 world (although I don't work in it) and it's not as sexist amongst the teams as the TV coverage suggests. A mixture of male and female friends who are aero designers for various F1 teams. Women are most definitely on the increase in F1 and are starting to take over some top positions and high profile engineering jobs. Unfortunately that sort of exposure isn't featured in the TV coverage and is only really picked up on by the hardcore F1 fans. Female fans are one the largest growing sectors of viewership and Bernie's starting to take this onboard and move with the times. He did quite openly court Danica Patrick into F1 and would love her to compete, primarily for the markets it would open up to him.
The glamorous 'sexy' side of F1 is so fake and only exists in TV coverage, most of my mates work long unappreciated hours, there's certainly no orgies of willing girls going on as has been suggested further up the thread. The F1 teams (certainly in the UK) pride themselves on being equal opportunity employers and I actually will stick my neck out here and says it's a little disingenuous to state 'F1 is against women'. That's a drastic over simplification and is only taking into account the drivers. The teams in F1 want to win at all costs, it doesn't matter what gender you are as they'll take the best person for the job. There is a very valid argument in reference to drivers, but not the industry as a whole. It's changed immeasurably in the last few years.
Danica Patrick is an interesting subject. She's by far the most high profile female driver and has some 'success'. She did well to put her car on pole in the Daytona 500 but was poor come the race end and has done nothing of note since then in NASCAR. She did race in Indycar for a few seasons and won a race (albeit due to luck unfortunately) but she caused big controversy with her special aids such as power steering where as everyone else (i.e. the men) are not permitted to run it. She turned her back on the offer of F1, as the level of competition is so intense she wouldn't be able to hide behind mediocre performances. What F1 needs is a 'winning' female driver and not someone who's just fallen short at the top step.
Female F1 drivers in F1 have also inadvertently been set back recently (2012) by the horrible testing accident of Maria De Villota. At her very first time driving an F1 car she made an error and drove into the back of a parked lorry whilst returning to the pits. Suffering terrible injuries (lost an eye and massive cranial fractures) in the process, she was very lucky to live. Suzie Wolfe at Williams does the female cause no good either as she's got the reserve role strictly off the back of her being married to one of the former board members, he racing career to date is awful and she doesn't have enough experience to be licensed to drive in F1, it's a huge PR stunt by Williams. If she was a man with the same racing record she?d literally be laughed out of the sport.
There's no physical reason why a woman can't drive an F1 car, but it is an inescapable fact there is huge physical exertion needed to drive one for hours on end. The biggest strain is placed upon the neck and it's a limiting factor for drivers. Simply due to the natural physique of men there's more likelihood of a man withstanding the constant abuse, but that's only possible due to a strict gym regime and brutal strength. There's simply not enough women going through motorsport that have that 'strength' at the top levels. No doubt if there were more women going into motorsport there'd be a bigger pool of talent to choose from and we might finally get a good enough female onto the grid. Someone who's a proven winner and physically strong enough to continuously drive the cars. At the moment there's a mixture of both out there (plenty of other good female racers throughout the world) but nobody who's the complete package so to speak. F1 is desperate for a female driving star and it's wrong to simple say modern day F1 is against women full stop as there's many throughout the teams doing fantastic jobs day in day out, at the moment it's just lacking the most publicly visible embodiment of that..ie the winning female driver.
Hope that adds a little insight into it.
