I edited my original comment above I think I got a bit too heated and on second thoughts sounded very unfair. But yes we can discuss that in the past when racing cars were favourable to anyone there were the occasional female F1 driver, but it's very rare and these days you need to be totally an athlete to handle a 1000 bhp beast.
I am also in favour of a womens only F1, even if the cars are a nerfed version, because the opportunities it would give for young women in motorsport having their own complete series would be a big win. I don't think there has been such an exciting time for motorsport as people switch on to F1, W Series, Indiecar and NASCAR or even taking interest in karting. All of which have supported and featured talented women drivers.
I think the executives of the FIA need to make a firm decision, do you want to segregate, or not. Make your minds up. Personally and it's only my opinion, as a fan who follows many motorsports especially W Series right now, a W Series F2 and F1 wouldn't be a bad thing like I stated above for women in motorsports, it would grow overtime, such as the support for womens football, on the global stage, as part of the main F1 event and help springboard so many careers and bring so much entertainment to us fans allowing young men in the academies trying to work their way up to F1 have a better chance for one of those coveted seats at the top.
