Wait? What? References? Last time I checked there were hardly any women in racing in both generations, and certainly not enough to necessitate that kind of quote.
Michele Mouton, 4 WRC round wins, 2nd overall in 1982, 9 podiums, everything in Group 4 and Group B machinery. Also important to note that she didn't win the rallies that "no-one" participated in, she won against drivers like Walter Röhrl, Henri Toivonen, Hannu Mikkula, Björn Waldegård, Timo Salonen, Ari Vatanen and Miki Biasion. Also with a female co-driver in Fabrizia Pons. Also, 6th over in Dakar, while in reality driving the service car for the main drivers in the team (carrying spare parts etc.)
Lyn St.James, three class podiums (and one win) in 12hrs of Sebring, two GTO class wins in 24hrs of Daytona, remember the GTO cars back then were cars with massive engines, 700HP, 1200-ish kg. ROTY at Indy 500 in 92 (her first Indy race what so ever), granted - she was the only rookie who finished, but as we saw this year ROTY is awarded for the whole Month of May, not solely the race. (Other rookies to note that year, Paul Tracy, Jimmy Vasser and Nelson Piquet). Also a 2nd place in the 24hrs of Nurburgring.
Ellen Lohr, while never being a world class driver, she was more than respectable, and over seasons beating drivers like Jacques Laffite, Franz Engstler, Uwe Alzen, Keke Rosberg, Yannick Dalmas and Emanuelle Pirro.
Anne-Charlotte Verney, 5 class podiums at Le Mans from 75-81, including one win, which along with three other podiums came while she was entered in her own team. Granted, when she did Dakar she got lost and went missing for five days having to be rescued by the military (queue women and navigation joke)
Janet Guthrie, 5 top 10 in 33 Winston Cup races in the late 70's (that's one less than Danica have had in well over 150 races)
Patsy Burt, first woman who won a British National title, 42 victories, well over 150 class wins and having sat over 20 British records, and quite a few international ones when she retired in 1970.
In the 20's and 30's you also had women getting good results, and setting records, but that's a tiresome research job, but Mrs Victor Bruce is a really good read! Good read is also the story about "The woman who got women banned from motorsport" after beating men in "men only" races. Joan Newton Cuneo.
That's just a sample of the women who drove when the cars were "proper, without aids, and only the best of the best could do well".
A lot of people in this thread have gone all out to justify how women can be as competitive in F1 or any motorsport, but the results just aren't there to back up the claims. There are women driving now in various motorsports, but none of them are really winning any championships and some not even a single race. This does not bode well for the theory that they can equal men in motorsport much less F1.
That's like saying Daniel De Jong, Alfonso Celis jr, Rene Binder, Keyvan Andres Soori, Damiano Fioravanti, Akash Nandy, Bruno Baptista, Zaid Ashkanani, Adderly Fong, Mitchell Gilbert and many many more are proof that *insert reason* will prove that *insert reason* cannot succeed in motorsport.
It will be interesting to see how Magda Andersson does this season, when she was 17yo she was 4th in the European Rallycross championship, Touring Car class, when she was 18yo, she was 2nd overall. This season, she is 19 and is in the European SuperCar Championship. It wasn't a success in the first event, but it will be interesting.
But then again, the sample pool is so small, take wikipedia, which is far from a full source, they have indexed 148 pages about "Female racing drivers", that's all from the obscure young kids racing in Latvia (!) to ladies that died in the early 1900's. From that small sample pool, we are trying to match up with the massive amounts of men, it's a bit like saying gay men cannot compete at top level motorsport, because the only gay F1 driver didn't manage to score points.
