I don't much care if women race with the men. At the end of the day, I want good racing, and the gender of the competitors are irrelevant to me. However, I will say given the physicality of riding a 1000cc GP machine versus a Moto 3 or even Moto 2 machine, is likely going keep women from ever competing at that level. Can you see a female being able to match Marc Marquez? Never.
My only real issue with women in motor racing is the media chases after the attractive ones, and ignore the one's who have the real talent to compete with the men. In the shortened 1975 Spanish Grand Prix, Lella Lombardi became the only woman to EVER score a point in a Formula 1 Grand Prix. It was 1/2 a point due to the race being stopped after Rolf Stommelen's car crashed into the crowd. Irregardless of it being a shortened race, this was at a time when the cars were running no power steering, foot clutch manual gearboxes, bias ply tires, and cars that beat the piss out of you.
The focus on media hype stars like Danica Patrick does such a disservice to what that Lombardi did in 1975 against a field that included the following:
-James Hunt
-Jackie Ickx
-Niki Lauda
-Mario Andretti
-Emmerson Fittipaldi
-Ronnie Peterson
-Mark Donohue
-Jody Scheckter
-Alan Jones
6 past and to be future world champions were on the starting grid that day at the Montjuïc Street Circuit. Danica Patrick won a fuel-saving IndyCar race at Motegi. Okay I guess. She has never done anything since when it relied on something more than sheer luck, such as actual talent. Plenty of other females remain buried as long as same halfway attractive female competitor exists.
