Average weight advatage. Most competative drivers drivers are about 50 lbs heavier than her. The ones complaining weigh about 200lbs. Which means the good drivers have the same advantage against them as Daniaca has against the drivers not complaining.
And if you are going to make the weight issue "fair", what about corecting for lower female upper body strength? Which would be an issue even if Danica wasn'r a tiny slip of a girl.
Or we could ignore the whole thing and just let them race.
And as the picture rule applies
Oh she has "man" hands (posted so the people who notice that won't have to post)
