I think she has proved what she can do when she has a fast car...but IMO that is all the difference...she has to learn how to "trade paint" before they cut her lose...
...If you've ever been close to open wheel racing...learning to "trade paint" does not come easy...just ask J.M.
Hard to take her serious when she does stuff like this (or the go daddy ads). I could see if she did it once for charity but it seams like it's her fall back position.
I don't blame her for using all her assets. More power to her, on and off the track. She would be the only reason I would watch car racing, or CMT Awards or anything else she would appear on.
