Where did this myth start that Patrick is just some hot babe who can't drive? (That would be Milka Duno.)
She's been in the top 10 in Indy every start except for 2008, and she got her car from 23rd (as part of Andretti's disastrous qualifying) to sixth this year. Her points finishes have been comparable or better than her teammates' totals. The only time she was outshined was 2008, when Tony Kanaan finished third, and she finished sixth. To say she's been on "big-money" teams is also a myth, because the biggest of the big money is Penske and Ganassi, and everyone else is racing for scraps.
Sure, she gets a lot of hype because she's an American female racer who can actually race. That's what happens when you're unique. That Patrick is marketing-savvy helps, for sure. But like with Tiger on the golf course, there are a lot of fans who watch just to see how she does. That's just a fact.
And if you're going to criticize Patrick for getting rides "only" because she's a woman, you have to criticize all the drivers who get rides "only" because their fathers and/or grandfathers raced.
My criticism of Patrick would be that her move to NASCAR is all about marketing rather than winning. If she wants to win consistently, she would be better off concentrating on wringing all she can out of her Andretti car and hoping that someday Penske or Ganassi will bring her in. The NASCAR move has marketing savvy, but it's a long hill to climb up switching from open-wheel to the racing taxicabs.
