Sometimes it seems as though people seek to find reasons to down grade Patrick. The most frequent two are: 1.) She has used her looks to get rides that she wouldn't have gotten otherwise, and 2.) She has only won one race despite being in decent machinery. And there is truth to both of these arguments.
However, I think we tend to forget two things also...
how difficult it is get good rides, and the fact that it is MUCH more difficult for a woman to do so in male-dominated auto racing.... and...that winning races is always tough to do, good rides or not. I have seen so very many put Patrick down (even more than in this forum) in some very cruel, sexist, and ignorant ways. Understand that even if her looks have helped her grow her career, this is a driver who was good enough to get this far in the sport... no amount of good looks could overcome no talent at all. Patrick came within a couple of laps of winning the Indy 500... after nearly 500 miles of driving at speeds well over 200 mph. People with no talent do not do that... regardless of gender. Just as drivers with no talent do not qualify on the Daytona 500 pole, wrestling around a 3400 pound car... a crude car according to most on the forum here.
Is she going to win the race? I doubt it. I would take the field against ANY one driver, on or off the pole, the odds are just too great to bet against the field. As has been pointed out, the race is seldom won by the pole position. However, we accept that with most drivers (ie male), and somehow we all know that if Patrick does not win, some will be saying "I told you so, she just can't cut it".
As for the use of her looks to promote herself, I say why not? As several have pointed out, many male drivers have done the same thing, some even in sexy poses. Is it fair to hold her to a different standard? We have seen many beautiful women in a multitude of careers do sexy photo shoots, and most of us do indeed look at the pics... yet, we hold that against Patrick? I think there is a double standard being applied often, and often there is a "male superiority" factor not being able to accept the idea of a woman being competitive in top levels of racing disciplines.
Patrick is not perfect, nor is she the equal of the top racing drivers in NASCAR on the track... yet. She can be tempermental and is certainly willing to confront others when she feels she is being wronged, on or off the track. That does not sit well with some of her fellow drivers, but then, it did not sit well when Montoya or Keselowski also gave it back when it pushed as they learned the "ropes" of NASCAR racing either.
I wish her luck, if she should win, it would be great for her, her team, and greater still for the sport of auto racing, not just NASCAR. As was said before, NASCAR, like IRL before, has also used Patrick greatly to their benefit. There is a reason why Danica Patrick is the name on the tongues of so many racing fans instead of some of the other female drivers who are in the sport.... the woman CAN drive...AND looks good.
Ciao.

I would imagine Danica has no problem getting a good ride.
