I'll concede your first point (about this last incident), but I think she has a great car. She drives for one of the best teams that compile information from two of the better drivers in the sport. Tony Kanaan has won at least 6 times (5 times more than Danica) with at least that many top threes driving the same car (to the extent that the cars can be the same)during the exact same time period.
If the car's not performing better, she only has herself to blame. As I said in an earlier post, Kanaan (and all the great drivers) knows how the car works. He can tell the chief engineer precisely what's wrong with the car making it much easier for the engineer and the technicians to set-up up the car for maximum speed at optimal handling. If Danica's car isn't performing as well as her teammate's, she only has herself to blame. But with her ego, you'll never hear her say that.
In fact, I can't ever remember he saying anything, but especially her performance, was her fault. It's always somebody else problem or mistake. That's my problem with Patrick.
The cars have gotten too complex to not know something.
