I seen an interview with Danica this year after an average qualifying effort in that IRL car, and she is probably the cockiest girl race car driver I've ever seen. She cut her team down into shreds for a 10th place qualifying effort saying, "yeah, I'm very disappointed with that. We should be alot better than that....(blah blah blah)." She's setting herself up for some great disappointment coming into NASCAR.
She's not going to adapt well to stock cars...the only one who has found success that way was Tony Stewart.
