Clearly it shows an attention to balance and stability, like any good racing driver.
I haven't seen Danica posing for those kind of photos in a few years. She's certainly proven herself a serious racer. When she left Indycar she was top driver in points in her team, though I haven't kept track of her NASCAR adventures.
That happened earlier. In her last year in Indycar (2011), she finished behind 2 of her 3 teammates in points, though all 3 of them won a race that year. Her best finish was 5th.
