She's 45, guys. She is not in her athletic prime. There are only 16 drivers in the entirety of Cup history that won a race at age 45 or after. Out of 208 names, that makes 7% of the total. She is also not going to get significantly better even if she has more experience, again, because she is already 45.
I wish her well but I'm also of the mindset that I wish the money being used to keep her career afloat was being used to float a female driver under 30. They exist and are predominantly racing on ovals.
