Best in-car audio: Danica Patrick gets fired up after a bump from her boss

It’s time to take a listen to the best in-car audio from Kentucky Speedway on this week’s edition of NASCAR Race Hub’s "Radioactive."

Danica Patrick is mad at her boss, Tony Stewart. Kevin Harvick is mad at his pit crew … again. And Brad Keselowski loves horses.
