Best in-car: Clint Bowyer goes off on ‘that dumb (expletive)’ Vickers

Clint Bowyer was an unhappy camper Sunday at Sonoma Raceway.

Clint Bowyer is livid following a collision with Michael Waltrip Racing teammate Brian Vickers. NASCAR’s most popular driver, Dale Earnhardt Jr., wonders aloud "what the (expletive) I was doing there," after wrecking Matt Kenseth. And almost everyone is less than happy about the way his car is handling around the 1.99-mile, 10-turn Sonoma Raceway road course.

You might want to put the kids to bed before turning up the volume, because you’re guaranteed to get your ears full in this Sonoma edition of "Radioactive" on NASCAR Race Hub.
