Have you seen video of Brad Keselowski's crash this week at Watkins Glen? It's a frightening reminder of what can go wrong in a racecar.
Keselowski addressed Tuesday's crash during a media session at Pocono Raceway, where he and Sprint Cup drivers are preparing with weekend racing.
Keselowski was not injured in the crash, but video shows he caught a break. His car went into a barrier head-on. And on Friday at Pocono, he had an interesting take on repaved tracks and their inherent problems.
What happened? Keselowski said a brake line on his car failed.
