This is why you should be nice to everyone. With three laps to go, Mark Martin and Juan Pablo Montoya raced each other hard for the lead in the Sylvania 300. Montoya could have bumped or wrecked Martin, but he didn't. Why? Because Martin is the closest thing the former Formula 1 driver has to a mentor and crossing that line is something even a hothead like Montoya knows he can't do. One race down. Nine to go. And Mark Martin is your Chase leader.
