Fewer sports feature more intensity than racing. High speeds, bumper-to-bumper action, and sometimes violent collisions. Sometimes for race car drivers, things reach the boiling point.

Case in point: over the weekend at Bowman Gray Stadium in Winston-Salem, North Carolina, where driver Derek Stoltz was in a war on the track with an entire family - the Robertsons.

First Stoltz wrecked race leader Bryant Robertson, and later tangles with Bryant's brother Mike.

Mike wasn't about to stand for this kind of insult to his kin, and so he decided to take matters into his own hands when Stoltz came by on the track, forgetting one important thing: Stoltz was in a RACE CAR and he was on foot.

The results?  Predictable...
