Two drivers literally drove each other crazy in Indiana on Saturday when a speedway race escalated into a combined demolition derby and fistfight that only ended when one driver was tased.
The footage, shot at the Anderson Speedway 35 miles from Indianapolis, shows a pair flying off the track after one clips the other on a tight turn.
Furious, one of the drivers then takes his vehicle up to his opponent - then over him. Things go downhill from there.
