Want to know what's more dangerous than a car crash? A car crash followed by a full-on fist-fight, since you ask.
And - what d'you know? - US sports fan Jeff Pile witnessed exactly that (albeit from quite a distance) during a day out at the Sportsdome Speedway in Clarksville, Indianapolis.
Keep your eyes on the back stretch of the track in Jeff's video (above) and you'll see how a brawl broke out after one driver intentionally rammed into another car. Honestly! This isn't the kind of thing we want to see happening on race day, is it? But then again, it does rather liven things up for the neutral observer...
