There's epic fails, and then there's this.
The people in the car shooting the dash cam video are in stitches. And they are very, very loud. That said, they have very good reason to be laughing this hard. And as hard as they are laughing the guy driving this late 1960's Dodge Dart is crying. A combination of extreme torque and a bad welding/installation job, meant that when the muscle car tried to impress by flooring his ride, he ended up failing in the most epic way imaginable: with the rear axle of the car breaking loose.
Next time you decide to mash the pedal at the lights, spare a moment for this guy. Note: You might want to turn the volume down before hitting play.
