Man that really sucks.
Check out the video above where some guys put an EVO VII on a dyno machine for testing and it went terribly wrong.
For some reason, the EVO started to tug on the restraint. The driver of the car instinctively starts to brake when the car starts to veer off the dyno, but that probably just made it worse.
He was okay after the incedent, but man that sucks for the owner.
Oh yeah, FAIL.
