We can't help but wonder how many road rage cases are settled just because of GoPro.

One incident occurred this past weekend on the corner of Pacific Avenue and 24th Street in Yuma, Arizona, when a motorcyclist said he weaved in and out between several cars, and one in particular whose driver didn't take too kindly to the high speed maneuver and decided to get out of his car and punch the motorcyclist"?in his helmet. Yeah. That's gotta hurt.

The guy continued on a rampage, shoving and even attempting to punch the motorcyclist's girlfriend. The motorcyclist did his best to subdue the attacker, knocking him down to the ground and pinning him there until other drivers were able to call the authorities.

Check out this intense video that will make you believe in the power of GoPro.
