This go kart driver brutally attacked his opponent after being pushed off the track, and crashing
a short while later. With footage taken from his own Go Pro, we get the rare example of someone effectively filming their own crime, as this level of retaliation no doubt landed this driver in some form of trouble.
While the initial bump that sends the driver off track is perhaps aggressive racing, it is not egregious by any means, and could conceivably just be considered a racing incident where neither driver left the other enough space. The resulting retaliation however, where the driver purposefully spears the other, then attempts to strangle them, and eventually punches them twice hard enough to knock off their visor, is downright incriminating. The other driver surprisingly seems completely taken aback, not even defending themselves during the incident. Racing isn't hockey. The gloves stay on, and retaliation happens on the track.
