In this video, two men encounter each other in a traffic incident and things get a little heated as they argue with each other in the street.
The issue seems to disperse briefly when pedestrians show up and appear to try dispelling the tension, but the confrontation spikes again as one man gets out of his buggy to attack the other.
Their fight progresses until the other man picks up a cinderblock and knocks his opponent to the ground with it.
Yikes, that's pretty extreme.
