I read it. I have never gone(and will never go) to the point of the cyclist in the article. While the cyclist was expressing disgust, they crossed the line, when they punched the offending vehicle, regardless of the negative nature of what the cyclist said to the motorist. Then the passenger(and probably the driver) crossed the line, when they threatened to kill the cyclist.

The cyclist in the article was FRAP'ing to the curb, in my opinion inviting the threat from the vehicle's passenger to come to fruition. The article mentions how the cyclist was squeezed to the curb. I try to not let that happen, by 'taking the lane'.
