It was unclear from the article whether or not the victim had cut off the enraged driver, and the way I read the article, it implied that if he did cut the attacker off, it wasn't intentional. I've seen plenty of dumb moves in traffic that probably weren't intentional, and I've probably been guilty of a few myself. Bottom line is that we don't know. We do know that an angry driver walked up to a car, busted out the window, and threatened the occupants. To me, the victim would be reasonable to fear severe injury or death. Driving away, if possible, is preferable. However, the original story that I read did not say whether or not that was an option.
