Not sure of what happened with these guys but I will tell you I've had people jump out of their car and come at me, I just drive off. Even if I have to run a red light. May make them even madder but by the time they get back in the car and attempt to find me I'll be long gone. and no I won't jump out of a car and confrnt someone in that type of situation.
Rule 1. If someone flips you off, ignor it. They are showing their imaturity
rule 2. always leave yourself an out when driving, if you can't see the bumper in front of you then you can't get around it.
Rule 3. anytime there is an altercation, 911 is your friend even if you think it's over.
Rule 4. You are carrying a weapon, use better judgement that the next guy, it might save your butt by avoiding the whole situation.
Had a trucker chase me off the interstate once, not sure of what his problem was and didn't care, came up behind me flashing his lights, honking his horn and being a total jerk, I went up the ramp, he followed, so at the stop sign I paused just long enough for him to start slowing down good and a gunned the crap out of my truck, buy the time he was able to get through the intersection I was long gone. He might have just been having a bad day and I was theone he was going to take it out on but I spoiled his plan.
