Road Rage has noting to do with other horrible drivers. Road Rage is a response people have to their own personal unresolved anger issues and has nothing to do with traffic or other habits of motorists sharing the road or not sharing the road in that case.
You see, there are horrible drivers who are selfish or just incompetent, having a terrible day, lack temporary judgment skills, are in a rush to be somewhere, are distracted on their phones or eating a McDonald's hamburger. I doubt someone wakes up in the morning and says to themselves "I think I will look for woman driving a silver car to harass today". Road Rage victims are random people who are in the wrong place at the wrong time.
It is dangerous to engage a person who is Road Raging. You have a duty to be safe on the road because there are other innocent people traveling, just like you are with families just like you have. No need for angry moves with three ton bullets (vehicles) on our roads.
Yes, it is illegal to be involved with Road Rage. What part of pulling over and searching for something to throw at a motorist is okay with you?? What if you miss and hit another car? What if you pull over in anger and are in a dangerous area, putting other motorists at risk? You see, rage is an emotion that is irrational and unreasonable. This is how people get hurt and even die. Certainly illegal, I assure you.
