> We’ve all been there: Some jerk cuts you off on the highway. You lean on the horn, scream abuse. You want to get out the car and kick the @#$% out of the bozo’s SUV.
"The AAA Foundation for Traffic Safety found that between 1990 and 1996 road rage contributed to 218 deaths and 12,610 injuries. The study analyzed 10,037 police reports and newspaper stories about traffic accidents that led to violence. What's more, AAA found that road rage incidents increased nearly 7 percent each year within that six-year period."
Not sure what you're trying to say, exactly. "There is proof that road rage exists"? OP didn't say "Road rage doesn't exist", he said "It's not universal". A universal quantifier ("all" or "none") can be disproven with a counter-example (op to article), an existential quantifier ("some" or "not all") can't (you, if I understand it correctly, to op).
Yeah. I know road rage isn't rare, but some people talk about it like its normal behavior. Most people I know, including myself, don't let minor annoyances get to them like that.
