Why do some people experience road rage

I saw it this morning . This crazy woman acted like her rear was on fire zipping in and out of traffic . She tried to cut in front of me and my 4x4 and I wouldn’t let her in so she laid on her horn , flipped me off , and rolled down her window to yell at me . I rolled mine down and yelled for her to pull over so I could “ put my F’ing foot in her ass “ 😳😳😳🤭😂!

I would have looked funny doing that in heels . 🤦🏻‍♀️
