Is road rage a lack of morals as some have said before? And what is the point of it?
It's probably not the same for everyone at every point in time. The last time I experienced road rage (my own rage, not someone else's)...I was living in the US, owned a pick up truck and was waiting at a red light intending to go straight through the intersection when the light turned green. Next to me, on my left, was a left turn only lane, and a car was waiting there. When the light to go forward turned green, the car to the left of me, in the left turn only lane, stepped on the accelerator, sped in front of me and cut me off, sliding into the lane I was in, instead of going left. I had to slam on my brakes to avoid rear ending him.
Intense anger followed and I chased him down the road, with the intention of forcing him to pull off the road so I could confront him physically. It was a mistake. I didn't succeed and he tried multiple times to have me rear end him by braking hard. After a few failed attempts I could see I would not get what I wanted and I backed off. Later, I remember telling a pastor friend what I had done and intended to do to the driver of the other vehicle. I was ashamed.
There is no good excuse for my behavior - the best option would have been to let it go - but I was very frustrated with certain things in my life at the time and tired of people who I perceived were walking all over me, so it was partly born of a desire to get even - to get even even with a stranger, who had, in my estimation, disregarded my safety for his own selfish ends. So not a lack of knowledge of knowledge of good morals or judgement, just a disregard of them at that time.
