Don't understand why/how people let stuff like this get out of hand like it does... some people just don't seem to have enough emotional stability to think rationally when things happen.
While living in Houston back in the early 90's, I was waiting to turn in the middle of an intersection. I was making a left turn, light turned yellow with cars still going through, and also a couple of cars raced through after it had already turned red. So I'm in the middle of the intersection, can't back up... I go ahead and make the left turn, and a car coming from my right had to slow down just enough to accommodate my intentions.
The driver behind me starts blasting his horn, blinking his lights, flipping me off out the window. I returned the gesture. So another light is coming up. He pulls up to my left, and he's yelling at me through the window while we're waiting at that intersection. "Learn how to f***ing drive, you idiot!" he yells. I yelled back to him through the window, "pull up to the curb and we can handle this face-to-face if you want!"
So I pull up and pull over to the curb, he pulls up behind me. I get out of my car and walk over to his car. "Did you not understand the situation I was in there? Is it asking a little too much to show a little courtesy" I ask him. He's still sitting in his car.
He says, "You're not from around here, are you... let me explain something to you - you suck at driving, and you're stupid for pulling over and getting out of your car. You know I've got a 9mm pistol here in my glove box? Do you know how lucky you are that I've got too much to live for instead of going to jail for shooting your stupid ass?"
At that point I apologized, walked back to my car and went on my way. Lesson learned.
Other people's lack of patience and courtesy ain't worth dying over. Every time I start feeling mad and upset over another driver either slowing me down because they're not driving in the slow lane or tailgating me with nowhere to go - I remember that day. It just ain't worth dying for.
