I have a death wish while driving.

I've noticed that I cannot tolerate rudeness and aggression from other drivers while I am driving. I'm not sure why I behave like this; most of the time I simply ignore such behaviour and move on. This pattern gets thrown out the window, though, while I am behind the wheel. I present to you 3 cases:

I am in a parking lot. As I'm inching forward in a parking lot jam, trying to get home, a car in a lot in front of me starts reversing out of a parking spot, getting in my way. I wait until the car clears the spot and moves on. While I am waiting, the impatient driver of the SUV behind me starts gesticulating wildly and honking me. I get irritated, so I flip him the bird. He promptly replies with self-same gesture and then proceeds to hound me ALL the way through the parking lot, hitting the horn as he goes while he tailgates my car. I eventually get tired of the whole thing and manage to give him the slip.

I am once again in a parking lot. The car in front of me starts parking in an inappropriate spot, blocking my way. I get annoyed and frown very hard at him. Suddenly the driver rolls down the window and starts gesticulating wildly at me, at one point even lifting his steering lock and shaking the contraption at me. I am puzzled, but pay him no mind when he finally drives away. After parking my car, the same driver stalks towards me and starts yelling obscenities at me. Suicidally, I insult him right back (in a far more articulate and sophisticated fashion, of course). Now he's steaming mad and rushing at me with his fists balled. Suicidally (again), I stand my ground and prepare to get caught up in a fistfight. (I think I did this because I had a female passenger with me, and had this momentary need to protect her from the harm that an apparently crazy motorist can visit on nearby onlookers.) This seems to give him pause, and he stops his violent advance. Negotiations reopen, and we discover that there was some "miscommunication" (obviously a face-saving gesture). He thought I was insulting him in my car while he was trying to maneuver out of a tight spot. I assure him I was not. Apologies are made and the situation blows over.

I am driving down the highway, about to shift into the higher-speed middle lane. I check my mirrors, take a quick look to my right and start switching lanes, signal lights flashing. A really fast-moving vehicle from way back (right lane) suddenly switches to the middle lane and before you know it, is blaring his horn at me for obstructing his way. It's too late for me to switch back into my original lane, so I ignore him and finish the lane switch. The driver is incensed by my brazen move and continues to honk at me, flashing his high beams. When he gets no reaction, he draws up parallel to my car to do...I don't know what. Instead of ignoring him, I flash him a cheery smile and a wave. This really gets his goat. This uncouth middle-aged man then continues to tailgate me nearly all the way to the office, obviously going out of his way to do violence onto my person. I briefly considered driving straight to a police station, but instead manage to give him the slip by making an unscheduled (and therefore, dangerous) turn, leaving him stranded on the highway.

If I keep this up, one day this will all end in tears. I really need to learn to be less impulsive on the roads.
