Don't bother: I only react to people if they do something stupid like cut me off or if they are in the left lane going 105 km/h and people want to go 120+ km/h and when I need to pass (I live in the middle lane), I can't because of morons like that.
I usually just give them the Italian hand and that's it, but it rolls off my back and I don't hold it in.
Other people though? Man, people need to mind their ******* business and just worry about themselves. I am an, "ascended," driver if you will: between videogames, the tiny bit of Karting I've done and the fact that I study the road and my car (and how to live within the, "ecosystem," of the road), I'm not a slow pleb like the VAST majority are.
I stick to 10 km/h over the limit on every road, weather and conditions permitting. It's fast-enough that you can still be safe, not get nabbed by the police and you save time driving like that.
But when people are going 50 km/h in a 60 zone, you can bet your ass I will pass you. In almost every situation, the person flashes me, gives me the finger, just something, because I passed them.
IT'S LEGAL, IT'S SAFE, IT'S A PERMISSABLE ACT, so why are you angry?
A few months ago, there was someone turning left and stopping traffic as a result. There were 2 cars behind them and I was the 3rd car.
So I decided to go off on the shoulder and pass them, as we weren't moving, I was in a hurry and it was completely safe to do so.
So I did and about 3 seconds after I was clear, the guy turned left. I see in my rearview that the second of the cars waiting (a pickup truck) passed through a solid, double line (so illegally passed) the first car waiting, went right up my ass and then at the next light, I turned left, they went straight.
I could see out of the corner of my eye, him rolling down his window and he proceeded to yell at me for about 15 seconds and he could hear that my music was very loud, but he continued to yell and I didn't look at him for even a second, driving away when my advanced green came.
The funny thing is, if ANYONE made the same maneuver as I did, in the same situation, I wouldn't even look at it twice. It's like people take vehicle movements and actions purposely against them and they decide to use that to get their anger out.
People are F'D.
