Seriously, people need to start using their

' brains and stop trying to screw up traffic. Look at the posts we have from people that intentionally sit in the left lane thinking they are responsible for speed limit enforcement. Then we have people that insist that it's not only illegal, but immoral to speed by even 1km/h, regardless of what it might do to the flow of traffic. Stop obsessing over the number on the sign and try to be considerate and keep traffic moving smoothly.
I'm not advocating burning through traffic at some insane speed that is beyond your abilities, but seriously, if I'm in the left lane passing someone, and someone traveling faster than me is gaining on me, I speed up to match their speed, and move right as soon as possible. I make sure no one slowed in the left lane thanks to me.
When merging, match or even slightly exceed the speed of the traffic you're merging to. Laws, rules, whatever, I don't care. I just know that this allows traffic to keep moving and there is no sudden conga-line of pissed off people.
The right lane is the normal driving lane. You move left to pass and move left to let people merge. What pisses me off is when I move left to let people merge, and then the jerk-offs intentionally block me from moving back right to let faster traffic by. Oh, no, they're going to tailgate the person in front of them just to make sure I can't get back in. Why are people such assholes when they drive? There are posts in this thread about people enjoying making others angry. Christ, what is with that?
