Just like I can't understand why it is such a big deal to be in the right lane if the cars in that lane are going the same speed as they are. From what I have read so far it is a mixture of a feeling of entitlement and spite.
From some of your previous posts I don't think we are much different in driving habits. I will do up to 9mph over the speed limit but I hang out in the right lane unless I have to pass. I never get mad at people at any speed in the right lane because that is what that lane is for, I only get mad when I want to pass a car in the right lane and there is someone in the left lane pacing them, making no attempt to pass, with 10 to 20 cars behind them.
Then by reading my posts you understand that on roads like Rt-50 or the beltway, you will almost never find me in the left most lane.
My argument is with a road that has the two lanes in each direction, entrance and exits on the right that cause one to constantly slow and speed up. I choose not to be in that lane, I choose to drive the left lane at the speed limit without having to slow and speed slow and speed slam the brakes because someone enters the lane at 2mph then slowly speeds up.
My typical drive in to work is. 424, speed limit, exact. Rt 50 to the beltway, 63, right most lane. because I am going to exit right onto the beltway and dont want to get caught up forcing my way back to the right at that point.
once on the beltway, its 4 lanes, I hang in the second from the right, at 55mph. I dont use the right due to the on off ramp issues. This leaves the two lanes left of me for the agressive drivers.
But, on 235, You might just catch me in the left lane at speed.
