It should be a law that you're legally allowed to bump people off the road who drive like you do.
There was already a similar discussion about this topic awhile back, but I'll reiterate ... get the eff over. No one cares if you think you're going fast enough.
If this is a 3-lane highway ... you need to get the EFF over ... now. There's 2 other lanes for slow drivers to travel in.
Around here, the stated speed limit is typically 65 mph on 3-lane highways. But everyone travels at least 80 mph ... in the slow lanes. 80-90 mph is the cruising speed. This is, of course, when there isn't so much traffic that everything is slowed down (by people like you, no doubt). Again, this isn't the "hey, you wild and crazy reckless kid" speed ... this is the normal flow of traffic speed where everyone is comfortable.
Almost every a-hole you see in the left-most lane travelling slowly enough that traffic is building up behind them is driving a junker, and looks homeless. Because they don't know any better. They're awful, dumb, inconsiderate, uneducated human beings. They need to go. They force everyone driving at the typical cruising speed to move to the right to pass them ... this creates potential hazards that need not arise ... hazards like trying to pass people in a lane where people are moving slower.
If it's a 2-lane highway, it gets more interesting because, inevitably, there are more a-holes like you destroying the flow of traffic, and fewer options to get around them, so those highways are usually jammed up with slow moving lanes, while everyone dreams about setting the people who are causing this traffic on fire, and then mockingly tell them to "move slow now, turdnugget." So, in these cases, you just have to relegate yourself to the absolute torture that is heavy traffic. But in the cases where there is sufficient room in which to maneuver on a 2-lane highway, your TRAVELLING lane is the right lane. When you approach someone from the rear, you get over, pass them, and then get back over into the TRAVELLING lane. In no circumstances do you stay in the left-lane unless you are actively passing someone. With one exception ... if you have room to get over to the left as you approach an entrance ramp, you do so, to allow those folks an easier time getting on and up to speed. Then you get back over.
