If it's rush hour:
If you can't keep up with he guy in front of you get out of the left lane. All I ask in rush hour is you just keep up with the flow of traffic. Stop trying to be a trend setter, if you're going slower than the guy in front of you, you shouldn't be in the left lane (especially in rush hour when nobody's speeding).
Stop taking 10 years to slow to a stop, nobody behind you wants to keep their eyes on your rear bumper the entire commute. Pull up to the car in front of you and stop like normal. Again, if you have 20 open container drinks in your floor board you don't want to spill, and have an absolute necessity to slow to a stop that slowly, do it in the right lane.
Going to be making a left turn soon? That's cool, nobody cares if you turn your blinker on, and get over to your turn lane.
-We care when you do it 4 miles before you're turning and become a trend setter getting to your turn lane.
-By the way, why are you breaking hard before you've even gotten to the turn lane? Get out of the main road way before you break. Obviously its a different story if the turn lane is full, and you need to break early, but 90% of the time that's not the case, and you're just being ignorant and inconsiderate to those behind you.
-People wont let you change lanes if ride in the right lane, so that's why you pull over 4 miles early? Learn to drive, nobody's going to hit you from behind, put your blinker on, and slowly merge in when your turn comes up, they will realize what's going on.
If it's not rush hour:
Get out of the left lane unless you're passing.
If you're passing.... PASS! If you haven't got the balls to pass the guy going 50 mph with an additional 5mph (55), don't attempt it. You probably shouldn't be driving in front of the guy anyways. Nobody wants to sit behind you while you take 5 minutes to pass him.
Pay attention to your surroundings. Don't wait for someone to get right up on your ass before you get over. Why make them waist break and gas to accelerate back up to their cruising speed?
My Opinion when it comes to non rush hour times of the day:
You might have the right to drive in the left lane, but you're being a jackass, sooner or later someone will run you off the road. If the cops don't start enforcing this shit, the road ragers will step up eventually.
Let's see, arguments against:
You don't have to move over because someone's speeding? Bullshit, read:
