Man, you people are a bunch of road rage incidents just waiting to happen. Why do you have this urge to use this large metal object as a moving weapon? If I read your scenario correctly, you're peeved because someone cuts in front of you into the left lane just before you're about to pass another slow driver in the right lane? Are you able to determine this second car's speed before they move into the left lane? Maybe they were going just as fast, and was about to pass the car in front of them before you came flying up. A known driving myth is you're supposed to drive in the right lane as much as possible when you're speeding. The theory is it's harder for a cop's radar to tag you when they're coming from the opposite direction. So you get the fast drivers that weave between the left and right lanes to get around the slower traffic. Want to avoid confrontations on the highway when you're taking long trips?
1) Maintain the speed you're comfortable with as much as possible. If that speed is faster than the traffic you're 'riding' with, stay in the left lane as much as possible. If you come up to slower traffic in the left lane, slow down and 'flash' your lights. This is a known acknowledgement for the driver ahead of you to move over to the right lane at their earliest convenience. Don't ride their bumper. Some people just have a problem with driving faster than the speed limit in fear of getting a ticket. Give them some time to move over. If someone comes up behind you in the left lane that's faster, afford them the same courtesy and move over to the right lane when possible. You can get back into the left lane after they pass you.
2) If you do run into that individual who thinks it's his God-given right to sit in the left lane, pass this person using the right lane. Don't think you're the owner of the 'train'. If someone wants to join in to try and get around the slower drivers, let them. Most likely they want to drive as fast or faster than you. Once you clear the slower traffic, they'll most likely stay in front of you and can be your 'lead duck'.
3) STAY OFF YOU CELL PHONE. Most drivers who create bottlenecks are sitting on their cell phones, oblivious to their surroundings. They change lanes before looking in the mirror, and drive 5 - 10 MPH below the posted speed limit.
Bottom line, you don't own the roads, and neither do the other drivers around you. You can scream, yell, and 'flip them off' all you want to, but all that does is tick them off. Next thing you know, they try and get in front of you, and purposely try to slow you down. You get even madder, and that's when road rage incidents happen. Unfortunately in today's society, half the people out there are packing guns. Just think about that the next time you don't let someone get in front of you in a train. When he/she does get through the slower traffic, they may pull up beside you, and the next thing you know, you're staring down the barrel of a .357. Happy Motoring!
