I've nosed out to the right to threaten to clip them as they go by....and I'll speed up to tailgate the guy in front so they don't come back over in front of me...
Sorry man, but that is a type of driving that can be a problem and unsafe... And I'm only talking if the other drivers are going the speed limit and not cutting off people when they merge or wait too long and cut over after the lanes have started splitting etc. If there are open lanes, they should be used. I don't get why people get so angry with other drivers where they feel the need to personally speed up and/or swerve against them.
Everyone needs to get to work on time etc and I'm not defending jackass drivers, but there are a lot of drivers out there that use lanes legally and merge into open spots. Sometimes, shit happens and people can be in a bit more of a rush where they don't want to drive in a slower lane when there is an open lane that can and should be used. For those drivers, why should you care and get angry about it? Why would you swerve over a bit making you the illegal driver making it personal?
An example for one of my drives is a highway where 2 lanes merge into 1 at highway speed... before it merges with another highway. Pretty much all the time the left lane has more cars because people know that's the lane that continues on technically... but the 2 lanes pretty much both move over making it a true merge. The right lane always has cars driving until the 2 lanes merge, but it's usually less crowded so those cars can go a bit faster, even though it's under the speed limit. I have seen cars slow down to 35-40 mph in the left lane when there is a half mile wide open in the right lane. If I see a totally open lane where I can and should legally drive, why shouldn't I use it? Traffic can move easier and stay the speed limit if people used those 2 lanes how it's meant to... keep up speed in both lanes and merge every other lane/car. But no... some cars in the left lane take it personal and feel since they slowed down and waited in the left lane that people coming up on the right lane should not get ahead of them. Even though there is wide open lane for another 1/4 mile. I have seen people in the left speed up like you said Dave just to cut off the merging traffic. That merging car did nothing wrong, was not speeding and was not cutting off people... they were simply using the lane that was there and merging over as it was designed. I have also seen people in the left swerve over to cut off people coming down the right side even though there is a lot of road remaining in the right lane, legally and safe. Who is the problem driver there? The person driving legally and under the speed limit, or the car swerving?
If someone can't handle cars getting in front of you, then use the open lane. If you are only talking about the jackass drivers that fly down the merging lane even after the line has moved over, or cutting over and having to slam the brakes on... then I agree with you.
