If you drive the speed limit in the right hand lane, I commend you. Way too many Dallas area drivers drive slow in every other lane.  People need to realize that there is 1 traffic law that deals with how fast you drive (the speed limit law). Almost every other traffic law deals with traffic flow - Left lane passing only, Merge and Yield signs, Slow traffic keep right, even the signs telling you what exits are comig up, etc. The main problem today, is that drivers do not think. For example, an enforceable law (although never enforced) is the Slower Traffic keep right law. It does not say if you are going super slow that you should be in the far right lane (you should be, but that is not all that the sign/law means). It applies to every lane. The first time somebody passes you on the right - no matter what lane you are in, as a thinking driver, you should think: Gee, if they are passing me on the right, then I am going slower than them - maybe I should move over a lane to the right... (notice it has nothing to do with what speed you are going, because it is directed toward traffic flow - keeping traffic flow smoothly and spaced out). In the same manner, if the lane to the right of you is open, out of common courtesy, you should pull into it (until you need to pass a car - then pass, and pull back into it). Pulling into an open lane on to the right allows drivers in the lane to the left of you to pull into the lane you were in, so drivers in more of a hurry can pass them on the left. Even though you drive in the right hand lane, you still need to be thinking. For example, you are in the right lane, but you notice a vehicle in the lane to the left of you driving at pretty much the same speed that you are driving. You should automatically think 'if both of us are driving he same speed (even though you are in the right, and the other driver wrong) then 2 lanes are clogged up'. So you should speed up enough to get past him (on the right) and leave enough space between you and him for cars that come up behind you to pass him and then pull over in front of him, and pass you. Basic drive thinking. On a highway, if possible, you should NEVER be driving the same speed as the traffic in the lane to the right of you. Think about it - if you are wanting to drive the same speed as them, then doesn't it make sense to be in the same lane as them...? The most important thing that every driver should be thinking in my opion is this: What can I do (while driving) to make the drive easier, safer and smoother for every driver on the road? How can I improve the traffic flow?
