This is just my opinion but I don't agree with you. If you and a friend were walking side by side in a narrow hallway slowly with a crowd of people behind you would you continue to block those people or would one of you get ahead of the other in a single file fashion so there was room for others to get buy. It is no different on the roads, if someone is doing the same speed as the people in the right lane it would not hurt them to move over to let faster traffic pass. I think it is rude for people to impede the flow of traffic just because they can. The law also says I can play my music at a high level until 10pm but I don't because I know my neighbor does shift work and might be sleeping. This is no different, it doesn't hurt me to listen to my music at a reasonable level to accommodate others just like it wouldn't hurt the ones doing the speed limit in the left lane to pull into the right lane to let traffic by.
BAN NEIGHBORS!!!
