I see no reason why people travel in the left lane when there is nobody in front of them unless they are passing someone in the right lane.
The left lane is for passing.
I hate when I want to get past someone and they are clogging up the passing lane. You shouldn't pass on the right, and you shouldn't have to.
I guess the rules of the road should be made more clear to people. Maybe a refresher course is needed
