Is the right lane the new passing lane?

I didn't expect to see that flair, but it's not JUST Greenvillians

Hey y'all,

I never had thought about this until a trip to Texas last spring. There're signs saying "Left lane for passing only. " Needless to say, I soon learned that the inverse was true there. Back here over the last few months I've begun to think the same. Should we just ask the state legislatures to make the right lane only for passing? SMDH #stayouttatheleftlane
