In the USA, the left most lane is for passing. It's not "the fast lane", it's not for driving the speed limit or 5 above it. It's for passing other vehicles. It doesn't matter how fast you're going, it only matters if your passing other vehicles. If you are passing, then stay in it. If not, then get out of it. A driver can cruise in it if no one else is using it but it is rude af and basically sociopathic for someone to block the passing lane even if they are doing the speed limit. Cops enforce the speed limits, not sociopathic civilians.
A correctly running local government would enforce the passing lane.
