It’s not a viable defense if you get a ticket for speeding but in practice the speed limit is really the prevailing speed of traffic plus X mph, where X adjusted for the state. I.e. in my experience Texas is more strict about the speed limit even on their desolate highways, LA is about 10 mph faster than San Francisco, in Seattle it depends on the weather, you’ll never hit the speed limit in New York anyway, and in Florida you just say the gator ate the officer who pulled you over.
No they don’t, you’ve misinterpreted what was written. “Not impeding traffic” is not codified as “exceed the speed limit if everyone else is, or get a ticket”.
Or perhaps you have a documented counter-example.
"a person who knows, or should reasonably know, that another vehicle is overtaking from the rear the vehicle that the person is operating may not continue to operate the vehicle in the left most lane"
With of course some reasonable exceptions.

That's a rule just about everywhere, but that's not what's being discussed. I'm in the right lane doing the speed limit, and OP claims that's "technically" illegal due to contradictory laws. (Where there is no real contradiction, because the Chesterton's Fence is that we don't want Farmer Jones driving his tractor to his fields down I-75 through Atlanta.)
