Sooo ... 7 pages here and still nobody has a friggin clue why the LEO chastized this VC road HOG.
Well it's because he couldn't even share the 12 feet lane with a Motorcycle. This BS about excluding anything and everything from the entire lane width is absolute total nonsense. Ever see Hell's Angels ride single file ??? hahaha
Riding in the left track of the left turn lane is rather goofy also.

As for minimum speed limits for normaly capable vehicles, I am sure for highways it is generally 10 mph below the max.
