I'd highly doubt that a ticket given for impeding traffic flow for driving at or above the speed limit in the left hand lane would actually hold up in court. That isn't the intent of the law.
And evidence of this can be seen here:

An Ohio driver was ticketed and convicted for impeding traffic, but an appellate court overturned the original decision.
