Depends on the multi-lane speedway. Not all multi-lane speedways are like the six to twelve lane affairs found in and around cities. Some have only two lanes going in each direction, and on such roads, which lane people use for what purpose makes a much bigger difference, especially in hilly or mountainous areas. And nobody does all of their driving on multi-lane speedways, so being mindful of the possibility of such a law is still a good idea.
