No. Even if there is a mathematical theory that predicts there is, human (and particularly automobilistic) perversity means that nothing you do is likely to help in practice. In fact, it is a well-documented fact that too many people changing lanes in the hope of getting one up on their "fellow" drivers do, in fact, cause the jam to worsen.

Supposing this is true; that numerous lane changers causes a jam to worsen, then the rational driver will at first
conclude that if everyone stays in their lane, they will all be better off, including him.
But then a lone lane-changer in a jam full of non-lane changers may benefit more than the average non-lane changer does.
This is similar to the game theory conclusion that in some situations, solo defectors can benefit from a situation that they would not benefit from if everyone defected.
As an RHP example, the solo machine user in a tournament may benefit (may win the tournament) but if everyone used one, he wouldn't. Similarly, the solo sandbagger (ie, who purposely lost games to lower his score) who entered a banded tournament would benefit, but if everyone in the tournament had sandbagged, he wouldn't benefit.
But back to the lane changer: The solo lane changer still needs some lane-changing rules.
