And you might not like the answer:
It all depends on what everyone else is doing. If more than 50% are changing lanes then you don't win if you change lanes but you do if you're in the minority. This mirrors many of the results in game theory where a selfish strategy works well, but only if it is the minority strategy. Given most drivers stick in a lane then swapping is probably a good choice — unless this news gets out."
