There are no red, yellow, green, black, black-and-orange, black-and-white or red-and-yellow flags in the game, so why would there be blue flags? And more importantly, how would the implementation of blue flags work? You could wave a flag at a backmarker as much as you like, but if they don't want to move over, they won't. And there's not much you'll be able to do to stop it.
Stop trying to ignore the serious flaws of this game with poor workarounds.
The entire point of B-Spec is to build your driver up. They start out green and you're meant to nurture them over the course ofa carerr. The more experience they get, the better they'll be.In b-spec thats not as easy
Stop trying to present non-solutions as valid alternatives. Because when you think about it, passing a backmarker under your own power is much easier and much more realistic and much more effective than showing a player a blue flag and expecting them to move over. Unless you want to give them a five-second speed-limiter penalty like the one in rally mode in GT4 - but that would only deny them the right to race for position themselves (ie, you come up to two backmarkers fighting it out; one moves over to let you through, but the other does not ... a penalty is only going to hurt them).
