If I get a blue flag, I wait until there is a safe, straight stretch of track and then I ease the throttle to halfway, and move over and in a predictable fashion. When I ran the LeMans League, it worked perfectly when I enforced that rule concerning blue flags.
Also, save the "blue flag" b****ing" to when the race is done. You and the other person are not the only ones who see this message, and I am willing to bet it royally screws up other peoples concentration, potentially ruining their race.
And I have said this before, people who bind blue flag messages either do not know how to drive in real life, or are quite ignorant. And I have also noticed, are under the age of 20. Not EVERYONE, but quite a few.
