I know what you mean about the blue flag thing, on a server one day, i was in an xfg and had just came out of a chicane, quite slowly as it was my first time on that track. I am guessing that the blue flag message comes up when a faster car gets a certian amount of metres away from you. So, i saw the blue flag message, went to look in the mirror so i could see which way i needed to move to let the other car pass.I looked in the mirror, only to be rammed off the track by a very very fast xrg before i had the chance to steer fully out of the way, i was steering towards the grass as best and as quick as i could. I was then given a tirade of abuse such as wtf noob, blue flag means move you pr!ck. i was less than impressed, but i was cheered up again when i saw him buried in the gravel on the next lap, i even gave a as i passed. Haha!
