The thing is, if your a fast driver, if you've been doing this long enough, you've pushed people out of the way. Don't come on internet forums lying through your teeth saying that you just wait behind slower drivers just to be a nice guy. You would never be a fast driver if you did.
Just say it like it is in the world of any racing sport, truthfully.
If the slower guy dosen't get out of the way on his own, the faster guy will get around you, one way or the other, the actions the slower guy takes to get out of his way, will determine how the faster guy gets by him. One thing is for certain, the slower guy is going to learn alot more about racing in that instant than the faster guy will.
