I have seen this as well, I think it has something to do with the FS2004 AI engine. I would recommend disabling crashes. There's not much you can do, but I believe that once you have contacted ATC in FS, they "recognize" your aircraft and stay back. Either that, or the ATC makes them hold short. Hopefully Microsoft can fix their AI problems in the next FS, but hey, bad AI is better than no AI!
