Also should fuel trucks and fire trucks be taxiing on the main taxiways? A few get in my way when I'm taxing around. Shouldn't they just be using the regular roads?
I had this issue as well. I was taxing in just after landing, and a firetruck blocked my path. Thank goodness I turned off crash detection (specifically for situations like this), otherwise a 5 hour flight would have ended in frustration. Great scenery though!
