I have had this happen, and I immediately boot them off the wheel. I also say that under no circumstances are they to take the wheel without asking first. I honestly dont mind letting someone else drive once in a while, but they had better ask first... If they try it again, I boot them, full cargo or not, we land and I tell them why they are getting booted from my friends list. Has only actually gotten that far once. But then again, I am usually very careful about who I make my friends *shrugs*.
