@Tuiridh = this might be solves in v1.2 because you can't get into a vehicle if there is another person near it. This stops the "flying in thin air" issue. It wasn't really the ideal fix but it was the only one that worked - I tried about three things. But in a way it means no one can take a vehicle if you're next to it refuelling. On the other hand they could stand there to annoy you, which I expect, but then you'd shoot them? @G - survival. It's the only goal of the entire game. It's all designed around that.
