Oh I put down $50 (AU) on them taking another car. Standing round a station, or a pier....nooo. I cant see that happening.
They have to steal a particular kind of car, too. It's not as if they can just hive off any old jalopy, they have to put thought into it, and cars are, in general hard to steal with the electronic starters etc.. A particular set of circumstances has to be availiable and the smaller their area of where they can steal a vehicle , the less chance they have of that particular kind and availability to present itself.
The law of diminishing returns, made manifest. You steal a car to go off into the wilderness, then you are reliant on stealing other cars to continue the journey, yet, you have placed yourself where there are fewer and fewer cars available to steal.
