[Feature request] driver and passengers in limousines.

[Fifteensencher]

What should happen

In traffic, the Stretch limousine will always have a driver and one or two passengers in the back seat, with no front passenger. This is probably specified somewhere in the sco files. I suggest doing the same for Cognoscenti, Super Diamond (TBOGT), and Stretch E (TBOGT).
