My proposition don't allow a 1 CHA caracter to lead 10 peoples, in order to drive 10 peoples you have to make a 5 CHA caracter + driver job lvl 3 (whose giving a +5 CHA bonus in cars), it allow team to create a new "driver" build and to see a real evolution. Evolution in stuff (having cars), evolution in build (new "driver" build remplacing "leader" build) evolution in gameplay (using a car, secure the car/keys etc etc).
