Npc's drive cars??

Can You get Npc’s to drive cars? Is there a mod that allows an npc to drive a car, or does it need to be scripted in with the map?

Also how does the passenger mod work?

Nope no mod.

How does the passenger mod work at the link?

Its for multiplayer, so players could enter your vehicle to drive along with you without all those problems of setting up the chair.

The Passegner mod doesn’t work for Ai does it? Just other players on multiplayer

I wouldn’t think that they would be able to use vehicles.
