Scripting commands

useAISteeringComponent true/false

• enable or disable new ai driving across all vehicles driven locally on the machine.

vehicle forceFollowRoad true/false

• forces AI driver to stick to immediate road, as long as the path is near the road

vehicle setConvoySeparation 20

• sets distance between following vehicles, should be set for all vehicles in convoy with the same value.

vehicle setDriveOnPath [[1000,10,1000],[1100,10,1000]]

• sets a custom path for a vehicle, behaves like Move command but with ability to send path through list of points. Accepts array of arrays (3 or 4 elements). Either (x,y,z) or (x,y,z,wantedSpeed)
