I just started playing around with traking objects in Lago's FSSE for ACOF. This is just too cool. I now have buses going from terminal to the parking lots and security vehicles patrolling the airplane parking areas. Don't want anyone breaking in and stealing our expensive avionics equipment do we. 

I also put in a couple "Follow Me" cars. No way to get the AI traffic to follow them at the moment but just having them moving around is neat as heck.
