AI Helicopter attached escort creation

[chromium]

Hi all,

 

I'm looking for a way to create an attached escort for vehicle column made by a couple of ai helos that should orbit in a racetrack similar circuit which is moving accordingly to the vehicles ruote.

 

My idea to simplify at most the task could be to dynamically create waypoints using first and last vehicle position as reference (ie using mist.gotorandompoint beach time), but i've no idea a out show to tell the helo to change the waypoint everytime.

 

Has somebody tried something similar? Thanks in advance

:)
