Here is quite a fun video that I found of some guys using a video feed from a Hexacopter to drive a car 
in 3rd person! I dont suggest anyone tries this on real road though!
I have not had a proper look but it looks like they used a DJI drone, would of been even better if they used an APM/Pixhawk powered hexacopter platform and then they could of use the follow me function to keep a constant distance and altitude from the car to make things abit easier.
