Well, the jib arm with Libra III gyro head, would have been running alongside a road and filming the car driving parallel to it.
That'd be my guess.
They use those arms on camera cars/bikes all the time for car spots.
You can rotate the head on all 3 axis too.
To get those 'dutched' angle driving shots.
Used a similar set up on an Audi spot a few years ago.
