Hill hopping scene repeated

The cars jumping the hills is repeated four times, meaning it's the same stunt shown from different angles. First, through the windshield of the hitmen's Dodge Charger; then interior of the Mustang over the shoulder of Bullitt; followed by a close exterior stationary shot of the cars making one dramatic leap; finally from the bottom of the hill showing both cars jumping all the hills coming towards the camera and making the left turn at the bottom.

Note that the ubiquitous VW is passed by the Charger in the same place in every one of the shots: just cresting the lowest hill, and just as the chase cars turn left, the blue Caddy that stops short in the intersection can be seen in two different angles.
