*checking video out again*.... oh... are you referring to the first spin where the cop bumps into his rear? If you are then, it's a tactical move practiced by traffic officers across the globe. In order to spin the car they're chasing down, they target an area just behind the rear wheel of the vehicle at its rear bumper. It was the momentum that did the rest. The driver of the stolen vehicle just spun it back.

Hope that answers your question.
