That's one persistent cop who wasn't giving up. The trouble is chasing kids is they have no fear, I know what i was like on my bike as a teenager, you just don't have any concept of danger. He was never going to lose the cop on the open road, think he might have got away round the alleyways if he hadn't of clipped that concrete block at the end. The cops smug laugh at the end.
It shows how impressed you both were with both riders skillset, as neither of you mention, what a great ass the pillion has.
