I have to say that the seat and headrest in the Jag undoubtedly saved me from whiplash. It is estimated that the girl went into and under the back of the Jag at about 70 km/h. You do hear a moment of tyre/brake squeal on the dash cam footage just a moment before the impact. The Polo was destroyed and it's engine exploded with oil all over the place. Unfortunately jnr has suffered some lower back pain, hopefully nothing serious, she was sitting in the back seat.
Worth noting that the car automatically called Jaguar Assistance and they were on a hands free call asking if an ambulance was needed even before I could get my breath back.
