Poor soul never had a chance, not even in a car as well built as the XF. Even if he/she stayed buckled in and hit nose-first, the impact would have been like hitting a granite-face mountain at 80+ mph. Not much crumple zone for that. The car looked like it landed flat on its underside and rolled, much worse for the human body, especially the spine and skull. Just hope they died painlessly.
