A few years ago when Essex Traffic Division were still using bikes extensively I had a day out at their driving school in Chelmsford where one of the instructors showed us photo's of the damage done to a Ford Fiesta that pulled out on one of their officers mounted on a Honda Pan-European. The impact speed was estimated to be approx 40mph; the rider had "flown" over the top of the car, fortunately sustaining only minor injuries. The front of the Pan was definitely somewhat squashed, but the shocking part was that the Fiesta was almost cut in two. I don't remember the injuries sustained by the driver or whether they survived.
