I have a first hand example - with Porsche content, no less. Last August I flew into Beijing in a downpour. The family met me at the airport at about 10 pm and we hopped into a taxi to negotiate the trip home. Traffic was a nightmare and eventually we saw red flashing lights marking the inevitable accident. We came upon a small domestic car that had rear-ended another small car, pushing it into a Porsche Cayenne.

The first car was smashed, the driver hit the windshield and there was a huge star where he hit. He was sitting by the side of the road, obviously hurting but trying to look not hurt. The middle car was destroyed. The body was pushed back to both axles. The Cayenne was almost undamaged. It was hit on the left corner of the rear bumper and it looked as though someone had backed into it in a parking lot accident.

The star on the windshield was pretty bad but the driver's head didn't go all the way through. That, combined with the speed traffic was traveling before the accident suggested to me that the first impact was about 30 MPH.
