Answer 3

If you are looking for "expert scientific testimony" to support a court case, you have come to the wrong place.

Answer 4

Not at all, my dad was involved in the accident. And no one was hurt, insurance info was exchanged and parties went home uncited. I'm just fascinated by the forces involved and very curious as to the physics causing the spinning effect . My dad says the Mercedes weighs as much as the van or even more. Thanks anyways.
