Being from the area where the accident occured, it appears that debris from the Passat was found further up the road from where the impact was. This would indicate that the Corolla 'pushed' the passat back the direction in which it came from after the impact. Now, assuming that the Corolla driver was doing a safe speed of around 70 - 80 km/h, and the weight of the passat with the extra passengers, the passat could not have been doing any great speed for that to happen. The laws of physics don't allow it. Although this distance is small it's still a distance. Both cars ended up in a ditch a few metres from where the impact was. This would imply that the combined force of the impact cancelled out the momentum of each car and causing them to mave laterally into the ditch. This also suggests that the passat was not moving fast. Judging by the state of the cars, it appears that the Passat was side-on to the corolla, perhaps skidding sideways.
