It's a shame that old long tail could not have been a little more to one side, he looks to have hit the inside of that car between the seats. A touch more to the left and there would be one idiot less driving at 140 mph, even if it is on the German autobahn's. As for the other prat, I do hope there was enough disturbance inside the car to ruin his day big time. Absolute madness, whatever speed was he/she doing.
You don't get many children on German Autobahns!
Having spent some considerable time over there, went to the Higher Education Centre in Mulheim, same place as the car registration, saw less high speed accidents over there than in UK.
When there is an accident it is normally pretty horrendous, due to speed, but all the traffic is travelling at speed on the Autobahns anyway.
