Overtaking on the right is a no ... no in Germany and most of the other European countries. The yellow Bimmer was definitely the main culprit (besides speed).
The driver in the blue car pushing the yellow out (near end of first video clip) did not hep much either. I wonder if the kid in the photo below was the driver of the car in this photo ~grin~ .
Speed and reckless driving was mainly the cause of this ... hope everyone escaped injury.
