Video: 'Ghost' car appears out of nowhere on busy Russian intersection

OK, y'all have to watch this video and explain where the car in front of the BMW appeared from. There has to be a reasonable explanation to this. Footage taken from the dash cam of a vehicle behind this BMW in the pic shows a car suddenly appearing in front of the BMW after it turned left at a busy intersection in Russia...nearly causing an accident. Watch the video after the cut and tell us what you think happened...
