We won't blame you if, after watching this scene recorded by a dashboard mounted camera, you're wondering what the bleep just happened here. We can try to describe the incident, but don't expect any solid answers.
What we see is an old Lada hatchback with Russian license plates coming to a stop at a red light next to an even older bus. Then, all of a sudden, a man exits the passenger model and goes around to the driver's side of the bus.
What went on there remains a mystery, but the young man returns to his car, then gets out again, and runs away, while someone from the bus holding a camera takes pictures of the Lada's front license plate.
Meanwhile, the man returns to his car and drives into the other man knocking him down!
