Every "driver's worst nightmare" scenario involves a child jumping out to chase a ball, or a truck careening into your path, or breaking down on a lonely road. But a clearly drug-addled man, riding the hood of your car, staring you in the face with dead eyes and clawing at your windshield is much worse.

The driver begs, pleads with the man to leave her alone, to take himself away, all while he continues to clutch on, making threatening gestures towards her. Each time he runs his finger along his throat, it gets worse.

Eventually, the police take him away. Hopefully they'll get him the help he so desperately needs. Probably not, though, because this is Russia.
