A new YouTube video appears to show a female motorcyclist in Russia throwing trash back into the car windows of litterbugs.
The motorcyclist zooms off before the drivers can react.
One driver gets a face full of cigarette butts, while another gets back a fast food bag containing either a milkshake or coffee.
