This is what we call "instant karma". Bill Walsh, a bicyclist, who seems to have suffered from drivers making illegal U-turns on Pennsylvania Avenue in Washington, D.C., as evidenced by the head-cam videos (see below) featured on his YouTube channel, finally saw justice served.
While riding on the bike lane, Walsh was confronted by yet another driver looking to make a quick U-turn. Infuriated by the move, he yells "Illegal, illegal!" to the driver of the Toyota Prius taxicab, who doesn't really seem to care.
