i haven't heard of this, all i get are shouts and people closely running up on me in their cars. If someone shot me with a dart, or pellet gun i'd just catch up at the red light and beat the living piss out of them (boxing background) and whoever else is in the car. That's why you carry a heavy lock, knife, and a pocket pistol for the different level of threats! I've never had to use any though, almost on some redneck old man who got out but quickly got back in his car haha
