An collision on San Francisco streets turned into an apparent road rage incident Monday night, when an errant driver fled the scene of the crash then shot at a fellow motorist.

It all began at around 8 p.m. Monday, at the intersection of Hanover And Guttenberg Streets. That's when, police say, the male driver of a sedan sideswiped a car driven by a 27-year-old man.

As opposed to stopping and working things out, police say that the sideswiper "attempted to flee" the scene, but his sideswipee followed him.

Clearly eager to escape, a passenger in the sideswiping car then "leaned out of the window and shot at" the pursuing driver.

Neither the collision victim nor his car were struck, but the gunplay was enough to end the chase, according to the San Francisco Police Department.

As of Tuesday morning, the delinquent driver and his gun-wielding passenger remain at large, police say, and no arrests have been made in this case.
