He backs his car into vehicle and then shoots at vic driver

A Brooklyn motorist stopped at a red light backed into the vehicle behind him — and then fired a gun when the struck driver tried to exchange information with him, shocking video released Tuesday shows.

The 53-year-old victim was stopped at a light on Palmetto St. at Bushwick Ave. when the white Honda sedan in front of him suddenly reversed and hit his car at about 5 p.m. on April 9, cops said.

When the victim got out of his vehicle to exchange information, the driver who struck him leaped out of his Honda with a silver pistol in hand, police said.

Cell phone video from a witness released by police shows the gunman shouting at the victim as he circles him with the gun in his hand.

He fired a round at the victim but missed, police said.

The gunman hopped back in his Honda and sped off north on Bushwick Ave. He has not been caught.
