According to ABC7NY:
"The video was shot by a Target parking lot surveillance camera. You can watch as a pick up truck bumps the ball, jarring it loose, the ball starts to roll into traffic, and smash! Right into a moving car.
"All of sudden I hear this crash and a really loud noise," Eileen Grady said. She thought she ran something over, but it was the 2-ton bollard bouncing of her driver's side door.
It ricochets and keeps on rolling. A brave man jumps out of his car to stop the ball, followed by his dog.
A red dent in her Nissan Rogue was left behind. Grady says the impact also shot a nail out of the ball into her rear tire."
