Police said the victim turned their car into the West Bradford Elementary School parking lot and looked back at the Audi to see the driver pointing a firearm.
Investigators said the Audi driver fired the gun, striking the rear windshield of the victim's car before driving away.
One resident, who did not want to be identified, told Action News he came upon the shooting shortly after it happened.
"We do feel that it's someone from this area. These are not well traveled roads," the man said. "Broad Run and Beacon Hill roads are not roads people from out of town would typically be on."
He also said the fact the suspect remains at large makes him nervous.
"This adds a little bit of fear into our daily lives. Sometimes I'd let my daughter walk over to this park by herself, but that's not happening right now," he said.
The driver of the Audi was described as a white man with dark hair and was possibly wearing dark-rimmed glasses.
