There's no telling what I would do. Most likely stop the car and get out.
Few years back I was driving my mustang through a neighborhood and some kid was standing by the road throwing rocks at me when I drove by. I slammed on brakes and threw it in reverse faster then I ever have before. Pulled up their driveway, kid took off running and I go knock on the door and tell his parents what he was doing. He didn't hit my car but The kid had to come apologize then his dad made him go out in the woods and grab the stick he was going to his ass whooped with.
Never did see the kid throw any more rocks
