I had a nearly full 20oz. plastic bottle of orange soda thrown at me a long time ago (riding on the side of the road in a residential area, plenty of space for cars to pass). I think the bottle passed under my frame between the wheels. The car was going too fast for me to get a plate # and when they saw me trying to catch up sped up even more and ran a stop sign. I saw a police officer running radar a couple miles up the road and let him know what had happened and where. He said he'd go check the neighborhood and immediately headed that direction...he seemed to genuinely want to go catch them assaulting some other road user or speeding through another stop sign. FWIW if it's a glass bottle that counts as assault with a deadly weapon (a felony) and the police should definitely take that seriously.
