Illegal parked car opened driver side door suddenly and collided
I was driving along a street (about 20 mile/h)and the way was clear utill I passed by a parked car. The driver opened the driver side door suddenly and collided. He told me he was opening the door to get out. But after the police told him, it's his responsibility to watch the traffic before opening the door. He changed hiis words that he got into his car and about to close the door. The statesment from both side of us were recorded in the police report. The collision mark was on the edge of his door and my right side of signal light and fender. (His door was squueezed and there were long scratch on the right two doors of my car too). I also found the car was parked beside a fire hydrant and 11/2 feet away from the curb. How do I win the case with the evidence? He has full coverage insuance, but I only have liability.New York.
