Somewhat unnerving

Coming home tonight, I approached and had to slowly drive through the aftermath of a traffic accident: fire engine, paramedic ambulance, two police cars, tow truck, shattered glass on the ground. Didn't have time to try to make out just what had happened, but it was rather unnerving because this was all only a block-and-a-half from my condo; I don't recall ever personally seeing or otherwise being aware of a traffic accident that serious that close to home.
