You can tell how well the economy is doing by how often people leave notes after hitting a car. I live in Los Angeles and almost no one leaves a note. It's too cut throat out here. We're paying $1800 for studio apartments. Rich people drive old Hondas in certain neighborhoods just so they don't have to worry about the inevitable scratches and dents. There's a tip for you if you ever get money. Buy a Maserati and a Mazda. Drive the Maserati in Beverly Hills and the Mazda in Highland Park.
I've been guilty of this. You hit a parked car so you get out, assess the damage, and then see that people are looking at you. You either have to leave a note, jet, or fake a note. I'll usually go with faking a note, unless my car is still running.
