In NY you can almost always catch a car if you want to (enough lights and traffic in most cases). I get the frustrated urge to hit a car sometimes, but I have never done it. I have decided to race a car sometimes after being cut off or honked at. Unless they get lucky with lights and a clear road, I can beat most cars for quite a while. I bet most of them ignore me or don't get the point, but it makes me feel like I win and it doesn't lead to violence or lawsuit.
