It's also tremendously inconvenient. You might be a few minutes late for your next thing if you wait for the police. Doing the right thing is only reasonable if it costs nothing.

I know it's sarcasm, just wanted to add that I've never seen police respond in under 30 minutes. Even when the police department is literally 20 minutes WALKING distance.
Edit: That was in a small town though, I guess it's different in the city where I constantly hear sirens.
