I guess directed to Besser:
On the actions of the cops. Knowing several police officers, I believe they are concerned for your life and what your wife and child would have to bear should you get hurt or die in an accident. So you re putting yourself and your family at risk in a sense. And its common knowledge that most car accidents happen close to home or on short drives.
So why it might be annoying, they probably really cared about you. They also probably have seen the aftermath of not wearing a seatbelt.
Also, they are cops, so they might be bored and were having some fun.
