I don’t think it’s stupid, but it’s wrong. The point isn’t that you had to follow him around checking where he went if you didn’t see him (now you are saying you saw where he went?).

The point is that you had to call the police. From there or from somewhere else. Or drive to police station. Or ask someone what to do if you don’t know. Even if he drove to the side or a parking lot he could still have physical injuries etc People are known to appear ok at first but injuries show up later. He could have a concussion or what not.

The point is that when you cause harm to people or their possessions driving around for months pretending nothing happened is wrong. Why do you still argue about it?

Yes there are other people who leave accident sites or crime scenes and don’t call police. They hope to avoid responsibility. Just because they do it, it doesn’t mean you should. Who cares if they are stupid. Just do the right thing next time
