Zyzmog's Fifth Law of Motion (proposed)

I've come up with a fifth Law of Motion. I'm still trying to find the right words for it. The formal declaration is something like this:

Zyzmog's Fifth Law of Motion
In any disagreement involving the previous Laws of Motion, the first appeal to authority is the victor.

That might be too stuffy for some people to understand. Here are two attempted rewrites:

Zyzmog's Fifth Law of Motion (reduced)
In a traffic altercation involving vehicular contact, aggressive drivers, texting, drunk driving or road rage, whoever calls the cops first is the winner.

Zyzmog's Fifth Law of Motion (final reduction)
(also known as Barela's Law of Forward Motion)
Whoever calls the cops first, wins.
