what do cops look for?

Who knows with cops, but they do watch your movements and hands very closely when they approach the car. Maybe the guy was training in a new cop and wanted to go through the basics? It might have been cause they seen you messing around with the mirror and not watching the road. Funny he didn't talk to you more or be a little more polite atleast. Doesn't sound like you did anything wrong, maybe they were just bored? Checking for stolen vehicles? Who knows really...glad to hear you didn't get a ticket :glasses7:
