After a couple of friends had recent run ins with a cop, I don't believe they have quotas.  
One was street racing out in the boonies when a cop showed up.  He said, "I used to have a souped up Mustang and do the same thing all the time.  Why don't ya'll go to someplace a little further out where you don't have to turn around in people's driveways?  We've been getting complaints."  He then sent about 10 of them on their merry ways.
Second was a different guy going 120 in a 45.  Cop pulled him over and said, "Boy, I don't know what to do with you.  I should take you to jail.  But, I don't know why I'm gunna do this, but I'll let you go.  Just slow down."
Of course, the one time I've been pulled over <knock on wood>, I had to get a ticket.  I turned the dome light on, radio off, both hands on the wheel.  Cop asked for registration, I told him it was in the glove box before moving.  He asked me how fast I was going, I said about 70.  He said close, 72 (in a 55).  He asked why I was going so fast, I said "No excuse sir."  Welp, here's your ticket, slow it down a little.
