I have a friend who is a retired IRSU member. He says his stops were about education, and to chat with the person about their choices. He didn't reach for the ticket book unless the person was rude or had engaged in very dangerous driving. Some things get automatic tickets like no seatbelt, texting, excessive speed, etc.
Maybe he's the exception to the rule but every cop friend of mine from various local depts call them zealots and tax collectors. I dare you to do an FOI on them to ask if they run any data to show how their work improves safety in known incident black spots. I also dare you to FOI and ask for the % of tickets written broken down by speed, tailgating, failure to signal, distracted etc.
I have a lot of respect for police and the hard unforgiving work they do. Not so with IRSU zealots picking low hanging fruit.
