Haha, I believe everyone speeds, and a lot of cops don't care generally as long as it's not excessive. But you will run into that one cop who is having a bad day or is on a power trip and will pull you over for seemingly nothing. Definitely talk to your guy and get on the same page before trying this. And please don't abuse it, follow the laws, and follow orders of the police stopping you. Even if you get a ticket, it's better than getting arrested, or even killed, and if you truly haven't broken any laws you can usually fight it in court and sometimes win because some officers won't bother to show up in court which will automatically get it thrown out.
