Well 5mph isn't really speeding; as far I know they set the speed limits 5mph lower than they really are (e.g: 55mph means 60mph).
But trust me, the imaginary police are very much not imaginary. I got a couple speeding tickets before I decided I wasn't going to deal with the courts ever again. Now, I do the speed limit. I see cops everywhere on the highways in my state and they definitely will pull you over going 10-ish over. Until recently, anything over 80mph (even if the highway was posted 70mph) was reckless driving (now It's 85 I think)
