Bingo. I've been wrongly accused of charges, I've had mistaken identity against me ending in a full felony stop pulled over by 12-14+ cars with guns drawn, been detained multiple times while they're trying to figure out something to give me when I technically didn't break any laws, had an officer slam my door on me after lying about my tag light being out, been pulled over and accused of driving under the influence because I was dodging pot holes, popped for racing and let go, searched an infinite amount of times, I've stood on the side of the road yelling face to face one on one with an officer like a coach vs. umpire after he acted as if religious ethics overrode state code during a funeral procession...I simply said lets continue this discussion when his supervisor arrives and see how the conversation ends. He immediately sent me on my way.
My demeanor and calmness in emergency situations has also allowed dispatch to put me directly through to officers after calling in a driver for wreckless driving possibly under the influence once and a hit and run another time. Stating the speed and exact location until they arrived both times. Nothing better than telling an officer I'm approaching 75 mph in a 45 while following a van that just ran a car off the road and he say, "It's alright, just keep informing of it's location." I'm sure it helped that they had multiple calls and I was the only person traveling the same direction as the suspect.
I've been pulled over countless times for countless reasons but how they treat you normally depends on your attitude when they walk up and your driving record after they run it. If it's a congested or higher speed road it also tends to help being conscious of where and how you pull over enabling everyone to be safely off the road. If they don't bring it up make it a point that you consciously made the effort.
