I had the opportunity to be inside of a police car only one time. It was 4th of July, sometime around 2001 or 2002. I had just merged onto a two lane highway where the speed limit was 60. There was a new silver Impala (civilian) who I noticed was coming up very fast on my rear view mirror. The driver was obviously miffed because he thought I had pulled out in front of him, and decided to show me how fast he could go to get around me.
Well, it wasn't going to happen, as I was in my 240z that had been hopped up with all sorts of go fast goodies, and mostly stripped of everything inside (read, weighed nothing). I watched as the Impala kept getting smaller and smaller in my rear view mirror, and only had time to train my eyes to the car in the opposing lane flip on his lights, and proceed to do the fastest direction change I have seen yet. He flew past the silver Impala, and pulled up next to me on the curb (I knew I had been had, and didn't want to be in even worse trouble).
I had just turned 20, skinny, and obviously not any sort of physical threat. The state trooper had me sit in the front seat of his cruiser while he ran my information to see if my I had any warrants or anything of the like. He clocked me going over 110MPH. I explained to him that I was trying to outrun the Impala he had passed before pulling me over. After we had a long conversation about speeding, about his riot shotgun he had tucked in the holster on the transmission tunnel, and my Datsun, he let me go with a warning.
I realize now he could have written me a much-deserved ticket that would have resulted in the possibility of me losing my license, and/or possible jail time. Being that I was young and stupid, the state trooper made quite the impression on me that I still hold today.
