I've had both good and bad experiences with cops. My last one was pretty good though.

Heading home from work on Hwy 92, I was doing about 55 in a 45. No biggie. Cops don't mind as long as you don't break 60. Either way, I was in the right hand lane with a car next to me that I was slowly passing when this Corolla pulls out in front of me. I could have done one of two things. Slam the brakes and plow into him, or slam the gas and go around him. I chose the latter. Easily doing 62 mph, the cop that was shooting traffic hits his lights and comes pulls me over. He asks me why I was going over the speed limit and tell him what happened. He said he saw the Corolla pull out in front of me, but didn't notice that it was that close. Understanding the predicament, he lets me go and tells me to be careful.
