I had a car that was pulled over dozens of times so the cops could take pics with it. Most of the time it was cool. Two times pissed me off: one time a cop had just pulled me over on the highway for a pic, okay cool, I pull back onto the highway and went maybe a mile before I was pulled over a second time by his buddy.

Other time I was just rolling into LA for a comic con, it was 3am and I'd been driving for about 14 hours. I was minutes from my hotel and of course here come the cops. I had to make a big detour to find somewhere safe to stop. The next day someone said "Oh, I think my buddy stopped you last night!" so I had him call his cop friend and was able to safely cuss him out from a distance :)

On the other hand I had one awesome experience with the cops in Oxnard when we put my car on the train tracks and accidentally set off the barriers and caused an enormous tailback in each direction at the railroad crossing. I thought the cops would be mad, but they were hilarious and promised to figure out the traffic snafu for us.

Then an hour later when I was driving the car down the tracks again another cop walked up on me all mad and told me he was writing me a ticket for driving on the tracks, but when I read the ticket he'd written it out to Marty McFly and had a great laugh about it. Here's a pic of him booking Marty haha
