I have found shutting the engine off, makes them at ease....I started driving at 22, I am 42 now I have been pulled over many many times in that 20 years, only once did I run into a salamander, even the ones that had to arrest me were good folks, just doing there job.......then again I never freaked out or went off on any of them......
the best one was me driving my challenger.....
officer-"took me long enough to catch up with you"
me- "thats cuz I slowed down"
officer- "license and registration"
me-"I got some good and some bad news......bad news is...... my license is suspended.........good news is....I got bail money..."
Texas state trooper clocked me at 101 in Ft Worth.....let me go no ticket.......his first words to me were...."Boy....I seen some stupid watermelon in my life....but you done take the cake....." he was actually a very cool guy.
another good one...I stopped the challenger in front of speed limit sign..do my normal and shut the engine off right away......the cops says to me...as you can see....(pointing to the sign) the speed limit is 35 not 75........
treat them with respect they will most likely give it right back.
