Lol, not really. Pretty much comes down to what the cops feeling like on that particular day at that time. I mean everything else is common sense. Don't have rap or metal cranked when he walks up to you, don't start off the conversation with "Why the f#$K did you pull me over pig nuts?!" I wasn't doin nuttin!", don't beg for forgiveness or offer bribes, especially don't say "I'll do anything if you let me go!" if you live down south and last but not least, don't DO anything that would get you pulled over while there's a cop around.

Common sense stuff aside it's a crap shoot. They usually have your record up on their computer before they come up to your car, and have pretty much already decided the outcome before you say a word, so just take it in stride and don't incriminate yourself.

The real ticket negotiations come after, bypass the defender, judge and everyone else and go talk to the local prosector before your court day and work something out, can usually get it knocked down to nothing or just a fine without ever having to see a day in court. They really just want your money, as long as your not perceived as a danger to the community they'll usually let is go with a fine on some lesser deal that won't go on your record.
