I've only had one bad experience with a traffic stop. Usually my friendly, respectful, and easy going nature will win the day for me. I have found that starting off the conversation with an "it wasn't me" look on your face tends to help. Depending on the age of the officer involved, trying to dazzle them with footwork and baffle them with bullshit usually elicits a smile and a warning. Keep it light, keep your humor, keep it respectful and, above all, keep your pants on!
