If it is a motorcycle cop, there is no way. They only write tickets as 95% of their job and there is just nothing you say that is going to get out out of it. It's nothing personal, they are just in the business of enforcing traffic laws and writing tickets.
The patrol officer who writes tickets in between 911 calls, are more likely to give warnings. Just keep your hands on the steering wheel, announce you are reaching for your insurance, registration, wallet before you do it, smile, and if you were actually commiting the violation they stopped you for, own up to it with a " Yeah, when I saw your lights, I looked down and was surprised to see how fast I was going, I am normally pretty good about keeping it below the speed limit" We are so geared to hear the typical denials and muttering under the breath that the rare person taking responsibility for their actions might catch us off guard and warrant a warning.
Just know that your admission, if it fails, will cost you the court case if you are one of those who fight every ticket regardless of whether you were guilty or not. Cops will write the qoutes down on the backs of their copies for future reference.
