Been pulled over several times speeding in excess of 100mph. The key is to never admit guilt, talk to the officer as if you are confused why you got pulled over, but do it with a smile and be courtious. I've been lazored, paced, videod and I do not have one single ticket on my record. If you decide to travel over 100mph+ be aware you might be going to jail.
15mph over is considered wreckless/negligent and they can take you in if they choose to do so. Alot of them won't if you are not endangering other vehicles...in other words do it where there aren't cars around you have to dodge and the cops might be cool. I've had them let me go before after they pulled me over to comment on how nice my car is. Also between shifts is a great time to speed. Cops are headed back to base while others are in the meeting room getting their briefing. Find out by visting your local state patrol precinct or finding and making one a friend. Check out

Jeannie is awesome!
Goodluck!
