Just so you know, radar needs a steady, clear target to "lock" onto thats why when traveling on the highway it is good to stay next to larger objects. The doppler radar has a hard time picking the smaller object up and you can get lost in the "Shadow" of the bigger vehicle. However when your taged in the middle of nowhere, a honest approach always works. Like, "Yes sir I know I was speeding, Why? Because I didnt think you were around of course"
Laser on the other hand is target specific. Look through the cross hairs, press the trigger and whamo. You can be taged from about 5-600 feet away. In other words by the time you see them, they have you. Also difficult to fight in court. Laser does not disperse like radar over a distance.
I guess just stay about 15 over and you should be o-kay. Now as for a sense of humor, If he was smiling, walking towards him with a ticket book in one hand, and a pair of cuffs in the other....now that is a sense of humor.
