They like to build up technical charges. A neighbor of my brothers was at a light
in his souped up, chopped down pickup. He was stopped at an intersection with
a cop coming to his right, and me at his left. He was looking over at me and
waving and didn't see the cop. Well, his light turned green and he squealed from the light making a left past me. The light show followed him for half a block.
The cop got him for like 4 different charges, but my favorite was for Inattentive Driving. He should have seen the cop at the intersection :-)
