Coming home from work this afternoon, in moderately heavy traffic in the third lane of a divided 8-lane highway, speed limit 65. I was going along with the rest of the cars, which were going 70+, some faster, some slower. Cars were passing me on either side, and as I came around a turn, there was an unmarked police car on the left shoulder. Red Buick passed me in far left lane, and I remember thinking, "Oh, uh, his goose is cooked". Well, the cop stopped me! He asked me if I knew the speed limit ("Yes"). He wanted to know where I was going and where I was coming from. He stated he had radared me at 79 miles per hour. I protested that I was doing substantially the same speed as most of the other cars, and that cars were passing me on both sides as I went past his car. I have a perfect driving record, 54-year old male. He wrote me "79+ / 65 / 70" and said he was "giving me a break" by writing me 5 over. In Michigan, what will this mean to (a) points, (b) insurance? Is it worth fighting? I believe his radar picked up the faster cars, but I was driving a 2003 Cobra. Why is he so interested in where I'm coming from and where I'm going? Is it legally any of his business? By the way, this is third ticket since 1963; other 2
