Exited Southfield Fwy going East on 8 mile. Noticed young male driver right on my bumper so I sped up to get away (he had both left and right lanes to go around) and when I got to bottom of 8 mile overpass a Sheriff was sitting in turn around lane and stopped me for speeding. I explained what happened and asked if he saw the other driver shoot over to far right and Really sped up. He said too bad I got you and you don’t have to worry any longer about the other bad driver. He wrote ticket for 5 over but it was still $100.00. I should have gone to court but didn’t want to miss work. I have seen other Police in that area so Beware.
