I was on 85 n yesterday around 7:15 pm. Doing about 70 around hwy 316. I went to go in front of the car in the left lane, floored it whiped in front of him to get out from behind the guy in front of me. Out of the left lane i see a CV with the basher bar come flying around the car behind me then gets behind me and runs right up my ass tailgateing me. Not even sure if it was a cop yet i'm looking in the rear view trying to see and just waiting for the lights. Windows where blacked out all i could see was a hand on top of the steering wheel. Then i see him wave at me in the rear view, goes around and passes me on the right. Dekalb PD on the side. Then i watch him stich threw traffic had to be doing 100+ no lights and that was that. Maybe he wanted to race the WRX or was just scareing me to slow down.
