I'm driving to work this morning and merge from 400S to 285E. As I'm physically merging onto 285 I look behind me as usual and see a black car 300+\-ft back w/ a big red sticker on the front window. I think nothing of it and continue to drive normally redlining 3rd and as few times just to enjoy my normal drive to work each morning.
I pass Peachtree Industrial and I'm in the 2nd to left lane. I look behind me and there's an SUV in the left lane and then the same black car behind the SUV. I thought it was a Focus or something so I'm like whatever. What got my attention was that the black car was accelerating and braking very obviously behind the SUV. I'm doing 70mph and I just watch the show. Then the black switches to my lane and comes right up to me. He sits there for a few seconds and then jerks his car to the left and comes passing me. However instead of really passing me he downshifts as he passes me and sit 1 car ahead of me. So to follow the invite I downshifted into 3rd at 70mph and I give him the early warning to be fair. I hit the gas and pass him ... he's trying to move but his car isn't going anywhere. I slow back down to 70mph and the car comes right next to me and just sits there again. I look over and see his fancy gauges, exhuast, stickers, etc. I shift back down to 3rd and wait for his action. He tries to go yet again and I redline 3rd and go into 4th. I pass easily but missed my exit to 85 so I just keep on driving. I took the scenic route to work this morning but it was fun to just drive. It turned out to be a new Civic SI w/ mods ... I have no idea what he was thinking? He had all this bling bling things but nothing which actually helped him. I just don't get some people.
