Driven in lots of places with bad traffic. I agree, Atlanta is “unique” with regards to speed, though.
Charlotte traffic is bad, but it moves. Most of the time.
Greensboro is as bad as Charlotte but there tend to be more idiots per capita who failed their driving test who suddenly decided that was OK. Worst is my morning commute. I run into the slow drivers in both lanes who pull that “speed up”’crap when you try to go around them. Ones I hate more than that are the ones who drive slow BESIDE another slow driver in the next lane so no one can get around. Since the highway I go to work on only has 2 lanes per side, that means no one can get past them for miles. Usually the moron in the passing lane speeds up and whips it around the other car about 20 feet before they have to exit. Then they look at you like YOU are the problem when you lay on the horn or give them the “look”.
Yesterday was a first for me though. On my way to work when a young dude in a POS Toyota decided to pass everyone on the exit lane on the right, then try to cut to the passing lane. He slammed on brakes, spun around, hit the concrete barrier and spun 2 more full times. Brought traffic to a stop. Homeboy spins it back around, takes off and exits before hauling arse through some side streets. Left part of his rear bumper in the road. Thankfully he didn’t hit anyone else, so I guess he figured all was good!
