Atlanta is a piece of cake to drive thru. As long as you know where you're going it's not a problem. The traffic on 285 and going thru downtown on 75/85 just flies most of the time. I drove in from MS last weekend and came into Alt on 20, took 285 south to 75 and did this on a Monday at 6:30 pm. Not the first problem or slow down. Drive fast to flow with traffic and know where you're going. Easy!!! I've driven thru and around Atl many times over the years and never worry about traffic there.
