I try to stay out outside 285 unless I can't avoid it (taking wife to Dr. for example). We have PeachPass on our vehicles and that helps a lot but even then I tend to take surface streets. We live in the NE suburbs well outside 285 (985 & 85 area). If we are headed south to Florida, I always leave around 2 a.m. but even then it's hit or miss going through Atlanta.
Born & raised in and around Atlanta, I can well remember when the interstates were 2 lanes and traffic was practically non-existent. About the only time you would get jammed up was in the event of a wreck.
